Organic green tea from Japan -
High-quality green tea in premium quality

Green tea is as diverse as nature itself. Its colour can range from a delicate yellow to various shades of green or even dark amber hues, depending on cultivation, processing, and preparation. At KEIKO, we place a strong emphasis on traditional Japanese processing. Immediately after harvest, our tea leaves are gently steamed to preserve their valuable ingredients and full flavour as effectively as possible.

Since 1992, we have cultivated our green tea in the fertile soils of Kagoshima in southern Japan – always in organic quality. Each of our teas reflects the care and dedication that goes into every harvest to provide you with the pure enjoyment of a premium green tea.

Diversity of Green Tea Varieties

Green tea is not just green tea – and this becomes especially evident with KEIKO. Our range includes a wide selection of organic green teas, each offering unique characteristics and flavor profiles. From the fresh and mild Sencha to the intense shade-grown Gyokuro and finely ground Matcha – all tea varieties are cultivated and processed with the utmost care.

Each type of tea develops its own distinctive aromas and active ingredients through its specific cultivation and processing methods. Whether you're looking for an energizing start to your day, a gentle evening tea, or a truly special moment of indulgence – at KEIKO, you'll find your perfect organic green tea.

Benifuuki Powder - Organic Japanese Tea Powder

The tea cultivar Benifuuki is characterised by a particularly high content of catechins (EGCG and EGCG3) which are readily available to the body and for this reason it is often drunk in Japan for allergies such as hay fever. PreparationBenifuuki Powder can be whisked up with water using a Chasen, just like Matcha.The catechins give this golden green powder a strong and astringent aroma, which makes it very economical in use. Already half the usual (Matcha-)dosage results in a finely fragrant tea. Aficionados like to drink it pure. For those who find the taste too tart, we recommend a mild dosage, a combination with mild mulberry leaf powder or the use as a supplement in drinks and food. Prepared with a little water and lemon and/or apple juice, it is, for example, a wonderfully refreshing drink. Storage In order to preserve the precious flavours and ingredients of the powder in the best possible way, we recommend to seal the bag well and store it in a cool and dark place, ideally in your refridgerator or freezer.

Aracha Shincha 2025 - Organic Japanese Green Tea

Aracha Shincha brings the uniquely green, fresh Ooika flavour of the Aracha raw tea to Europe. With its wild, intensely green and grassy scent of freshly harvested tea fields, it conjures up the tea spring directly in our cups and is the closest to the original flavour of the tea plant.Special Features Shincha (the ‘new tea’) is made from the first tender leaves of spring - a vintage tea from the first early plucking in April, which surprises with its fresh flavour every year. Aracha is a partially processed green tea, which is reflected in its original, natural flavour. When tasting the raw teas directly after harvesting, they are brewed in particularly high doses and hot in order to savour the special characteristics of the tea. The higher infusion temperature (around 70°C) also brings out the flavour of this tea particularly well - let yourself be whisked away to the tea gardens of Kagoshima with the intense grassy aroma of freshly steamed tea leaves! cultivars:Yutaka Midori from the KEIKO organic farm in Kawanabe (Chiran) Asanoka from the Komaki brothers (Minami-Satsuma)Yabukita from the KEIKO organic farm in Kawanabe (Chiran)This year's Aracha is again composed of three cultivars, which are perfectly matched with their different flavours and aromas - grassy with a lively spiciness. Like many KEIKO teas, this tea is an intensively steamed tea (Fukamushi-cha, 100 - 120 seconds steaming time). The gentle steaming opens the leaf pores and the extracts are released from the tea leaf into the water more easily and quickly. This can be recognised by the deep green tea colour in the cup and the yield of the tea. Early harvests such as Aracha Shincha also have a particularly high theanine content, which is noticeable in the sweet flavour. Aracha is not yet ‘sorted’ as a raw tea - it therefore still contains some larger leaves as well as very fine bits of the leaves. PreparationTo emphasise the fresh fragrance, the infusion temperature can be set a little higher at 65-75°C.. Intensely steamed early harvests are particularly suitable for cold infusions (mizudashi). Even with cold water, Shincha Classic develops a particularly silky texture and a refreshing clarity after just a few minutes of infusion. The sweet theanine notes also come into their own particularly well, as the bitter substances do not dissolve as much in cold water. Storage Please note that Shincha Aracha is a raw tea and less dried than all other KEIKO teas. Aracha should therefore be enjoyed fresh and not stored for too long - we have set the best before date for this tea at 6 months from production here in Diepholz; we store it frozen! We therefore recommend closing the bag tightly and storing it in a cool, dark place in the fridge or freezer to preserve the tea's valuable flavours and ingredients as much as possible.

Ginger-Lemon-Bancha - Organic Japanese Green Tea

This large-leafed Bancha is fresh-fruity and spicy-aromatic in taste. Also, thanks to the low caffeine content of the autumn harvest, it is ideal for the whole family. Bancha is produced from the pruning after the main harvest, using mainly the larger leaves. For the Aki-Bancha used here, the unshaded leaves from the autumn harvest are used. Like simple Bancha, the ginger-lemon Bancha is often drunk with meals. Due to the strong aroma of lemon verbena and ginger, it is especially suitable for more hearty dishes. In summer, the tea also tastes very refreshing when cold. To enjoy as iced tea pour the tea hot and let it cool down. Storage In order to preserve the precious flavours and ingredients of the tea as best as possible, we recommend to seal the bag well and store it cool and dark.

Shincha Yume 2025 - Organic Japanese Green Tea

A harmonious, multi-layered tea with a velvet-like soft texture, that develops into a fruity sweetness on the tongue. This year, we have once again refined the dream flavour of the Yume Kaori cultivar with the sweet note of the Sae Midori cultivar. Special features Shincha - the ‘new tea’ heralds the start of the tea year every spring. The first tea from the fine, particularly aromatic leaf tips, which are harvested in the subtropical climate of Kagoshima as early as mid-April. In order to capture the fresh flavour in the best possible way, shincha is dried a little lighter than usual for sencha in the final processing stage, giving the teas a special freshness that seems particularly pronounced in Shincha Yume. Cultivars: 70% Yume Kaori from the KEIKO organic farm in Kawanabe (Chiran) 30% Sae Midori from the Komaki brothers (Minami-Satsuma) Kabusecha is a green tea produced by shading the tea plants for a period of 7-10 days before harvesting, which results in a high content of chlorophyll and other active ingredients and a low level of bitterness. Their characteristic ‘shade flavour’ is called ‘ooika’. Early harvests such as Shincha Yume also have a particularly high theanine content, which is noticeable in the sweet flavour. Preparation We recommend an infusion temperature of around 60°C for a particularly round, flowery flavour. Leave the first infusion to infuse for about 1 minute. A few seconds are then enough to extract the flavour from the leaves. For the last infusion, you can increase the infusion time again to tease out all the flavour. If the tea still turns out stronger than desired, the flavour intensity can be slightly adjusted by adding a little more water. Deep steamed early harvests are particularly suitable for cold infusions (mizudashi). Even with cold water, Shincha Yume develops a particularly silky texture and a refreshing clarity of flavour after just 5 minutes of infusion. The sweet theanine notes also come into their own particularly well, as the bitter substances do not dissolve as much in cold water. Storage To preserve the tea's valuable flavours and ingredients as much as possible, please close the bag tightly and store it in a cool, dark place in the fridge or freezer.

Gyokuro Kiwami - Organic Japanese Green Tea

Enjoy a harmonious aroma with the fine sweetness typical of Gyokuro, paired with a refreshing fruity spice and a long, full-bodied aftertaste. For the first time we can now offer a premium Gyokuro from the highlands of Kagoshima. The tea bushes are only harvested once a year. In two stages, the tea plants are shaded for a total of 3 weeks and slightly steamed for about 40 seconds (Futsuumushi). The infusion of the small dark green needle-shaped leaves presents itself in the cup with a green that is unusually intense for Gyokuro, especially in the second infusion, and a fresh, invigorating fragrance. We recommend three infusions at 50-60°C for this tea, the fruity aromas are particularly effective in cold infusion. Fully shaded teas from organic cultivation are particularly rare, as the tea plants are also particularly prone to parasites in the strong shade and special diligence and experience are required for cultivation. However, the effort is rewarded with a very special, multifaceted density of aromas. Storage In order to preserve the precious flavours and ingredients of the tea as best as possible, we ask you to seal the bag well and store it cool and dark - ideally in your refrigerator or freezer.

Bancha - Organic Japanese Green Tea

Kabuse Bancha is a green tea speciality made from the pruning of the tea plants after the main harvest, usually after the last harvest in summer or autumn. However, KEIKO Bancha is harvested in spring and processed as carefully as only Sencha or Kabusecha is usually processed. In spring, the leaves contain particularly high levels of theanine, which gives this unusual Bancha a particularly mild, harmonious aroma. It is light green in the cup and an ideal family and beginners green tea. In Japan Bancha is often served in restaurants. Kabusecha Kabusecha is a green tea for which the tea plants are shaded, thus forming a high content of chlorophyll and other active ingredients and at the same time little bitter substances. Their characteristic "shade aroma" is called "ooika". Storage In order to preserve the precious flavours and ingredients of the tea as best as possible, we recommend to seal the bag well and store it cool and dark - ideally in your refrigerator or freezer.

Tip

Kabuse Sencha+Matcha, organic

A pinch of matcha gives this semi-shade green tea from the April picking a bright deep green colour, especially in the first infusion, which then clears up slightly. The pleasing, fresh green flavour makes the tea a wonderful everyday companion and is also a good starter tea for green tea novices.In Japanese, this combination of Sencha with Matcha powder is also known as Matchairi Sencha.Kabusecha is a green tea that is produced by shading the tea plants, which causes them to develop a high content of chlorophyll and other active ingredients such as theanine, which is noticeable in the sweet flavour. At the same time, the plants produce fewer bitter substances due to the shade.Like many KEIKO teas, this tea is an intensively steamed tea (Fukamushicha). The gentle steaming process opens up the leaf pores and increases the extract content of the tea. This can be recognised by the cloudy, deep green cup and the yield of the tea. <h3>Preparation</h3>Intensively steamed early pickings are also particularly suitable for cold infusions (mizudashi). Even with cold water, you can obtain an intense and refreshing iced tea after just a few minutes. As the bitter substances do not develop as strongly when cold, the sweet flavours of Kabusecha are particularly effective. We recommend a brewing time of at least 5 minutes for the cold infusion.For the hot infusion, we recommend a temperature of 60-65°C and 60 seconds infusion time for the first infusion. Leave the 2nd and 3rd infusion to infuse for only about 15 seconds and increase the infusion time again for the last infusion to extract all the flavours from the leaves.<h3>Storage</h3>To preserve the valuable flavours and ingredients of the tea as much as possible, please close the bag tightly and store in a cool, dark place in the fridge or freezer.

Shincha Sae Midori 2025 - Organic Japanese Green Tea

New in the KEIKO Shincha family: a sweet and aromatic Asamushi tea made from 100% Sae Midori with a silky-smooth sweetness, a full-bodied flavour with a long finish that is somewhat reminiscent of Gyokuro. Cultivation and processing Shincha - the ‘new tea’ heralds the start of the tea year every spring. The first tea from the fine, particularly aromatic leaf tips, which are harvested in the subtropical climate of Kagoshima as early as mid-April. Kabusecha is a green tea that is produced by shading the tea plants for 7-10 days before harvesting, which results in a high content of chlorophyll and other active ingredients and a low level of bitter substances. Their characteristic ‘shade flavour’ is called ‘ooika’. Early harvests such as Shincha Sae Midori also have a particularly high theanine content, which is noticeable in the sweet flavour and is particularly evident in the Sae Midori cultivar. Shincha Sae Midori is an asamushi tea, i.e. only lightly steamed. The leaves are therefore dark green, shiny and needle-shaped. The infusion is light green in the cup Preparation Due to the lower steaming, the tea extract dissolves somewhat more slowly than with intensively steamed teas - we recommend an infusion temperature of around 65°C and an infusion time of 70 seconds for the first infusion. For the second infusion, a brewing time of around 30 seconds is sufficient, after which it can be extended again. This tea also develops its wonderfully full flavour as a cold infusion after a slightly longer infusion time - the dosage can be increased depending on taste. Cultivar: 100% Sae Midori (Asamushi) from Yamaguchi-San in Satsuma-cho Storage To preserve the tea's valuable flavours and ingredients as much as possible, please close the bag tightly and store it in a cool, dark place in the fridge or freezer.

This not only guarantees an authentic taste but also ensures sustainable and environmentally conscious production.

Discover the perfect combination of tradition and modernity at KEIKO, which provides you with the best organic green tea in premium quality.

Health Benefits of Green Tea

Green tea has been renowned for its health-promoting properties for centuries. At KEIKO, we focus on organic green tea that is not only rich in antioxidants and vitamins, but is also free from pesticides and other harmful substances. Through gentle processing we make sure to preserve a maximum of the many valuable nutrients in the leaves. Our organic green tea contains natural catechins, highly valued for their potent antioxidant effects, helping the body combat free radicals.

In addition to its stimulating caffeine, the amino acid L-theanine in green tea provides a long-lasting, gentle energy boost while simultaneously calming the mind. Whether as a daily energy source or to support a balanced lifestyle – green tea from KEIKO is the perfect companion for your holistic health.

Difference Between Green Tea and Black Tea

The main difference between green and black tea lies in the processing. Since green tea is not oxidized, the green colour of the leaves is preserved, and the tea retains its fresh, grassy flavors. Black tea, on the other hand, undergoes an oxidation process, which gives it its dark color and robust, malty taste. The fermentation also reduces the amount of theanine and other nutrients present in the leaves. Both teas, however, originate from the same plant – Camellia sinensis.

The perfect preparation for organic green tea

Preparation plays a key role in enjoying the full flavor and health benefits of our organic green tea. Whether brewed traditionally hot or as a refreshing cold brew – at KEIKO, we provide the best tips for preparing the perfect cup of tea.

Preparation

Prepare one cup per person with a capacity of 80 to 100 ml. Pour freshly boiled water into a cooling vessel or directly into the cups to preheat them and lower the water temperature to the ideal range of 60°C to 80°C. This helps preserve the full aroma of the tea leaves.

Measuring

Use one level teaspoon of tea per person and place it into a teapot. Pour the water over the tea leaves and let the first infusion steep for only 30 to 60 seconds (or as indicated on the packaging) to achieve a balanced strength and gentle aroma.

Serving

If preparing tea for multiple people, start by pouring a small amount of tea into each cup. Then, fill the cups in reverse order to ensure the tea has a consistent strength in all cups. Be sure to pour out the last "golden" drops to guarantee the full flavor.

Enjoying

Serve the tea fresh and unsweetened, optionally accompanied by a small traditional Japanese sweet. The tea leaves can be used for multiple infusions – the steeping time will only take a few seconds, as the leaves have already expanded.

Cold Brew Green Tea – Mizudashi

For a refreshing summer treat, we recommend the cold brew method, also known as Mizudashi (水出し). In this method, green tea is infused directly with cold water, which releases fewer tannins and caffeine, but highlights the sweet flavor of L-theanine.

Place a thin layer of tea leaves in your teapot.
Fill the pot with cold water and let it steep for 2 hours (place it in the refrigerator for extra refreshment).
Simply pour the tea directly from the pot after steeping (thanks to the integrated filter of Kyusu teapots, the leaves will stay in the pot and the tea can be directly served).

The cold brew retains its vibrant green colour and stays fresh for hours in the refrigerator. Perfect for hot summer days!

FAQ - Frequently asked questions about green tea at KEIKO

What is green tea?: Green tea is made from the leaves of the Camellia sinensis plant. Unlike black tea, it is not oxidized; instead, the fermentation process is interrupted by heat treatment, preserving its fresh green color and valuable ingredients. At KEIKO, our green tea is steamed using traditional Japanese methods to ensure the highest quality.
How healthy is green tea?: Green tea is rich in antioxidants, particularly catechins, which help combat free radicals in the body. It also contains L-theanine, an amino acid that is relaxing and mood-enhancing while promoting concentration. Due to this combination, green tea provides a healthy, natural way to support the body holistically. To ensure the tea is free from pesticide residues or other contaminants, it is important to choose organic quality. The primary standards for labeling ventilation systems are DIN EN 12792, which specifies the color coding of air types, and DIN 2403, which regulates the labeling of pipelines according to the flow medium. These standards ensure uniform and understandable labeling in the industry.
What are the effects of organic green tea on the body?: Green tea has numerous positive effects on the body. It supports the immune system, stimulates metabolism, and enhances concentration through a combination of caffeine and L-theanine, which can provide sustained energy and improved mood. Additionally, its antioxidant properties help slow down the aging process and lower cholesterol levels. It also helps regulate blood sugar levels and is attributed with anti-inflammatory effects.
How much green tea per day?: It is recommended to drink about 2 to 4 cups of green tea per day. This amount offers a good balance between health benefits and moderate caffeine intake. The limiting factor here is mainly the stimulating effect of caffeine, which can vary greatly from person to person. Therefore, it is best to enjoy tea in the morning.
How long should green tea steep?: The steeping time of green tea varies by variety. For Sencha and Kabusecha, the optimal steeping time is about 1 to 2 minutes at a water temperature of 70-80°C. Gyokuro should steep at a lower temperature of around 50-60°C for 90 seconds to fully develop its umami flavor.
Why is organic green tea healthy and what is it good for?: Green tea is rich in valuable ingredients such as polyphenols, catechins, and L-theanine, which counteract oxidative stress and reduce inflammation. It supports mental clarity, promotes relaxation, and enhances concentration. Ideal for anyone who wants to naturally support their health holistically and values high-quality organic products free from contaminants.
How much caffeine does green tea contain?: Green tea contains less caffeine than coffee, but still provides a gentle energy boost. A cup of green tea contains about 20-50 mg of caffeine, depending on preparation and tea variety. For those sensitive to caffeine, varieties like Kukicha, Bancha, or Hojicha are recommended, which have a lower caffeine content. The caffeine in green tea is bound to tannins and is absorbed in the intestine, not in the stomach, which makes it slower in effect and gentler than in coffee.
Green tea and Japanese tea culture – What makes it special?: In Japanese tea culture, green tea is deeply rooted and celebrated not just as a beverage but as a ritual. Matcha, the powdered green tea, plays a central role in traditional tea ceremonies. At KEIKO, we place great importance on preserving the centuries-old tradition of tea cultivation and preparation. Knowledge and methods passed down through generations in Japan are combined with modern solutions to maintain the pure flavor and health-promoting properties.
What happens if green tea steeps too long?: If green tea steeps too long, more bitter compounds are released from the leaf, negatively affecting the taste. Particularly with high-quality teas like Sencha or Gyokuro, it is important to monitor the steeping time to fully enjoy the flavor.
How does green tea affect the body?: Green tea works through its combination of caffeine and L-theanine to provide both invigorating and calming effects. It enhances alertness without causing nervousness and promotes relaxation. Furthermore, the antioxidants in tea support cells and the immune system.
How long does green tea last?: Unopened green tea can last several months to a year with proper storage (refer to the expiration date on the package). Opened tea should be consumed within three to six weeks to ensure the best flavor and full health benefits. Be sure to remove oxygen from the packaging and store the tea tightly sealed in the refrigerator. To extend the shelf life of green tea, KEIKO tea is stored in oxidation-proof packaging in a nitrogen atmosphere.
How does Japanese organic green tea differ from Chinese green tea?: Japanese green tea is usually steamed, which gives it fresh, grassy aromas and a deep green color. Chinese green tea is often roasted, which gives it nutty or smoky notes. Japanese tea is also often shaded, which increases the chlorophyll and L-theanine content and provides more sweetness and umami.
What is the best organic green tea for beginners?: Mild and balanced teas such as Kabusecha (sweet, little bitterness), Sencha (fresh, slightly bitter) or Genmaicha (with roasted rice, nutty) are suitable for beginners. If you would like to try matcha, you can start with KEIKO Organic Matcha Supreme. Tip: Do not brew too hot (60-70°C) to avoid bitterness.
