Review: Simple unsweetened green tea - I usually keep a few bottles of unsweetened tea in the fridge, and this one has the simple green tea taste I was looking for. There is a mild bitterness at first, but the finish is clean and not too strong. It tastes best cold, especially with sushi, fried rice, or a heavier lunch. The 16.9 ounce bottle is a good size for one meal, and the cap closes securely if I do not finish it. It reminds me of the bottled green tea served at Japanese restaurants and is easy to drink with food. Review: The gold standard for real, sugar-free green tea. - Pros: Authentic Japanese Flavor: If you are tired of American-style "green teas" that are loaded with sugar, honey, or artificial fruit flavors, this is exactly what you are looking for. It tastes precisely like a fresh pot of brewed Japanese sencha—earthy, crisp, clean, and slightly grassy. Zero Sugar or Sweeteners: It has zero calories, zero sugar, and absolutely no artificial sweeteners (no stevia or erythritol to leave a weird aftertaste). It is pure, guilt-free hydration. Great Visual / Pop Culture Nod: If you watch anime or have traveled to Japan, you’ll immediately recognize the iconic green bottle. It's great to toss into a gym bag or leave on an office desk. Nice Refreshing Pick-Me-Up: It features a medium caffeine boost that gives you a gentle wave of focus and mental clarity without the intense jitters or crash of an energy drink or strong coffee. Cons: An Acquired Taste for Some: Because it is completely unsweetened, it does have a natural, subtle touch of bitterness and a deeply earthy profile. If you are used to sweet iced teas, it might take a few bottles to adjust to the flavor profile. Price Fluctuations: Buying it in bulk online can sometimes be subject to price shifts depending on stock levels, though it usually still beats buying individual bottles at a specialty market. Final Verdict: This is hands-down the best ready-to-drink bottled green tea on the market. It is crisp, refreshing, and holds true to traditional tea culture. If you love pure tea or want a healthy, crisp alternative to water and sugary sodas, a 12-pack of this is an absolute must-have. ## Features - WHOLE LEAF TEA: Oi Ocha Green Tea is brewed from first flush whole green tea leaves grown in Japan not from tea powder or concentrate; using the whole leaf means our teas don’t lose any of the health benefits that are naturally present in green tea leaves - CLEAN AND REFRESHING: Oi Ocha Unsweetened Green Tea has is natural clean tasting and refreshing; putting our iced green tea in a convenient ready to drink bottle means you can have your hydration on the go; it makes a great alternative to traditional sodas - LOW CALORIE: ITO EN's Oi Ocha Green Tea has no sugars or artificial sweeteners, making it a delicious, substitute for your usual sugary soda or flavored coffee at only 5 calories; try our naturally vitamin and antioxidant rich tea, and you may never look back - ANTIOXIDANT RICH: brewed from premium Japanese loose tea leaves, Oi Ocha provides natural catechin tea antioxidants and other healthy goodies; a key to good health, happiness, and wisdom, green tea is the perfect refreshment for your health and well-being - NO ADDITIVES: ITO EN teas are brewed with no artificial colors or flavors so you can be confident that the only things in our bottles are delicious, healthy green tea and natural flavors; it's a refreshing beverage you can always feel good about drinking ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0017T2MWW | | Allergen Information | Dairy Free, Gluten Free | | Best Sellers Rank | #376 in Grocery & Gourmet Food ( See Top 100 in Grocery & Gourmet Food ) #2 in Green Tea | | Brand | ITO EN | | Brand Name | ITO EN | | Caffeine Content Description | Medium Caffeine | | Container Type | Bottle | | Customer Reviews | 4.5 out of 5 stars 8,603 Reviews | | Each Unit Count | 16.9 | | Flavor | Green Tea | | Global Trade Identification Number | 20835143001058 | | Item Dimensions | 2.6 x 2.6 x 8.11 inches | | Item Form | Liquid | | Item Type Name | Green Tea | | Item Volume | 202.8 fluid ounces | | Item Weight | 12.7 pounds | | Liquid Contents Description | Coffee & Tea Drinks | | Manufacturer | Ito En | | Model Number | 835143001047 | | Number of Items | 12 | | Package Size Name | Pack of 12 | | Part Number | 835143001399 | | Product Benefits | Low Calorie, Antioxidant Rich, Healthy Refreshment | | Region of Origin | Asia | | Special Ingredients | Green Tea | | Specialty | Antioxidant, Low Calorie, Natural, Organic, Unsweetened | | Sweetness Description | Unsweetened | | Tea Variety | Green | | Unit Count | 202.8 Fluid Ounces | ## Product Details - **Brand:** ITO EN - **Flavor:** Green Tea - **Item Form:** Liquid - **Tea Variety:** Green - **Unit Count:** 202.8 Fluid Ounces ## Images ![Tea Oi Ocha Green Tea, Unsweetened, 16.9 Ounce (Pack of 12) - Image 1](https://m.media-amazon.com/images/I/81EblbQVAPL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: is there caffeine in this?** A: Please see http://www.itoen.com/ready-to-drink/oi-ocha/oi-ocha-dark-16-9-fl-oz-12-bottles-case, which is worded confusingly, saying that it has 50 mg per 8 oz even though each bottle is 16.9 oz, so it's actually a bit north of 100 mg. If you want less caffeine, the non-bold version only has 60 mg per bottle. **Q: Does the cold green tea have the same health benefits as hot green tea?** A: I think what you want to ask is: does bottled tea have the same health benefits as freshly brewed tea? I heard that it doesn't. I think you lose some healthy components like within an hour after it is brewed. I don't think Bottling preserves everything good in fresh tea. I bet this has been researched. Wonder what good things are left in bottled teas, and if there's any Bad components created. Pretty sure plastic bottles will add some bad components. **Q: Is this product made in Japan or China? I've seen product listing that state one or the other ... Thank you!** A: This clearly states on the box they come in and the bottles that it's a product of Taiwan. It is misleading because their Amazon account says made in Japan etc... The leaves might be from Japan but it's not a product of Japan. I was dissapointed when I saw this but I still like the tea. **Q: Do you have glass or metal bottles as an option?** A: No just plastic bottles ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple unsweetened green tea *by G***E on July 26, 2026* I usually keep a few bottles of unsweetened tea in the fridge, and this one has the simple green tea taste I was looking for.
