[This review was collected as part of a promotion.] Not sure if I received an old bottle or something but this tasted disgusting and I’m actually a big fan or regular green tea and matcha green tea. I don’t know what was up with this one but I personally did not like it. It also has a veryyyy high amount of sodium for a drink stick to water y’all.

[This review was collected as part of a promotion.] This had a lovely smoky flavor. That's my favorite type of green tea. The bitterness balance was just right. I wish it came in a glass bottle instead of plastic and was organic. Overall, it was refreshing and convenient.

[This review was collected as part of a promotion.] I had never heard of this brand before, but was pleasantly surprised! First off, this green tea is high quality! It's made with quality ingredients and you can tell when you take a sip. There aren't a ton of ingredients either which is good, because each ingredient used is something that is good for you! There is just water, green tea and vitamin c. This tea is also unsweetened and has only 5 calories per bottle! There is caffeine because it is tea, and the caffeine content is 60 mgs per bottle, which isn't bad! The flavor isn't bad either! I do highly recommend this tea, especially if you are looking for a tea that tastes good, and is good for you! Give it a try, you will be happy that you did!

[This review was collected as part of a promotion.] Ito En Tea Oi Ocha is the best, refreshing unsweetened green tea one can have. I used to drink this on a regular basis while living in Japan, so it was a delight to learn about its availability in the US. If you're searching for a mild green tea flavor, this is not what you're looking for! Oi Ocha's makes a bold statement with every sip along with a smooth dose of caffeine. Although some people prefer to drink it at room temperature, an ice-cold bottle on a hot day is the perfect way to enjoy this beverage. This will be my go-to drink for ages!

[This review was collected as part of a promotion.] Most of the green tea I can buy never had that true green tea flavor. This one definitely changed that for me and I love it. The true flavor and the energy I get from it is amazing. And it doesn't break my calorie allotment. If I can find more I'll be in for a few more bottles!

[This review was collected as part of a promotion.] It tasted like water and not in the good way . Usually when I drink unsweetened green tea it still has taste, but this barely had any taste at all, like someone drove next to a green tea farm and got a hint of imagination of what green stea might taste like . La Croix has more taste

[This review was collected as part of a promotion.] I am really enjoying this Ito En Oi Ocha unsweetened green tea. I was afraid it would taste bitter as it is unsweetened but it seems perfectly brewed. It has a nice gentle green tea flavor- not overpowering. I like to drink it for a cool burst of energy without feeling overloaded with sugar. I also love that it has tons of vitamin C.

[This review was collected as part of a promotion.] This wasn't my favorite green tea. I love unsweetened tea this just had that too bitter at the end for me. It's good but I can't see myself enjoying it all the time. If I wanted just half the other part would only last 2 days in the fridge after opening. Tea without preserves should still last at least a week in the fridge.

[This review was collected as part of a promotion.] I enjoy cold and hot tea so I decided to try Ito En Oi Ocha green tea. It tastes good, I prefer a bit sweeter so u added Splenda. Also pours it over ice it tasted good like this. I would buy it again.

[This review was collected as part of a promotion.] This is definitely not for me! I tried to make myself like it, but I just couldn’t. Maybe if I would have been one of those kids who liked to eat dirt then maybe it would be for me, but I don’t. It tastes like they dug the tea leaves straight from the ground and made it. Dirt, tastes like dirt.
