I was in Denver for an event and while I was in the area I stumbled into a brewery thinking, "They can't only have beer on their menu. They must have a cider!" (Side note: I hate beer). Long story sho...rt the only thing they had on their menu that wasn't beer was Kombucha!

I ordered the Kombucha begrudgingly and boy was I surprised. It was so GOOD! Light and refreshing with a mint and sage undertone. It was the perfect remedy for the early cold symptoms I was suffering and I happily ordered another glass.

I told the bartender how much I loved it and he informed me that the Upstart Kombucha was local in Boulder. To bad I'm not local and my flight left the next day :/ I will return in June and hopefully get a chance to check out their taproom in Boulder! I'll do my best to drink them out of stock as I don't think a Growler will survive the flight home!

I drink kombucha to help balance out thr other things I have consumed that
are not as healthy! This is all-natural, 100% raw, vegan, and gluten free. As I get older I realize how important the health... benefits that vitamins and probiotics in kombucha provides! See More

Can you believe I have never had kombucha before today?!! I had the Chai Spice at Woods Boss Brewing and it is hands down the best thing I have ever had. I want to drink this everyday! I鈥檓 pretty sure... Upstart has ruined all other kombucha companies for me as I don鈥檛 think anyone can top it. Ahhhhh so good! See More

The rosebud is my favorite kombucha hands done. I love being able to support local businesses. A sign in the front of the business show their general attitude which fits the local Boulder vibe so well.... Prices at the taproom are very reasonable and they have some really cool merchandise as well See More

I鈥檝e been a huge fan of Upstart Kombucha ever since I first discovered it many years ago! The rose bud is definitely a favorite of mine. Whenever introducing people to kombucha for the first time, I a...lways have them try rosebud first! Rosebud is pretty mild and not a very acidic kombucha which is great for beginners. The other flavors are also equally great! Wish they鈥檇 come out with more flavors since the ones they currently have are so great! See More

Upstart Kombucha is some of the best Kombucha around! It's mild flavor is perfect for your first taste of Kombucha; Rose Bud is my favorite flavor. Not only does this Kombucha taste amazing, but it ma...kes me feel amazing. It is so refreshing, light, and nourishing for the body. I hope to try new flavors in the near future!! See More

Such a Boulder company. The tap room feels like a hip brewery, but it's better than that because it's kombucha :) My favorite flavors are the Mint Green & the Lemon Ginger

I always thought you had to drink water to stay alive, turns out you can survive on Upstart Kombucha though. Seriously though, I live for this stuff; and nothing beats a jaunt over to the taproom for... a tasting and chat with the wonderful people working there. See More

While I visited Colorado- I found this brand and fell in love with the Rose Bud.
Now I am back in Texas and none of the Kombuchas here satisfy like Upstart did.
If I ever go back to Colorado this is of the first drinks I'll hunt down. See More

I love Upstart! They have such amazing flavors, and aren't overly sweet like a lot of commercialized kombuchas these days. Rose bud always makes me feel better on a tender hearted day!!
