There are more than 20 flavors of GT's Kombucha, all vegan, gluten-free and non-GMO.

Time and time again we can't help but reach for Synergy Trilogy, a slightly acidic and fruity sparkling elixir that will definitely give you a little buzz — the perfect pick-me-up for that afternoon slump. GT is also impressively low-glycemic with just three to four grams of sugar per serving. For a real boozy sensation, try the brand's "Classic" line that was first introduced in 1995 and features bottles with more than 0.5% alcohol. In other words, you must be 21 or over to purchase these bad boys.
