How Much Kombucha Should You Drink a Day? A Craft Brewer's Guide
The short version: For most people, enjoying one to two cans (250ml to 660ml) of kombucha a day is the perfect amount to replace sugary soft drinks or alcohol. If you are new to traditionally fermented drinks, start with half a can (around 150ml) and gradually build up as you get used to the crisp, complex flavour profile.
We get asked this question a lot. Because kombucha has historically been spoken about in hushed, almost clinical tones, people often treat it like a functional medicine or a daily dose of something they have to measure out.
But here is the truth from a craft brewer’s perspective: authentic kombucha is simply a premium, slow-fermented beverage. It is a food, not a medicine. Asking how much you should drink is a lot like asking how many glasses of premium sparkling water or craft soda you should have in a day. It entirely depends on your lifestyle, your sugar goals, and the kind of rituals you want to build into your week.
At Nunc, we brew Jun Kombucha—a rare, incredibly delicate style of fermented tea. While 99% of standard kombuchas are brewed with black tea and heavy white cane sugar, we brew exclusively with organic green teas, select botanicals, and raw local honey. The result is a dry, crisp, and deeply complex drink that feels like an adult reward, making it the ultimate alternative to alcohol for your evening wind-down.
Here is our practical guide on how to integrate this premium drink into your daily routine, how much to pour, and why timing matters for your 6 PM reset.
Recommended Daily Intake at a Glance
To help you understand how craft Jun kombucha fits into your daily routine compared to other options, we have broken down the key differences:
| Beverage Type | Recommended Daily Volume | Taste Profile | Best Occasion |
|---|---|---|---|
| Nunc Jun Kombucha | 1 to 2 cans (330ml – 660ml) | Dry, crisp, delicate, and deeply complex | The 6 PM Reset; a sophisticated alternative to alcohol |
| Standard Kombucha | 1 bottle (approx. 250ml – 330ml) | Vinegary, highly acidic, or artificially sweetened | Daytime refreshment |
| Mass-Market Sodas | As minimal as possible | Extremely sweet, syrupy, and simple | Quick energy/sugar hit |
How to Start (If You are New to Fermented Drinks)
If your palate is more accustomed to heavily sweetened sodas or standard juices, the complex bite of traditionally fermented Jun can be wonderfully surprising. Because it is slow-fermented, it has a sophisticated, adult mouthfeel with a dry finish.
When starting out, we suggest introducing it gradually:
- Days 1 to 3: Pour half a can (about 150ml) into a nice glass over ice. Enjoy it alongside a light meal or right at the end of the day. This lets your palate adapt to the clean, crisp acidity of fermented green tea and raw honey.
- Day 4 onwards: Upgrade to a full 330ml can. This is the perfect single-serving size to replace your usual evening beer, cider, or spirit-and-mixer.
Why We Ferment with Honey Instead of Sugar
The reason Nunc is so easy to drink throughout the day—and why you can comfortably enjoy more than one can—comes down to our fermentation process. Standard kombucha relies on large amounts of white cane sugar, which can leave a heavy, vinegar-like acidity that limits how much you want to drink in one sitting.
We brew Jun Kombucha. Jun is fermented using raw local honey and premium green teas (like organic Darjeeling). The cultures consume almost all of the honey during the fermentation process, leaving behind an incredibly smooth, crisp, and dry drink. Because it lacks that harsh vinegar burn, it is exceptionally refreshing and pleasant to sip at any time of day.
The 6 PM Reset: Finding Your Evening Alternative
For many of us, the most challenging part of cutting back on alcohol isn't the alcohol itself; it is the loss of the ritual. When the laptop lid closes, the emails stop, and the clock strikes 6 PM, your brain craves a physical signal that the workday is officially over.
Pouring a cold can of Nunc into a premium glass gives you that exact transition. Whether you choose the botanical, gin-like complexity of our Juniper & Lime, the citrusy, bitter depth of Hops Monster, or the gentle, warm kick of Mango Buzz (which combines dry mango notes with turmeric and ginger), you get a dry, sophisticated drink that satisfies your craving for a complex beverage, without the alcohol.
Because it is low in sugar and completely free of artificial sweeteners, you can enjoy a couple of cans over an evening without any guilt, sugar crashes, or next-morning fog.
What About Caffeine and Sugar Content?
When planning how much kombucha to drink in a day, two common factors to keep in mind are caffeine and sugar:
1. Trace Caffeine
Because Jun is brewed from organic green tea, it naturally contains trace amounts of caffeine. However, during the fermentation process, much of this is naturally reduced. A standard can of Nunc contains only a tiny fraction of the caffeine found in a single cup of green tea or coffee. Unless you are exceptionally sensitive to caffeine right before bed, enjoying a can during your 6 PM reset will not disrupt your sleep cycle.
2. Lower Sugar, Never Sweet
We are highly opinionated about sweetness. Many commercial soft drinks are packed with sugar to mask their lack of flavour. Even some standard kombuchas add excessive fruit juice or syrups after fermentation, making them cloyingly sweet. Nunc is brewed to be dry. We do not add juices or sweeteners post-fermentation. This means you get a crisp, clean drink that is good for you, respects your palate, and doesn't overload your daily sugar intake.

Frequently Asked Questions
Can I drink kombucha every day?

What is the best time of day to drink kombucha?
The best time to drink kombucha is during your transition moments, particularly the 6 PM reset. Pouring a cold can into a nice glass at the end of the workday provides a dry, sophisticated bite that mimics the ritual of an alcoholic drink without any of the alcohol.
Does kombucha contain caffeine?
Yes, kombucha contains trace amounts of caffeine naturally derived from the green or black tea base. However, the amount is minimal—significantly less than a standard cup of tea or coffee—making it suitable for enjoying during an evening wind-down without impacting your sleep cycle.
Is kombucha high in sugar?
Craft kombucha, especially honey-fermented Jun, is exceptionally low in sugar. While raw honey or sugar is required for fermentation, the cultures consume almost all of it during the process, resulting in a dry, crisp, and refreshing drink that is never sweet.
Can I drink kombucha as an alternative to alcohol?
Yes, craft kombucha is an excellent alternative to alcohol. Its complex fermentation process delivers an adult depth of flavour and a dry, sophisticated bite that satisfies the craving for a complex evening drink, helping you switch off during your 6 PM reset.
Should I drink kombucha on an empty stomach?
You can drink kombucha at any time, whether on an empty stomach or alongside a meal. If you are new to fermented drinks, we suggest starting with a small serving with food to see how your palate enjoys the crisp, dry acidity before moving to everyday consumption.
