Your ultimate guide to the best kombucha

Kombucha: health elixir or hype? We've got the lowdown on the popular drink that has shifted from the health set to the mainstream.

Move over sugary soft drinks and juice there’s a new drink in town. Kombucha, the low sugar, refreshing, effervescent, fermented fruit flavoured alternative is popping up everywhere from cafes to supermarket shelves.

But wait there’s more, many kombucha brewers claim that drinking it is great for your gut and your general well being.

And while kombucha is enjoying a moment in the sun as one of the hottest health trends around, we take a level-headed look at whether this new "superdrink" really is healthy?

What even is kombucha?

Kombucha is made from fermented sweetened black or green tea and fermented with a scoby (symbiotic culture of bacteria and yeast) and should contain probiotic cultures (AKA the little floaty bits). While the colour and taste tends to vary, it is often a cloudy yellow shade and has a sharp sherbet like taste with a slight fizz. It’s also got a small amount of alcohol due to the fermentation process, but not enough to have any noticeable effect.

What in the world is a SCOBY?

If you would like to make your own kombucha you can can buy a SCOBY from health food stores, or even make your own from scratch using sugary tea “activated” by live cultures. You can either buy a prepared culture mix or can even initiate the fermentation process by adding some store-bought kombucha to your tea and waiting for it to ferment and the SCOBY to grow.

Of course, if you’d like all the benefits of kombucha, without the hassle, you can buy bottled kombucha which is increasingly available in shops, supermarkets and service stations. There are no standard requirements for what makes kombucha so the ingredients (and benefits) of store bought kombucha are likely to vary.

As a general rule you can expect to find these ingredients in your kombucha:

• Probiotics. This is the biggest draw card, as each cup of kombucha can have billions of good bacterias such as Lactobacillus, Acetobacter and S. Boulardii.
• Caffeine. Most kombucha will have a small amount of caffeine, thanks to the tea.
• Sugar. Kombucha will also have some sugar content, although actual amounts will vary from brand to brand as the fermentation process eats up the majority of the sugar.
• B vitamins. Most kombucha is also rich in B-complex vitamins.

What are the benefits of drinking kombucha?

Some of the claims about kombucha are totally over the top “an immortal health elixir!,” “supports the immune system!” and even “prevents cancer!” - however there are some genuine benefits.

One of the main selling points of kombucha is that it’s rich in probiotics, which can help balance your gut flora and encourage digestion. Unbalanced gut flora is blamed for a range of ailments including IBS and low energy..

The broad B vitamin spectrum may also be helpful for vegans and vegetarians who might not be able to get enough B vitamins from their regular diet.

What is the best kombucha flavour?

These days, store-bought kombucha comes in a range of flavours. For a healthier option, we suggest buying kombucha flavoured with fruits or herbs after the fermentation process. There is also a wide selection of infused kombucha flavours.

However, if you have more of a sweet tooth, or if you’re not a huge fan of kombucha’s distinctive flavour there are plenty of products enhanced with sweetened flavourings, just keep an eye on the sugar content.

Our favourites are:

• Ginger
• Lemongrass
• Berry

When is best to drink kombucha?

Drinking kombucha on an empty stomach maximises the health benefits, especially if you’re drinking it to aid digestion.

However, some people might find it a bit strong on an empty stomach and a few people have reported mild nausea after drinking kombucha first thing in the morning but eating a little bit before you drink your kombucha (but not too much) can help.

Does kombucha cure hangovers?

One of the most popular times to drink kombucha is in the morning after a big night out and many people report that Kombucha aids hangover recovery.

Kombucha is lightly caffeinated drink which will definitely help regulate your blood sugar and help you feel more like yourself again when you have been rough on your body the night before. The shot of probiotics will can help you recover, as alcohol contains a lot of unprocessed sugars and too much alcohol consumption without enough water intake will make you feel queasy.

What is the best kombucha to drink?

How to choose the best kombucha

1. Look at the packaging

• Darker is better. Light damages probiotics so the best and most active kombucha will come in dark-coloured glass bottles.
• Go for glass. Glass is by far the best choice for kombucha packaging. Other materials, such as plastics and aluminium, will degrade slowly over time, especially in contact with alcohol, even at small amounts. Glass is far sturdier and will better preserve the kombucha’s potency without interfering with the natural fermentation process.

2. Read the ingredients list

• Natural flavours. We will say it again: flavoured Kombucha is delicious but be sure to know what kind of flavouring is used by the kombucha brand you buy. It is relatively easy to use real fruit and herbs to infuse kombucha with creative flavours, but can be faster and more cost-effective to use powdered fruit flavouring or even sweetened artificial flavoring to get a palatable taste. This really defeats the purpose of drinking a probiotic and will mess with the balance of good bacteria – both in the bottle and in your stomach. Stick to natural infusions to get the best flavour.
• Sugar content. Another shortcut to a kombucha drink that is palatable is to add extra sugar. While the natural fermentation process will “eat” up sugars, there is a limit, so make sure your kombucha doesn't have a heap of added sugar. (A good guide is no more than 2.5grams of sugar per 100mls.)

3. Focus on the fermentation process

• According to kombucha experts, it takes 21 days for the fermentation process to take place and for the drink to become active and healthy to drink. Take a look at the label. Higher-quality kombucha brands will list their process and tell their customers how long the contents have been fermented.

Is there a lot of sugar in kombucha?

Kombucha itself is made with sugar which is essential to any fermentation process. However, during fermentation, the sugar is consumed and converted into bacteria so it is possible to make and buy kombucha with a low sugar content.

The sugar levels that are left post fermentation depend on the brand you buy. The general wisdom is that home-brewed kombucha tends to have a lower sugar content, while many of the commercial brands may add extra sugar, artificial sweeteners or fruit juice to make the drink more appealing. However, there are plenty of brands that offer low-sugar options and it’s simply a case of reading the label.

Is kombucha really good for you?

The jury is out on this one. While a well-made kombucha can be rich in probiotics and can encourage beneficial gut flora, it is certainly no cure all.

But if you like the taste, are looking for a refreshing alternative to sugary soft drinks or even wanting to swap out alcohol for a glass of ‘booch’ - then we say go for it.
