"Ginger with the volume knob snapped off."

Root Cause is the one for people who think kombucha should actually taste of something. Fermented on a black tea blend with a proper, generous hit of fresh root ginger, not a whisper of it, an actual punch. Small batch, live, unfiltered, and the closest thing in the Gut Feeling range to what I'd reach for myself on a Friday night.

Packs and boxes count as one item towards the box deal, as they're already discounted.

About this kombucha

This isn't ginger as an afterthought. It's the whole point of the bottle.

Why you'll love it

It's what ginger beer wants to be when it grows up. A proper punch of fresh root ginger, a black tea backbone and a tang that slaps you awake in the nicest possible way. The Friday night bottle when you're driving, or when you're just not drinking and can't be bothered explaining why.

What's actually in it

Filtered water, cane sugar, tea mix, kombucha cultures, ginger juice. Fresh root ginger, a black tea base, a live SCOBY doing its thing, and nothing artificial anywhere near it. That's the entire ingredients list, no extract percentages needed here, just real ginger.

500ml, not 330ml, on purpose

Every other kombucha in the shop is 330ml. This range is 500ml because a small glass, about 150ml, is plenty, which makes one bottle last about three days. That's a routine, not a random purchase.

It's also properly good as a stand-in for a bottle of wine. The ginger heat and the tang from the fermentation give it enough backbone to hold its own with dinner, pour it into a wine glass and nobody's going to ask why you're not drinking.

The proper stuff

Unpasteurised kombucha, fermented on a black tea blend with a generous hit of fresh root ginger. Cloudy, live and short dated. The murky bits mean you no harm. Serve ice cold. Live. Unfiltered. Banging.

This is a fermented tea drink, not a medicine. It doesn't diagnose, treat, cure or prevent anything. Enjoy it as part of a normal, varied diet, and drink it because it's genuinely good, not because a label told you to.

Want the science? Here's what the research actually says about fermented drinks, minus the hype.

Raw and alive

Raw means unpasteurised. The bacteria and yeasts from fermentation are still in there, which is why it needs to stay cold.

Like all kombucha, it has a trace of alcohol from fermentation, always under 0.5% ABV, and a little caffeine from the tea it's brewed with.

Storage: keep it cold

Fridge it from the moment it lands to the moment you drink it. Warm raw kombucha gets lively, so open it slowly over the sink if it's been out. Once open, keep it in the fridge and finish it within a few days.
