From box to first bubble in three minutes — and a refill loop behind it that means you never run out. Here's the whole system, in four moves.
The Starter Kit and Family Pack ship with CO₂ cylinders and BPA-free bottles included — everything you need for the first month of fizz in one box.
Fill the bottle with cold water, twist it in, and press. Four bubble levels — from a gentle pétillant to a sharp, prickly fizz. No electricity, no batteries, no waiting.
One cylinder makes about 60 litres. When it runs low, order a swap — a driver brings a freshly pressure-tested cylinder the same day and takes your empty back to the lab.
Put refills on a schedule and we deliver before you run out, with a subscriber discount applied automatically. Pause, skip, or cancel anytime from your account.
