Whipped cream toppings, cold foam, espuma and infused syrups are everywhere on café and bubble tea menus — and behind almost all of them is a simple tool: the 8g N2O cream charger. This guide covers what cream chargers are, whether they’re legal in the UK in 2026, how much whipped cream you get per charger, and how to buy them wholesale for your café or bubble tea shop.
What is a cream charger?
A cream charger is a small steel cylinder filled with 8g of food-grade nitrous oxide (N2O). Fitted into a cream whipper, the gas dissolves into liquid cream under pressure; when dispensed, it expands into light, stable whipped cream. One 8g charger whips roughly 0.5L of cream into up to 1.5L of whipped cream. The same technique creates savoury foams, fruit espumas and rapid infusions.
Are cream chargers legal in the UK in 2026?
Yes — for culinary use. Although nitrous oxide was added as a controlled substance in 2023 to tackle recreational misuse, the law explicitly exempts food-grade N2O used for catering and food preparation. Cafés, bubble tea shops, restaurants and caterers can buy cream chargers — including in bulk — entirely legally. Purchasers must be 18 or over, and products are sold strictly for food and beverage preparation.
How many cream chargers does a café need?
It depends on volume, but a useful rule of thumb: one 8g charger tops roughly 10–15 drinks with whipped cream, or fewer if you’re building thick cold-foam caps. A busy bubble tea shop serving cream-topped or cheese-foam drinks can easily go through a 24-pack in a day or two, which is why most operators buy by the case. Buying wholesale keeps your cost per drink down.
Choosing chargers and a whipper
- Chargers: Standard 8g N2O chargers fit all standard whippers. Look for 100% recyclable steel and pure food-grade gas for clean flavour. Our 24-pack Unite 8g cream chargers are a reliable everyday choice.
- Whipper: A 0.5L cream whipper suits most café counters; a 0.5L charge makes up to 1.5L of cream. See our 0.5L cream whipper.
- Storage: Keep chargers cool and dry; dispose of empties with steel recycling.
Uses in cafés and bubble tea shops
Beyond classic whipped cream, chargers power cheese cold foam and salted-cream caps for milk teas, light fruit espumas for fruit teas, and fast syrup or tea infusions. They’re a low-cost way to add a premium, photogenic finish that lifts perceived value and average order size.
