PrimeWhip Food-Grade Cream Charger 320G Watermelon

Bar teams tend to reach for the 320g when the back bar is tight on space. This one carries a watermelon note through the gas, which suits summer sours, melon foams and light dessert toppings. Purity is stated at 99.95%, with no oily carry-over to sit on top of a drink. Because one cylinder replaces upwards of 45 single-use 8g chargers, the bin behind the bar fills with packaging far more slowly. Fit a pressure regulator between cylinder and siphon.

Fitting the 320g into a busy bar

Back-bar space is usually the reason a site picks the 320g over PrimeWhip's larger cylinders. It holds roughly half the fill of the 640g and only a small fraction of the two largest bodies, so it sits in a service well or under-counter fridge alongside spirits and mixers rather than needing a shelf of its own.

That footprint matters more on a watermelon-driven summer list, where the cylinder is competing for the same limited space as ice wells, garnish trays and bottles brought out specifically for the season.

A quiet single-site bar is also less likely to need the 640g body at all, since the smaller cylinder alone can cover a modest weekly cocktail run without ever being swapped mid-shift.

Fitment and compatibility

It is a sealed cylinder, not a threaded 8g cartridge, so it needs a pressure regulator on its neck to feed a standard whipping siphon rather than clipping straight into a charger holder. The regulator, once bought, is reusable across any PrimeWhip cylinder size the bar moves to later.

When to move up to 640g

If a watermelon promotion is running for a full season rather than a single weekend, the 640g cylinder double the fill of this one usually means fewer cylinder changes across the same run of service, at the cost of a bit more storage space behind the bar.
