Siphons and Cartridges

Siphons and N2O cartridges are an essential part of modern kitchen equipment — this technique allows chefs and baristas to create airy textures, foams and whipped cream with precise, repeatable results. The use of this equipment has become standard in premium restaurants, patisseries and specialty coffee bars.

Cream siphons and their operation

Pour liquid cream or another liquid into the cream siphon, screw in a N2O cartridge, which dissolves the liquid under pressure. When the handle is pressed, the liquid is released as airy whipped cream — the N2O gas, expanding, creates the characteristic airy structure. The finished whipped cream can be stored in the siphon in the refrigerator for 24–48 hours, making work easier in busy kitchens.

Professional cream siphons are available in 0.5-litre and 1-litre capacities. A larger capacity reduces the need for repeated refilling during busy service. A stainless steel body ensures durability and easy cleaning.

N2O cartridges and their types

Standard N2O cartridges (8 g) are suitable for 0.5-litre siphons and provide one refill cycle. Larger cartridges (16 g) are suitable for 1-litre siphons with a greater volume of whipped cream. Cartridges must meet food-grade standards — food-safe (N2O) is used, not industrial nitrous oxide.

CO2 cartridges are used in soda siphons for preparing sparkling water and carbonated cocktail bases. In bars, soda siphons with CO2 cartridges are a classic cocktail-making technique. Cartridges should be stored in a dry, cool place, protected from direct sunlight.

Modern kitchen texture techniques

Siphons are not only for whipped cream — they can also be used to prepare savoury foams (fish broth foam, truffle oil espuma), fruit foams for desserts and cocktail decorations. In molecular gastronomy techniques, siphons are an essential tool for creating airy textures that are not possible with traditional methods.

Cold smoking guns combined with siphon techniques further expand texture possibilities — the preparation of flavoured foams and smoked whipped cream is a popular addition to premium restaurant menus. See also whisks and Pastry Tools.

HACCP and safe usage requirements

N2O cartridges must be used according to the manufacturer’s instructions — incorrect use of siphons can pose safety risks. Cartridges must not be stored at high temperatures or in direct sunlight. Used cartridges must be disposed of as metal waste in accordance with waste sorting regulations.

Food siphons must be disassembled and washed after each use — internal parts and nozzles must be cleaned of cream residue to prevent bacterial growth. Siphons with cracks or deformed bodies must not be used, as defects in pressure vessels pose a safety risk.

HoReCa usage scenarios

In fine dining restaurants, siphon whipped cream is used for decorating desserts, preparing savoury soup foams and creating cocktail components. In specialty coffee shops, siphons with coffee cream provide a precise liquid coffee cream portion for each cup. In bars, CO2 soda siphons are a classic cocktail-mixing tool.

Frequently asked questions

How many N2O cartridges are needed for one siphon refill? A standard 0.5-litre siphon requires one 8 g N2O cartridge. A 1-litre siphon requires two 8 g cartridges or one 16 g cartridge. The number of cartridges may vary depending on the viscosity of the liquid — a thicker base may require an additional cartridge.

Can N2O cartridges be reused? No — N2O cartridges are single-use. After emptying, they must be disposed of as metal. Attempts to refill or use an empty cartridge are dangerous and prohibited.
