iSi gas whipper with Rapid Infusion
The iSi Gourmet Whip fitted for Rapid Infusion uses a stainless-steel canister and a separate tool kit to extract botanical flavours into liquids under pressure.
A named whipper and its accessory
This entry describes a specific configuration: an iSi Gourmet Whip with the Rapid Infusion accessory, rather than every cream whipper or every rapid-infusion technique. The Gourmet Whip is a portable stainless-steel pressure canister with a fitted dispensing head and a charger holder. The separate kit adds a sieve gasket mounted on a sieve, a stainless ventilation tube, a silicone tube and a cleaning brush. Its red silicone details make the accessory easy to distinguish from the steel parts. The 2024 iSi North America catalog lists accessory 272201 for Green Whip, Gourmet Whip and Cream Profi; the earlier 2018 professional catalog records the kit for Gourmet Whip sizes of 0.25, 0.5 and 1 litre. Compatibility is model-specific: the accessory should not be treated as universal.

What Rapid Infusion does
The attachment is designed to transfer aroma from herbs, spices, fruit and other flavouring solids into a liquid. iSi lists liquids including alcohol, water, oil and vinegar. The company presents the method as a way to perform flavour extraction much faster than a steep that takes days or weeks. This is an extraction tool: it does not ferment, age, acidify or preserve the resulting liquid. Its separate venting tube and collection arrangement let the operator release pressure and direct escaping foam or liquid into a receiving vessel.

The manufacturer's method
iSi's Aromatise instructions differ from short recipes published by other cooks. The maker calls for room-temperature ingredients and directs users to respect the maximum fill line, which it connects to the pressure in the vessel. After adding the ingredients and the compatible charger, its method gently swivels the charged whipper, leaves it to rest for at least two hours, then vents it quickly with the lever. This is the manufacturer's method for its named attachment, not a universal instruction for all whippers or all recipes. Dave Arnold is credited by iSi for developing the Rapid Infusion technique; that attribution should not be confused with a claim that he invented the Gourmet Whip or a dated history of the accessory itself.

Use, limits and care
Use only a food-rated whipper, charger and attachment that the maker identifies as compatible, and follow the current instructions for that exact model. The supplied kit includes a cleaning brush, but cleaning directions for every compatible whipper are not established here. The extraction step is not a storage control. In particular, rapid infusion does not make homemade garlic or herb oil shelf-stable. Pacific Northwest Extension advises that unacidified garlic- and herb-infused oils be refrigerated for 2–4 days or frozen. That safety guidance concerns the oil, not the pressure tool, and should not be expanded into a claim about other preparations.

Where and when it is documented
The sources document a contemporary commercial product in iSi's professional catalog and current UK-language culinary material. The 2018 catalog is the earliest dated evidence gathered here for the accessory configuration; it does not establish a date or place of invention. These catalog and manufacturer pages show availability and use in the named markets, not worldwide prevalence. No traditional or historical use is claimed for this manufactured device.

Equipment details
Capacity0.25–1 L The 2722/272201 accessory is listed for Gourmet Whip sizes 0.25 L, 0.5 L and 1 L; these are supported host sizes, not one vessel's fill capacity.
PowerNot established The device uses a pressurised gas charger rather than a listed heating or electrical power source; the equipment taxonomy has no pressure-cartridge category.
How you get oneBought, manufactured A manufactured accessory intended for the compatible iSi Gourmet Whip; confirm model compatibility with the current manufacturer instructions.
CareUse the current instructions for the exact whipper and attachment. The catalog documents a cleaning brush as part of the Rapid Infusion set; the inspected material does not establish a complete cleaning procedure for every compatible model.
Made of
- Stainless steel — Gourmet Whip bottle and Rapid Infusion ventilation tube and sieve
The cited product documentation identifies these materials; this is a named iSi configuration, not a claim about every whipper. - Silicone — Rapid Infusion kit tube and seals
The iSi professional catalog identifies silicone with the tool kit.
Limits
The Rapid Infusion set is an accessory for compatible iSi Gourmet Whip models, not a universal attachment for all cream whippers.
