What Is SmartWhip Used For? Every Use Explained

Quick answer: SmartWhip is a large cylinder of food-grade nitrous oxide (N2O) used to charge cream whippers. Chefs, bakers and bartenders use it to make whipped cream, sweet and savoury foams, mousses, sauces and fast flavour infusions. One 640g cylinder holds roughly the same gas as 80 standard 8g cream chargers, and a pressure regulator lets you set exactly how much gas goes into each whipper.
The cylinder doesn’t whip anything on its own. It supplies the gas, and your cream whipper does the rest. We stock both 640g cylinders, Original and Silver, in our SmartWhip UK range.

The 7 main uses of SmartWhip
| Use | What you can make | Where it’s used |
|---|---|---|
| 1. Whipped cream | Toppings for cakes, desserts, hot chocolate and coffee | Cafés, bakeries, dessert shops, home kitchens |
| 2. Sweet foams | Fruit, chocolate or coconut foams | Dessert bars, restaurants |
| 3. Savoury foams (espumas) | Cheese, potato, herb or seafood foams for plating | Restaurants |
| 4. Mousses | Light mousses without long whisking | Pastry kitchens, caterers |
| 5. Sauces and soups | Light, aerated warm or cold sauces and soups | Restaurants, caterers |
| 6. Fast infusions | Flavoured spirits, oils and syrups | Cocktail bars, restaurants |
| 7. Drinks and cocktails | Foam toppings for cocktails, mocktails and coffee | Cocktail bars, coffee shops |
1. Whipped cream
This is the main use. N2O dissolves into the cream under pressure. When you press the lever, the gas expands and the cream comes out light and whipped in seconds. A sealed whipper also lets you make cream ahead and serve it through a busy shift.
2. Sweet foams
Chefs turn fruit purées, chocolate or coconut mixtures into light foams for desserts. Many recipes need a little gelatine or another stabiliser to hold their shape. SmartWhip publishes a vegan coconut foam recipe as one example.
3. Savoury foams (espumas)
An espuma is a light foam made from a flavoured liquid, such as cheese, potato or a seafood bisque. Restaurants use them to add flavour and texture to a plate without adding weight.
4. Mousses
A whipper can aerate a mousse base in seconds, with no folding or long whisking. You also get the same texture every time, which helps when you’re plating in volume.
5. Sauces and soups
Whipper maker iSi says its Gourmet Whip can make “warm and cold sauces, soups, espumas and desserts”. Only use hot mixtures in a whipper that’s made for hot use, and follow its temperature limits.
6. Fast infusions
Pressure from N2O pushes flavour from herbs, fruit or spices into a liquid. iSi says this can cut infusions that “used to take days or even weeks” down to “a fraction of the time”. Bars use it for flavoured spirits and syrups. Kitchens use it for oils and dressings. Read more in our guide to advanced infusion in commercial kitchens.
7. Drinks and cocktails
Bartenders use SmartWhip for foam toppings on cocktails and mocktails, and coffee shops use it for cream and cold foam. It adds texture on top of a drink. It doesn’t make the drink fizzy (see “What SmartWhip is not used for” below).
SmartWhip’s official recipe categories
SmartWhip’s own website lists more than 140 recipes made with a cream dispenser, sorted into 10 categories. It’s a good guide to how far the uses go beyond whipped cream:
| Category | What it covers |
|---|---|
| Desserts | Whipped cream, dessert toppings and fillings |
| Mousses | Sweet and savoury mousses |
| Foams | Sweet and savoury foams and espumas |
| Sauces | Light, aerated sauces |
| Soups | Aerated soups and soup foams |
| Meals | Foams and sauces for main dishes |
| Salads | Foams and dressings for salads |
| Finger food | Small bites and canapés |
| Drinks | Cocktails, mocktails and drink toppings |
| Rapid infusion | Flavoured spirits, syrups and oils |
Examples on the site include a bisque foam, a coconut mocktail and a linguine with two tomato textures.
Why chefs use SmartWhip: control over texture
This is the part most guides miss. With 8g chargers, you add gas one full charger at a time. SmartWhip connects through a pressure regulator, so you can set the pressure yourself.
SmartWhip says chefs and bartenders use it “to get exact amounts of pressure for achieving the desired texture and intensity” of anything that comes out of a cream dispenser. It also talks about “the relation between foam density and pressure”.
In practice, that means:
- Lower pressure for softer, lighter foams
- Higher pressure for firmer foams and thicker mixtures
- The same setting every time, so a dish comes out the same on every shift
Make small changes and test as you go. Always stay within the limits of your whipper and regulator.
What was SmartWhip made for?
SmartWhip says it was the first company to market a large disposable cylinder filled with nitrous oxide. It was made so that kitchens and bars could charge cream dispensers from one large cylinder, with controlled pressure, instead of opening box after box of small 8g chargers.
Who uses SmartWhip?
| Business | What they use it for | Why a large cylinder helps |
|---|---|---|
| Coffee shops | Cream toppings, cold foams | Many small top-ups through the day |
| Bakeries and dessert shops | Cream for cakes, desserts and shakes | High volumes of cream |
| Restaurants | Espumas, mousses, sauces, soups | Several whippers in use during service |
| Cocktail bars | Foam toppings, infused spirits | Fast infusions and consistent foams |
| Caterers and events | Desserts and toppings in bulk | Less kit to carry than boxes of chargers |
| Home cooks | Whipped cream and desserts | Only worth it if you whip cream often |
How much gas does each whipper need?
iSi advises 1 charger for a 0.25L or 0.5L whipper, and 2 chargers for a 1L whipper. A standard charger holds 8g of N2O. Here’s what that means for one 640g SmartWhip:
| Whipper size | Gas per fill (iSi guidance) | Approx. fills from one 640g SmartWhip |
|---|---|---|
| 250ml (0.25L) | 1 charger (8g) | about 80 |
| 500ml (0.5L) | 1 charger (8g) | about 80 |
| 1 litre | 2 chargers (16g) | about 40 |
These are estimates based on gas weight. With a regulator you may use more or less, depending on the pressure you set and your recipe.
Need a whipper? We stock a 250ml cream whipper for home and light use, and a 1L cream whipper for cafés and kitchens.
The SmartWhip system: what each part does
SmartWhip describes a full system made up of these parts:
| Part | What it does |
|---|---|
| N2O cylinder | Holds the food-grade nitrous oxide (E942) |
| Pressure regulator with gauge | Sets the working pressure and helps prevent wasted gas |
| Filling hose | Connects the regulator to the cream dispenser |
| Custom adapter | Screws onto your dispenser so it can be charged from the cylinder. SmartWhip says it works with any brand, including iSi and Mosa |
| Wall mount (optional) | Holds the cylinder on the wall for faster, safer charging |
| Cream dispenser | Holds your cream or recipe. Sold separately |
SmartWhip says its regulator comes with the custom adapter, and has a pressure relief valve. Always follow the instructions for each part and check every connection before you open the valve.
What SmartWhip is not used for
- Fizzy drinks. SmartWhip contains N2O, not CO2. iSi says N2O chargers are for “cream, espuma and mousse”, while CO2 is for “carbonated sodas, drinks”. Don’t use SmartWhip in a soda siphon.
- Cars. Car nitrous kits are a separate automotive product. SmartWhip is food-grade N2O sold for kitchen use.
- Inhaling. It’s dangerous, and since 8 November 2023 it’s illegal to have nitrous oxide if you intend to inhale it. See Is SmartWhip legal in the UK?
- Whipping on its own. The cylinder only supplies gas. You still need a regulator, hose, adapter and cream whipper.
SmartWhip Original vs Silver
Both are used for exactly the same things, because both hold 640g of food-grade N2O. The difference is the cylinder:
- SmartWhip Original: a steel cylinder. See the SmartWhip Original 640g.
- SmartWhip Silver: SmartWhip says it’s made entirely from aluminium, making it its most lightweight cylinder. See the SmartWhip Silver 640g.
SmartWhip says Silver works with all parts of the SmartWhip system. Compare both in our SmartWhip UK range.
SmartWhip or 8g chargers?
| SmartWhip (640g) | 8g cream chargers | |
|---|---|---|
| Gas | Roughly the same as 80 chargers | 8g each |
| Pressure | Adjustable with a regulator | Fixed, one charger at a time |
| Best for | Cafés, bars, restaurants, caterers | Home use, low-volume kitchens |
| Extra kit | Regulator, hose and adapter | None; fits a standard whipper |
| Waste | One cylinder to recycle | Many small cartridges |
If you only whip cream now and then, 8g cream chargers are simpler. If you fill whippers many times a day, a cylinder saves you changing chargers. Compare other large cylinders in our 200g to 670g cylinders and N2O cylinders ranges, or browse all cream chargers.
Tips for better results
- Pick the right cream. iSi says the best results come from cream with 30 to 36% fat. Check the label.
- Keep it cold. iSi advises chilling UHT cream in the fridge for 24 hours before use.
- Don’t overfill. Stop at the maximum fill line on your whipper.
- Shake, but not too much. iSi’s Gourmet Whip guide says to shake “at least 6 times”. Shaking a lot more after that can reduce what you get out.
- Hot recipes need the right whipper. iSi says to keep its Gourmet Whip warm in a bain-marie at no more than 165°F (about 74°C).
- Store cylinders safely. Keep them upright in a cool, dry place, away from heat and direct sunlight. When empty, see how to dispose of N2O canisters safely.
Is SmartWhip legal to use in the UK?
Yes, for food and drink. The government lists catering, “as a whipped cream propellant”, as a legitimate use of nitrous oxide. The gas is also an approved food additive, E942, on the Food Standards Agency’s list.
Since 8 November 2023, nitrous oxide has been a Class C drug if you have it to inhale. For the full rules, read Is SmartWhip legal in the UK?
FAQs
Is SmartWhip only used for whipped cream?
