Delivery Information

Price Match

The iSi Classic Soda Siphon is a manually operated carbonation device that produces sparkling water to order. Fill it with chilled still water, fit a standard CO₂ charger, and it dispenses carbonated water on demand. There are no electrical components and no plumbing connections — it is entirely self-contained and can be positioned wherever it is needed.

In a bar or front-of-house setting, the siphon handles moderate, steady demand comfortably. The 1-litre capacity yields several servings per charge, which keeps interruptions to a minimum during a service period without requiring access to a plumbed carbonation system. It works well for sparkling water service at the table, as a bartender's tool for lengthening cocktails and spritzers, or as a practical back-bar option where a fixed carbonation unit is neither feasible nor justified by volume.

Practical advantages for operators include:

  • No plumbing or electrical supply required — flexible positioning throughout the bar or dining room
  • Stainless steel fittings support durability and straightforward cleaning between services
  • Compact footprint suits tight bar counters, service trolleys, and room service trays
  • Refillable with tap or filtered water, keeping ongoing running costs low
  • Compatible with standard iSi soda chargers, which are widely available through catering suppliers

This is not a high-volume solution. For busy cocktail bars with continuous carbonated water demand across multiple stations, a countertop or plumbed carbonation system would be more appropriate. The iSi Classic is best understood as a reliable, low-maintenance option for moderate and intermittent use.

It is well suited to small bars, hotel room service, café table service, and hospitality settings where occasional sparkling water is needed without the complexity or cost of a fixed system. Higher-volume venues should consider a dedicated carbonation unit instead.

If you are weighing this up against a plumbed alternative or want to talk through what suits your service style, we are happy to help you work it out.

Frequently asked questions

How many servings can I expect from a single CO₂ charger?

This varies depending on the level of carbonation you prefer and pour size, but a single charger typically carbonates the full 1-litre fill, which yields roughly four to six standard glass servings. For busier periods, keeping a few charged siphons ready in a bar fridge is a practical approach.

Is this suitable for a busy cocktail bar with continuous demand?

The iSi Classic is well suited to moderate and intermittent use — table service, occasional sparkling water orders, or cocktail lengthening at a quieter bar. If your operation requires a continuous and high-volume supply of carbonated water across multiple stations, a plumbed or countertop carbonation unit would be a more practical fit.

What chargers does the siphon use, and are they easy to source?

The siphon uses standard iSi CO₂ soda chargers, which are distinct from cream chargers and should not be substituted. They are widely available through commercial catering suppliers and are straightforward to keep in stock as a consumable.
