Expert Review and  Insights

The iSi Classic has a reassuring heft and  a timeless look that just feels right on a professional back bar. It’s not about high volume; it’s about craft. The quality of the carbonation is noticeably finer and  more vibrant than bottled soda, which really makes a difference in delicate cocktails like a Tom Collins or a spritz. It’s a tool for bartenders who care about the details.

  • Presentation King: The polished look and  classic design make it a real showstopper.
  • Manual Process: Requires shaking and  reloading, which can slow workflow during peak rushes.

Case Study: Real Business, Real Results

The speakeasy-style 'Clockwork Door' in Bath was looking for a way to enhance the authenticity of their classic cocktail menu and  reduce their significant glass bottle waste. They switched from buying cases of sparkling water to using two iSi Classic Soda Siphons at their main bar station.

"The siphons are more than just functional; they're part of the show. Customers love seeing us make the soda fresh for their drinks. The carbonation is sharper and  lasts longer, and  our gin and  tonics have never been better."

Eleanor Vance – Bar Manager

The change has improved the quality of their signature fizzy cocktails and  cut their monthly bottle recycling load by over 70%.

Installation and  Maintenance Guide

Setting It Up

  • For the best fizz, always start with fresh, very cold water (ideally refrigerated for a few hours).
  • Fill the bottle only to the maximum fill line indicated on the side to leave space for the gas.
  • Insert one CO2 charger into the holder and  screw it onto the siphon head until you hear the gas fully release.
  • Shake the siphon vigorously around 5-10 times to help the CO2 dissolve completely into the water.
  • For best results, let the charged siphon rest in the fridge for at least 10 minutes before dispensing.

Keeping It Going

  • Always depressurise the siphon completely by pressing the lever before attempting to unscrew the head for cleaning.
  • Hand-wash all components with warm, soapy water after use. This model is not dishwasher safe.
  • Use a small brush to occasionally clean the dispensing nozzle to prevent any mineral build-up.
  • Store the siphon in a cool, dry place. For long-term storage, leave the head unscrewed.

Buying Guide: Choosing the Right Soda Siphon

Not sure which soda maker fits your bar? Here’s a quick guide to help you decide.

Consider Capacity vs. Volume

A 1L siphon like this is perfect for craft cocktails and  table service. For very high-volume bars needing constant soda, a larger, plumbed-in carbonator system might be more efficient.

Material Matters

Look for robust materials. The stainless steel fittings on this iSi Classic are designed for commercial durability and  frequent use, unlike cheaper, all-plastic consumer models.

Ease of Use and  Cleaning

A simple screw-on charger mechanism and  easy-to-disassemble parts are crucial for a fast-paced environment. Quick rinsing between refills keeps service flowing smoothly.

Style and  Aesthetics

Think about your bar's decor. A soda siphon can be a customer-facing piece of equipment, so a classic design like this one can enhance your brand's image and  atmosphere.

Sustainability and  Cost

A reusable siphon dramatically reduces single-use bottle waste. While there's an initial investment, the long-term saving on bottled water and  your improved green credentials are significant.

Frequently Asked Questions

Q: How many drinks can I make with one 1L charge?

A: A fully carbonated 1L siphon will provide approximately four to five 200ml servings of soda water, perfect for cocktails or small glasses.

Q: What is the best way to get the fizz-iest water?

A: The key is temperature. Use filtered water that has been chilled in the fridge for several hours. The colder the water, the more CO2 it can absorb.

Q: Can I carbonate juice or other liquids?

A: No, this commercial soda water dispenser is designed for use with plain water only. Using sugary or pulpy liquids can clog the mechanism and  cause dangerous pressure build-ups.

Q: Is the iSi Classic CR708 dishwasher safe?

A: No, to protect the finish and  the integrity of the seals, the siphon and  its parts should be hand-washed only with warm water and  mild detergent.

Q: What are the main components made of?

A: This model features a high-quality bottle with durable, commercial-grade stainless steel fittings and  head, ensuring longevity.

Q: How long will the water stay fizzy inside the siphon?

A: If you store the charged siphon in the fridge, the carbonated water will remain fresh and  fizzy for up to two or three days.

Q: What type of CO2 chargers does it require?

A: It uses standard 8.4g non-threaded CO2 chargers, which are widely available for commercial bar use (our code GH056).

Q: Does shaking it really make a difference?

A: Yes, absolutely. Shaking the siphon vigorously after charging is essential as it helps the CO2 gas dissolve fully into the water for maximum fizz.

How On-Demand Carbonation Elevates Your Drinks

Ever wonder why a drink made with a soda siphon tastes so much crisper? It's all about the science of on-demand carbonation. Think of it like having a miniature fizzy drink factory right in your hand. When you screw a CO2 canister into the iSi siphon, it injects pure, pressurised carbon dioxide gas directly into very cold water. This pressure forces the gas to dissolve, creating thousands of tiny, sharp bubbles.

Unlike pre-bottled soda that can lose its fizz over time, this process happens moments before you serve. The result is a more intense and  longer-lasting effervescence, often described as a 'finer' bubble. For a cocktail, this means the drink stays lively from the first sip to the last, and  the crispness cuts through sweet or strong flavours perfectly. It gives the bartender absolute control over the freshness and  quality of a fundamental ingredient.

Who Should Buy This?

  • Boutique Cocktail Bars: Perfect for crafting signature highballs and  spritzes with superior, freshly-made soda water.
  • Gastropubs & Inns: Elevate your table water service, offering a premium and  sustainable alternative to bottled sparkling water.
  • Luxury Hotels: An elegant addition for room service trolleys or the minibar to provide a touch of class.
  • Artisan Cafés: Create authentic Italian sodas, sparkling teas, or add a fizzy twist to cold brew creations.
