Choosing a Home Draught Beer System for Drinks on Tap at Home

Setting up a home draught beer system lets you serve fresh, pub-quality pints at home, whether you buy commercial kegs or keg your own homebrew. The right system depends on your space, budget, and how often you entertain. This guide covers the main options, key components, setup costs, and serving tips to help you choose.

What Is a Home Draught Beer System?

A home draught beer system dispenses beer from a keg under pressure, keeping it carbonated and chilled. The core components include a keg, a CO2 cylinder with a regulator, beer and gas lines, a tap or faucet, and a cooling method. The most common all-in-one solution is a kegerator—a refrigerator designed to hold a keg and dispense beer through a tower tap. Alternatively, you can build a system using a chest freezer with a temperature controller (often called a keezer) or convert a spare fridge. A home brew draft beer system typically refers to a setup for kegging homebrewed beer, using corny kegs or similar.

Types of Home Beer Tap Systems

There are several options, each with different costs and capabilities:

• Kegerator: A purpose-built appliance with a built-in cooling unit, tap tower, and room for one or more kegs. Most models accept commercial Sankey kegs, and with a conversion kit, corny kegs for homebrew.
• Keezer (chest freezer conversion): A chest freezer fitted with a temperature controller and a wooden collar to mount taps. It offers excellent insulation and can hold multiple kegs, but requires DIY work.
• Countertop or mini dispenser: Small units using 5-litre mini kegs or growlers, ideal for occasional use and limited space. They chill and dispense but may require proprietary kegs.
• Party pump: A simple hand pump that uses air to push beer from a keg. It does not require CO2, but the beer will go flat within a day because air oxidises it. Best for a single event.

For most UK homes, a kegerator size that holds a 30-litre or 50-litre commercial keg, or two 19-litre corny kegs, is a good balance. Check UK availability of keg sizes: many breweries supply 30-litre or 50-litre kegs, while 5-litre mini kegs are widely sold.

Understanding Key Components

Keg Couplers and Compatibility

Commercial kegs use different fittings depending on the brewery and country. In the UK, most use the Sankey 'S' coupler, but some European imports may need 'A' or 'M' couplers. Always verify the coupler type before buying a keg. Homebrew kegs (corny kegs) use ball-lock or pin-lock posts, which require different quick disconnects.

CO2 Regulators and Gas Cylinders

The CO2 regulator reduces the high pressure from the gas cylinder to a safe serving pressure, typically 10–12 psi for most ales and lagers. Most systems use a single-gauge regulator, but a dual-gauge shows both cylinder pressure (how much gas remains) and output pressure. Gas cylinders come in various sizes; a 6.35 kg cylinder is common for home use and lasts for several kegs. Ensure you can exchange or refill your cylinder locally—many homebrew shops and gas suppliers offer this.

Beer Cooling

Beer must be kept cold (2–8°C depending on style) to prevent foaming and maintain freshness. Kegerators and keezers have built-in cooling; if you use a converted fridge, ensure it can hold a steady temperature. For direct-draw systems (where the tap is close to the keg), the entire keg is chilled, which is efficient. Long-draw systems with remote taps require additional cooling for the beer lines, which is expensive and rarely used at home.

Home Draught Beer System UK: Costs and Setup

Budget is a major factor. Here is a comparison of typical equipment costs and kegerator setup cost in the UK:

Installation costs for a kegerator are minimal—you just plug it in and connect the lines. A keezer build requires some DIY skills and time. Kegerator setup kits often include a regulator, lines, and tap; ensure the kit matches your keg type. Some retailers offer complete kegerator setup kits for homebrew corny kegs.

Choosing Your Beer and Serving It Well

Your home draught system lets you serve commercial kegs or your own homebrew. Consider the following:

• Beer style and temperature: Lagers and pilsners are best at 2–4°C, ales and stouts at 8–12°C. A kegerator with adjustable temperature can serve both, but you may need to compromise if you have multiple kegs.
• Carbonation level: Different styles require different CO2 volumes. Ales often need 1.5–2.0 volumes, lagers 2.2–2.6. Use a carbonation chart to set your regulator pressure based on temperature and desired carbonation.
• Glassware: Use clean, beer-clean glasses (rinsed with water only, no soap residue) to ensure good head retention. A pint glass or tulip works for most styles; a pilsner glass showcases clarity and carbonation.
• Food pairings: A crisp pilsner pairs with fish and chips or spicy food; a hoppy IPA complements burgers and strong cheese; a stout goes well with chocolate desserts or oysters. For alcohol-free options, many UK breweries now sell alcohol-free beer in kegs or you can keg your own alcohol-free homebrew.

Regular beer line cleaning is essential: clean lines every two weeks or between kegs using a line cleaning solution. This prevents off-flavours and microbial growth.

Homebrew Kegging: Taking Your Beer to the Next Level

If you brew your own beer, homebrew kegging saves time compared to bottling and gives you more control over carbonation. You will need corny kegs, a CO2 system, and either a kegerator with a conversion kit or a keezer. The process:

1. Transfer your fermented beer to a sanitised corny keg, leaving behind sediment.
2. Seal the keg and purge oxygen by filling the headspace with CO2.
3. Set the regulator to the desired pressure and either force carbonate at high pressure (30–40 psi for 24–48 hours) or set to serving pressure and wait a week.
4. Chill the keg to serving temperature before dispensing.
5. Connect the beer line to the keg post and tap; pour and enjoy.

Kegging also allows you to serve alcohol-free homebrew by using a low-alcohol recipe and force carbonating as usual.

Final Thoughts

A home draught beer system is an investment in convenience and freshness. Whether you choose a simple mini keg dispenser or a full multi-tap keezer, the key is matching the system to your drinking habits, space, and budget. Remember to factor in ongoing costs like CO2 and cleaning supplies, and always drink responsibly. With the right setup, your next gathering can feature perfectly poured pints from your own home draft beer dispenser.
