BrewKeg12.5 Litre

BrewKeg12.5™ – compact 12.5L pressure brewing in stainless steel.

The BrewKeg12.5™ is a small-batch pressure fermenter designed for brewing beer and cider at home with much of the fermentation, carbonation, clarification and dispensing handled in the same vessel. For many standard WilliamsWarn recipes, the process is designed around a roughly 4–7 day brew cycle.

Why choose the BrewKeg12.5?

• Small 12.5L batches – ideal for keeping several different beers or ciders rotating.
• Pressure fermentation – ferment and build carbonation in the same stainless steel vessel.
• Sediment management – the bottom butterfly valve and sediment bottle help separate fermentation sediment from the finished drink.
• Flexible serving – dispense directly from the BrewKeg once chilled, or transfer the finished brew into bottles or a Corny keg.
• Easy to add to an existing setup – a useful way to increase brewing capacity without buying another complete system.

Buying the BrewKeg12.5 on its own

This listing is for the BrewKeg12.5 unit itself. It is a good choice if you already own the WilliamsWarn accessories you use for brewing, pressure monitoring, gas and dispensing, or if you simply want another BrewKeg in your existing setup.

If you are starting from scratch, the BrewKeg12.5 Starter Pack bundles the commonly used brewing and dispensing accessories. For a more complete setup with temperature control, refrigeration and dispensing, see the BrewKeg12.5 Complete Pack XL.

How the BrewKeg process works

1. Clean – prepare the vessel, lid, sediment bottle and beverage line.
2. Mix – add your brewing ingredients, water and yeast directly to the BrewKeg.
3. Adjust – ferment under controlled pressure, then chill and clarify the finished beer when required.
4. Dispense – serve directly from the BrewKeg or transfer to another keg or bottles.

Designed for an existing WilliamsWarn setup

The BrewKeg12.5 is particularly useful as an additional vessel. While one brew is being served from a Corny keg or another BrewKeg, you can have the next batch fermenting. It also works well for brewers who want smaller batches so they can experiment with different beer styles, hops and recipes more often.

Serving and transfer options

Once the brew is finished and chilled, you can dispense directly from the BrewKeg12.5, or free the vessel for the next batch by transferring into a Corny keg using the BrewKeg Transfer Kit (Corny Keg). If you prefer bottles, the BrewBottler allows you to counter-pressure fill carbonated beer into bottles.
