Hamish's verdict
Brew this one below 18 degrees if you can. It is a richer, maltier lager than most kits, and a clean cool ferment keeps all that malt and hop character crisp rather than muddy. Worth the patience.

What temperature should I ferment this lager kit at?
Check the yeast instructions included with your kit. Most kits designed for home use with warm-fermentation lager yeast such as Mangrove Jack's California Lager work best at 18 to 20 degrees C. If your kit includes a true lager strain (Mangrove Jack's Bavarian Lager M76 or similar), aim for 10 to 14 degrees C for the cleanest result. This is ideal for winter brewing. During warmer months a temperature-controlled fridge will be required.
How do I get my lager to come out clear?
Cold crash the fermenter to 2 to 4 degrees C for 48 hours after fermentation is complete. This drops yeast and proteins before bottling. Use a fining agent (Clearfine isinglass finings) if needed. Avoid shaking or disturbing the fermenter during bottling. Refrigerate bottles for at least a week before drinking.
What is a malt extract recipe kit?
A malt extract kit provides the main fermentable sugars in a concentrated liquid or dry form, already converted from grain at a commercial brewery. You add water, yeast, hops, then ferment. It skips the grain mashing step, which cuts brew day down to about 30 to 45 minutes while still producing full-flavoured craft beer.
What is the difference between an extract kit and a fresh wort kit?
A fresh wort kit (FWK) delivers pre-brewed, unfermented wort in a bag, ready to pour straight into the fermenter and pitch yeast. No heating required. An extract kit requires you to dissolve the malt in hot water and add hops at various stages, which takes about 30 to 45 minutes. FWKs produce brewery-fresh flavour with almost zero work.
What equipment do I need to brew this kit?
You need a 30-litre fermenter with an airlock, a hydrometer, a thermometer, a long-handled spoon, a bottle capper, crown seals, and bottles. A no-rinse sanitiser is essential. AHB stocks no-rinse sanitiser specifically for home brewing. AHB starter kits include all of this in one bundle if you are starting from scratch.
How long from brew day to first drink?
Allow 4 to 6 weeks total. Fermentation takes 7 to 14 days depending on temperature. After bottling, the beer needs at least 2 to 3 weeks to condition and carbonate. Most kits are at their best around week 5 or 6.
Can a beginner brew this kit?
Yes. Extract recipe kits are the most approachable entry point to home brewing. The malt extract is already prepared, so there is no grain mashing or complex calculations involved. Follow the step-by-step instructions included and you will produce a solid result on your first brew.
