How to Use a Home Brew Beer Kit — Step by Step Guide
Share
How do you use a home brew beer kit?
Using a beer kit is a six-step process: sterilise your equipment, prepare the wort (dissolve the kit extract in water), pitch the yeast, monitor fermentation for 7–14 days, confirm completion with a hydrometer🛒 Buy, then bottle with Carbonation Drops🛒 Buy and condition for two weeks. Full details below.
Step 1: Gather your equipment
You'll need a 25-litre fermentation bucket with tap🛒 Buy, a bubbler airlock🛒 Buy, a hydrometer🛒 Buy, a thermometer, a long-handled spoon, and either bottles🛒 Buy and a capper🛒 Buy or a pressure barrel. See our full home brew equipment range.
Step 2: Sterilise everything
This is the most important step — contamination ruins more home brews than any other cause. Dissolve Young's Steriliser🛒 Buy in water and thoroughly coat every surface that will touch your beer. Rinse and drain. Read our complete sanitation guide for more detail.
Step 3: Prepare the wort
Stand your kit can in warm water for a few minutes to soften the extract. Pour into the fermenter, add 1.5 litres of boiling water and stir well. Add Brew Enhancer 2🛒 Buy (much better than plain sugar — see our Brew Enhancer guide) and stir again. Top up to 23 litres with cold water and check the temperature is 18–24°C.
Step 4: Pitch the yeast and ferment
Sprinkle the yeast over the wort surface, fit the lid and airlock (half-filled with water), and place somewhere stable at 18–24°C. Fermentation begins within 24–48 hours. Leave undisturbed for 7–14 days. Want to upgrade the aroma? Read our dry hopping guide.
Step 5: Confirm fermentation is complete
Fermentation is complete when two hydrometer🛒 Buy readings taken 24 hours apart are identical. Most kits finish around 1.006–1.010 SG. Never rush this — see our FAQ for what happens if you bottle too early.
Step 6: Bottle and condition
Siphon your beer into sterilised bottles, add one Carbonation Drop🛒 Buy per 500ml bottle for natural carbonation, cap with Crown Caps🛒 Buy using your Beer Capper🛒 Buy, and store at room temperature for at least two weeks. See our conditioning guide for exactly how long each style needs. Browse all beer kits and equipment at BrewCo UK.
