How to Bottle Home Brew Beer
Bottling is one of the most satisfying moments in the home brewing process — the point at which your fermented beer is transformed into proper, shareable bottles of homemade ale. Done correctly, bottling produces consistently carbonated, clear, great-tasting beer. Done carelessly, it can result in flat beer, over-carbonated bottles, or contamination. This guide walks you through everything you need to know to bottle your homebrew confidently and consistently.
What You'll Need
To bottle your homebrew you'll need: clean, sterilised bottles (brown glass is ideal to protect against UV light); a bottle capper and crown caps; a siphon tube; a bottling wand (a spring-loaded tube that fills bottles from the bottom up, minimising oxygen pickup); and priming sugar or carbonation drops for natural carbonation. Alternatively, swing-top (Grolsch-style) bottles eliminate the need for caps and a capper altogether.
Priming for Carbonation
Natural carbonation in bottle-conditioned homebrew is achieved by adding a small amount of fermentable sugar before bottling, which the remaining yeast ferments to produce CO2 in the sealed bottle. The standard rate is approximately half a teaspoon of white sugar per 500ml bottle, or one Coopers Carbonation Drop per 500ml bottle for a consistent, mess-free alternative. Add the sugar directly to each bottle or dissolve the total amount in a small quantity of boiled water and add to the bottom of your bottling bucket before siphoning.
The Bottling Process
Sterilise all bottles, the siphon, and the bottling wand. Siphon the finished beer gently into your bottling bucket (if priming with dissolved sugar) or directly into bottles. Fill each bottle to within 2cm of the top, cap immediately, and store upright at room temperature for 7–14 days to allow carbonation to develop. Then move to a cool place for storage and conditioning. The longer you leave it, the better it gets — most homebrew improves significantly between 2 and 8 weeks.
