The Specific Gravity or 'SG' is a key measurement in determining when your beer or cider has completed the fermentation process and is therefore ready for bottling.
The most commonly used tool to measure this is a 'Hydrometer' which is provided in all our Starter Brewery Kits or available separately.
The gravities displayed are based on using dextrose brewing sugar, and Mangrove Jack's Pure Malt Enhancer with our pouch kits. If you use Mangrove Jack's Brew Enhancer, use the Pure Malt Enhancer as an approximate guide, your SG may be slightly higher.
Check the SG with your hydrometer, it should be within two points of the table below for two consecutive days. Once fermentation is complete, proceed to bottle your beer. For best results, ensure a minimum of 2 days infusion time between hop additions and bottling.
