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.
Note: Not all varieties are sold in all markets.

Also Note: ABV stated on the pouch kit is based on using dextrose, unless there is no gravity reading for dextrose in the tables above - those kits are designed to be used with Pure Malt Extract only and therefore the ABV is determined based on the use of Pure Malt Extract.

*Please Note: that when using standard table sugar rather than dextrose with our Cider kits the OG will be 3-5 points higher than the dextrose figures. With Table sugar its hard to give a definitive figure but use this as a guide.
The cider kits are based on the same SG contribution, so the enhancers are 1.2kg which provides the same SG as 1kg dextrose
