If you’re going to make your own ginger beer that’s alcoholic of course, I highly recommend using Cooper’s Ginger Beer Kit. It’s easy to make, you just need 1kg of sugar and approximately 35 bottles or a keg.
The results are a really good ginger beer that tastes just like the ones you find on the high street shelves but a lot cheaper! The alcoholic content is about 3% takes about a week in the fermenter then a further 2-3 weeks secondary fermenting in the beer bottles.
I’ve made the ginger beer in a keg last summer but not being able to easily chill the keg made the bottling a better choice.
