Two Ginger Beer Brewing Kits. Each ginger beer brewing kit can be used to develop a ginger beer culture (sometimes called a “ginger beer plant”) that should grow and grow. Each pack contains: 125g Fairtrade ginger and yeast; this is enough for several 8 litre batches of ginger beer. You will also need to buy 1 kg of sugar and 2 lemons. Old Hamlet Wine & Spice Ginger Beer Kits are made in the UK by Steenbergs, the herbs and spices specialists.
