I followed the below 10l batch
- 1kg Maris Otter (about £1.50)
- One packet of hops (any you like - EKG, Citra, Amarillo, Galaxy, Fuggles, First gold etc) (About £3-4, but you will only use 15g of the 100g, so cost is around 50p)
- One packet of yeast, 3g dried yeast is enough. (50p ish)
Method:
1. Heat 3 litres of water to 75C in big pan.
2. Pour in the pale malt while stirring - get rid of lumps.
3. Check temp is 65-70C - adjust if necessary with cold or boiling water.
4. Wrap a thick towel round the pot and leave alone for one hour.
5. Strain into a bucket or other vessel through sieve, or colander lined with cloth.
6. Heat another 4 litres of water to 80C and add the grains back to it. Leave 10 mins, stir, and strain the liquid to your bucket. You should have about 6 litres, which will reduce when you boil it for an hour.
7. Dispose of grains, add wort to pan and bring to boil.
8. Add 5 grams of hops when boiling point is reached.
9. 55 Mins later add 5 to 10g of hops, depending on your hoppiness requirements, boil another 5 mins and switch off.
10. Cool the wort in sink, with lid on, add to sterilised FV/demijohn via sterilised sieve to catch hops, and top up the level to 5 litres if necessary. Pitch yeast at around 18 - 20C.
[Measure the amount of water added if you top up the FV, and add this amount to the sparge water next time you brew]
You should get 8 or 9 x 500ml bottles of lovely beer for about £2.50. It takes me about 3 hours start to finish, making 10 litre batches in this way (see below).
10 Litre option: You can just double all the quantities and make 10 Litres, which is what I do most of the time, it's a good amount of beer. About 18x500ml bottles, or 27x330ml bottles. You just need a 15ish litre pot.
