1. A day before, place 10-15 litres of water in closed containers in a fridge and chill.
2. Steep Grains for 20-30 mins with 1.5 litres of hot tap water (not boiling).
3. Strain liquid into a large saucepan. Rinse grain with another 1 Litre of hot tap water into the saucepan, and discard grain.

5. Add 15g Centennial hops.
6. After 30 minutes add 30g Cascade hops and allow to boil for a further 10 minutes.
7. At the end of the 40 minutes, turn off the heat and add 15g Centennial and 15g Cascade hops.
8. Add the rest of the malts and stir to dissolve. Place the saucepan in a sink of cool water for 10-15 minutes.
9. Pour the contents of the saucepan into the fermenter, and top up to 23 litres with chilled and tap water to reach a starting temperature of 12-15°C if using the Saf yeast or Wyeast, If using the Californian lager increase temperature to 18-22°C. Stir vigorously to aerate.
10. Add yeast and ferment as close as possible to 20°C. 4 days prior to bottling/kegging, add 30g Centennial hops to fermenter. Bottle or keg when gravity is consistent over two days.

With 10 minutes left of the boil, it is often desirable to add whirlfloc or irish moss to help clear your wort.
