Add 18 litres of water to your Grainfather and insert inner basket, heat to 70°C. Add grain and stir well. Set temperature to 64°C, attach recirculation arm and recirculate for 60mins. Raise to 75°C and rest for 20 minutes. Raise basket and sparge with 10.5 litres of 75°C water to make pre-boil volume of approximately 26 litres.
HOPS FOR THE BOIL (60 minute total):
20g Columbus (15% AA) (60min boil)
1tsp Irish Moss/Whirlfloc and 1tsp Yeast Nutrient (10min boil)
30g Amarillo (8.4% AA), 20g Centennial (9.1% AA) and 600g Dextrose (5min boil)
30g Amarillo (8.4% AA), 15g Centennial (9.1% AA) and 20g Simcoe (14% AA) (0min boil)
Stir well and chill (or leave to cool) to 80°C. Add 40g Amarillo (8.4% AA), 25g Centennial (9.1%),
40g Simcoe (14%), 20g Columbus (15% AA) and leave to steep for a further 30 minutes.
Attach counter-flow chiller and chill the wort. Pump to fermenter and aerate well. Start fermentation as close as possible to 18°C*, preferably with Wyeast 1056 American Ale, 2 ets of Safale US-05, or 2 ets of Mangrove Jack’s M44 US West Coast yeast. On the 5th day of fermentation dry hop with 50g Amarillo hops for 4 days. Dry hop with 50g Simcoe hops for a further 4 days.
Tips for temperature control:
-Use the chilled water to reach a satisfactory temperature and add yeast immediately.
-Maintain a cool even temperature in the fermenter.
-Place the fermenter in a tray and wrap it in a blanket with an end in a container of water.
-Placing the fermenter on a concrete slab can also help to keep the temperature constant.
–Use a Brewing Thermostat and a fridge for optimum brewing conditions all year round.
Equipment needed for mead making:
– 4 Litre Pot
– Medium Funnel
– 2 x 5L Demijohns
– Bored Bung
– Solid Bung
-To make oak spirit use a 4-5 Litre wide neck glass jar, use around 200-300g of oak blocks or chips and 1 litre of vodka/neutral spirit. Soak for at least 14 days but the flavour intensifies the longer you leave the oak soaking. When ready, strain the oak out by passing it through filter wool in a funnel.
