Thinking about using the following recipe for a wit beer. My question is, is a step mash necessary? I am not able to heat my mash tun. if a step mash is necessary, what should be the initial water/grist ratio? What ratio should i end at?
(5 gallons/19 L, all-grain)
OG = 1.050 (12.4 °P) FG = 1.011 (2.8 °P)
IBU = 20 SRM: 4 ABV = 5.0%
4.5 lb. (2.0 kg) flaked wheat (1 °L)
4.9 lb. (2.2 kg) Pilsner malt (1.6 °L)
1.1 lb. (0.5 kg) flaked oats (1 °L)
0.25 lb. (113 g) Munich malt (8 °L)
0.5 lb. (227 g) rice hulls or other natural filter
4 AAU Hallertau hops (60 mins) (1.0 oz/28 g of 4% alpha acids)
1.5 oz. (43 g) fresh citrus zest (5 mins)
0.4 oz. (11 g) crushed coriander seed (5 mins)
0.03 oz. (1 g) dried chamomile flowers (5 mins)
Wyeast 3944 (Belgian Witbier), White Labs WLP400 (Belgian Wit Ale) or Brewferm Blanche dried yeast
Step by Step
Mill the grains (including the flaked grains, but excluding the rice hulls). Mix the rice hulls into the grain post milling and dough-in targeting a mash of around 1.5 quarts of water to one pound of grain (a liquor-to-grist ratio of about 3:1 by weight) and a temperature of 122 °F (50 °C). Hold the mash at 122 °F (50 °C) for 15 minutes then raise the temperature over the next 15 minutes to 154 °F (68 °C). Hold until conversion is complete, about 60 to 90 minutes. Raise the temperature to mash out at 168 °F (76 °C). Sparge slowly with 170 °F (77 °C) water, collecting wort until the pre-boil kettle volume is around 6.5 gallons (25 L) and the gravity is 1.039 (9.7 °P).
If you have the means, I HIGHLY recommend a step mash. Especially, the mash out. The higher temp thins the wort and helps avoid the dreaded struck mash.
