Hi chaps,
Onto my second PM, this time using 2 kg of Grain. For interests sake the recipe is below (comments welcome of course), but the purpose of the post is to get some idea of what kind of extraction efficiency you think I am getting using a very elementary process of mashing.
Because I am limited on equipment and starting slowly, I did it this way; grain goes in 2 muslin bags each containing approx 1 kg each. Mash water is ratio 3 : 1 ie 6 litres of water in a 20 litre boiler which I use as a mash tun. Temperature controlled beween 65-68 deg C using probe thermometer inserted directly into the grain bag centre and checked regularly, mash time 1 hour, I occasionally agitate the bags inside the mash pot by lifting and dunking. After the mash, in a separate pot containing 3.5 litres of water at 67 deg C I soak each bag sequentially for a bout 5 minutes, then raise and drain 4 or 5 times. Then I let each bag sit in a collander for another 5 or 10 mins for all the remaining liquid to drain out, I then return the drained liquid to the mash tun, which then becomes my boiler. So I end up with about 7.5 to 8 litres in the boil.
My question is, what kind of extraction efficiency would you guess I am getting doing this hack job of a mash ? Is 60% asking too much ? I suppose I could try to calculate it but would not know where to start...
Recipe is as follows:
Malt Extract
DME 2.41 kg
Grains
UK Pale 2 Row Grain 1.0 kg
Carapils Malt 0.5 kg
Crystal Malt 0.5 kg
Hops
NZ Green Bullet Hops cones 75g (1 hour boil in a mulsin bag)
Saaz Pellets 50g (25g for 30 mins, 15 g for 15 min, 15g for 3 mins and latter two go into primary fermenter)
Saaz 12g Dry Hopping in secondary
Yeast
SafAle yeast , hydrated
Brew Temperature: 18-20 deg C
Final Volume: 24.5 litres
