I do high gravity beers – sometime as much as 18 pounds of grain. How many gallons is your mash tun and will it support this?
The BREWTREE mashtun is 15 gallons. A normal gravity beer (approx 1.056 O.G.) uses 8LBS of base malt per 5 gallon batch, and then you would have to add your adjuncts. If you were doing a full 15 gallon batch, you would use 24 LBS of BASE malt, and probably about 1-3LBS of flaked barley (for head retention), plus your specialty malts. I believe the mashtun can hold well over 35LBS…Our chocolate stout recipe that comes with the system uses 33 LBS of grain, and I know there is still room in the mashtun.
