I'm going to do an extract brew and I intend to use 1 lb of 40 L crystal malt to improve mouthfeel and colour. I will probably also add about 2 tbsp of black patent malt to darken it a bit more.
When I steep the grain, should I do it in a grain bag in the whole 6 gallons I intend to boil or is more/less effective to do it in a smaller volume so I can control the temperature better. I'm thinking maybe a gallon of water at 150-155 degrees F? How long would you steep it for? Or, just throw the grain bag in and let it sit in as it heats up and pull it out before it boils?
Is 1 lb of crystal malt enough to really make an impression in 5 gals of beer? If not, how much for next time?
