I went to measure my grain out today for the first time on a new recipe and put a 3lbs bag of Mutons Extra Light I had just bought from LHBS and it weighed only 1lbs. The grains I bought weighed just what the package said. Am I missing something?
You can add extract after fermentation has started. Leave a half gallon space. Buy some more extract, boil with half gallon of water for 10 minutes, cool and add to fermenting wort/beer.
I am just at the grain steeping stage, I wonder if I can keep it until tomorrow and go to the LHBS and get the right amount - I have not added the DME yet
