We are currently brewing out 7th extract kit from Midwest supplies ( killians mock) as reading the instructions we noticed these particular instructions say when finished steeping the grains at 155 to immediately add the lme, on all previous brew days we have brought the wort to a boil after steeping grains before adding the lme, is this a issue that we brought the wort to a boil before adding lme? And if so why. Thanks!
