I am getting started with my first brewing experience, I have some doubt in my mind, and I was hoping someone could clear this up for me once and for all.
I have seen a lot of beer recipes that leave some vagueness to the hop addition timing, and the length of mashing out.
How long do you steep the grains/extract/sugar if the recipe doesn't say?
When a recipe lists some hops, and then a time, is that the time that passes after the wort starts boiling to add the hops, or is that the amount of time to leave the hops in?
Should I always assume a 90 minute boil?
