so the boil gravity will be 1049 but i have not added the can of extract will that stuff up the IBU's at the end
When the can is added, the boil gravity goes right up, which lowers the (edit: further) utilisation of the hops...(edit: but the IBU that has already been extracted, stays extracted)....but if its added right at the end, ie last couple of minutes, or even at flame out, it doesn't have time to make a difference. For tins, the extract will be sterile inside the can anyway, so it can go in at flameout....dry extract is not in sterile containers, so is best to boil for at least a couple of minutes. But as I said, by that time, the difference it will make is sfa.
