A lot of the recipes on Jack Keller's website require golden raisins. Does anyone think there will be a big problem if I use white grape juice concentrate instead of golden raisins? Does anyone have any experience with this?
I am a newbie and have only brewed a couple of batches of beer. I was wondering if anyone had any experience with Harpoon bottles. They say "no refill" on them. Despite this, is it safe to use them?
