Tremendous responses! Thanks for everything you guys are saying!
I've heard about Simcoe, and it's been recommended, but my local homebrew store doesn't have any in stock. I love the idea of going for tips specifically -- and I was just using Pine as a catch-all for that type of tree, though spruce was my (albeit unvoiced) intention. I live in Colorado, and my intent was to head up to the hills and snip some real tips and use those, but obviously the time of year has some effect. Does anyone think that the time of year will ruin it, or can I just boil them for an hour and roll with that? And to be clear (I'm a rookie, sorry) you're saying boil them for an hour, and then proceed with the rest of the recipe in that boil, right?
Also, the suggestion of yarrow is VERY interesting, something I'm definitely going to read up on before I brew this weekend.
Thanks for some amazing suggestion!
