I saw another topic here that got me thinking on this. I'd like to buy another round of hops in bulk, and I've been using the rest of the Columbus i have in pretty much all my recent recipes to clear out the freezer. Strictly a 60 min addition, sometimes with other varieties later in the boil, sometimes not. Is there any particular reason (other than sticking to style / regional ingredients) to use one bittering hop over another? if it's going to be boiled for 60+ mins, most flavor and aroma would be gone so it shouldn't really matter, right?
