High vs Low Alpha Bittering Hops
« on: December 02, 2017, 09:24:24 PM »
Hey all. Here's something I've been pondering.

A 60 minute hop addition is used to impart bitterness and doesn't do much in the way of flavour or aroma.
HOWEVER, would there be a noticeable difference between using high alpha acid hops vs low alpha acid hops for bittering, besides the varying amounts?

So for example. Let's say you wanted to get 40IBU out of your 60min hop addition, and your two options are a small amount of something like Magnum, or a large amount of something like Hallertau (comparitively). If both amounts end up as 40IBU, and are used as a 60min addition for bittering, would the final product be much different?

It seems common sense to use high alpha hops for bittering, to save money, but is there potentially some sneaky extra flavours getting in there that one could potentially miss out on? I feel I'd use high alpha anyway, but it's been on my mind.

Cheers!

Interesting, I have actually never thought about it, depending on what im brewing I mostly still use a high alpha hops like pacific gem 14% - 16% alpha for just bittering, but from my own experience I know it does give a flavor and aroma even from the bittering addition so it might be something to think about for sure.

I would think you still get a little flavor from the bittering hop, not a lot because of the 60-90min boil driving it off.  I imagine you might get a little more flavor from the lower alpha hop then the higher alpha. just because you are adding more hops. Sounds like an experiment in the future.
I may try this on my next Dead Ringer IPA and split the boil
swap out the centennial hop addition for a magnum addition @60min on one boil.
of course i need to figure it out in my software, shouldnt take but a minute or two ;)
i have a few other brews i need to do before this.
