A number of my favorite recipes I've brewed over the years call for Hallertauer (Hallertau) hops.
Guess I missed something or was sleeping ;-) as, apparently, the names have changed.
Ditto! This is brand new news to me.
So I wonder WTF kind I have been growing in my backyard for 15 years. No way of knowing I guess.
Certainly there must be some formal article(s) out there about this. Whoever knows, please share.
A recipe that just says Hallertau is lazy recipe writting.
This irks the hell out of me. It seems that what really happened is that tens of millions of brewers have been left in the dark for however long as this "fact" has been known by a few.
As far as I have known, my understanding was that there was the original hop known as Hallertauer Hallertau, and all the others were derivatives of either that one or Mittelfrueh.
