Reusing dry-hop hops in a boil

Post by ephemeraldog » Fri Sep 14, 2018 10:36 pm

My latest 23L brew is currently in its FV2 being dry-hopped with about 150g of leaf hops. It's smelling good, but being the Cardi smollholder that I am I got to wondering if these hops would be of any use if I used them as bittering/aroma hops. I've got an old "Winter beer" kit in my cupboard, if I made that up to 20 L or so and boiled it for an hour with the hops do you think they'd impart anything? I've nothing to lose but some of my time & a kit that would've hung out in a cupboard for another 3 years...

Interesting idea. Probably not any good as aroma hops. I'd imagine those components would be extracted by the dry hopping process but the alpha acids might well still be there waiting to be isomerised by boiling.

There is no isomerisaton going on at dry-hopping temperatures. As stated above, probably not so great of an idea to use them for aroma, but fine for bittering.

Thank you both, I'll be chucking them in later today & will post tasting notes here once it's drinkable.
