Isn’t adding hoops to the mash essentially First Wort Hopps? That’s a legit, if maybe gimmicky, thing, right?
The only caution I’d add to the discussion of hops in the mash, is to make sure when finished that the spent grains are protected from dogs. Dogs usually don’t like the smell of hops, but when sweetened up with spent grain they can end up consuming them. Hops, even spent hops, can be very toxic to dogs, and it’s weird because one day it may not effect the dog at all, but another day a lesser amount can be fatal. If you have a dog that likes to get into the garbage/mulch it may be better to just avoid the technique.
