You know, I can't help thinking that this farmer (and others in his situation) would pay handsomely for a brewer to categorically prove that the mandarin flavor is good, and the onion/garlic thing can be avoided, and how it can be accomplished.
The point is, this (quite large) field is costing him a lot of money being out of production, and it will take even more money to re-trellis it for another variety.
C'mon lottery! Daddy needs a hop research lab.
