I've read that Dry Hops only release the aroma and some flavoring properties. All bittering properties are left behind.
I'm curous do you think one could expect full bittering properties from the re-use of the Dry Hops if I froze them post Dry Hopping some beer and brewing my next batch?
1) I wouldn't freeze wet hops - definitely not what you want.
As for re-using dry hops, a few breweries did play around with this concept with varying degrees of success during last year's worst part of the hop crisis. They all seemed to agree though that through analysis that they lost about 30% of the bittering potential from previously used dry hops....
Now, if Liebs were here, I'd expect a vitrolic rant about the dangers of re-using hops.
