Want to make your own debittered hops for lambics & such? Here's how I do it.
I take some low AA% hops & spread them on a box screen I made from 1x2" boards.
I made several frames about 18" X 36", & used aluminum window screen for the bottoms of them. Then, I took the hops, spread them on the screen, covered them with cheesecloth, and stuck them up in the rafters of my garage. I let them sit there for a good 6-8 months, then took them down & stored them in the fridge afterwards.
The hops will be brown or faded yellow when you remove them, and will be as dry as can be when they're done.
The cheesecloth prevents spiders & other bugs from making nests in the hops.
It doesn't matter what variety of hops you use, because they won't add any flavors or bitterness to the finished beer anyway.
Hope this helps someone out there.
