What are the general guidelines (if there are any) for using wet hops? For example, ___ ounces of wet hops equals 1 ounce of dry hop pellets.
I use 20% ratio, or 5:1, which I believe is pretty standard from what I read here on the site. I weigh my wet hop crop prior to drying, dry them until the total weight is 20% of the original.
Easy math wise, if I had 20 Oz of wet hops, that would give me about 4 Oz. Dry hops.
As far as your hops vs. Commercial Pellet equivalent, the best I've read is making a hop tea to determine roughly the aa percentage. I estimate that my product is 30% less potent than pellet, apply my hops that way. If it's a 1 Oz charge at 60, I use 1.30 oz homegrown dried. No idea where I came up with the number, but it works for me. Edit: This usually works out to be the low end of the range listed for the hop variety. So if it's 4.5-7%, like cascade, I try to calculate it on the lower end, towards 4.5. In this case it would calculate at 4.8, which is what I would enter for my additions.
There was one thread I read that you make an initial tea and continue to dilute it with equal parts water, and each time it was diluted was roughly 1%. Didn't try it, don't know if it's true or not, but maybe someone with more know how and experience can weigh in on that procedure or debunk it.
