LOL, I just got rid of all my old trim. You're right, it does build up after a while. I did have a freezer full a few years back but this time it was only about 15 or 20 ounces. Made some decent sift. I definitely prefer the yield from bubble over dry sift. Those first few runs come out just like fudge. LOL
I have been reading more about the awful flavor of cannabis. More than a few posts said that ginger is a good balance. Mrs. Hackerman always keeps fresh ginger root around so next time I decarb rosin, I might grate a tiny bit of ginger and put it in with it when I decarb it. That would seem the best time to get the most benefit and the least aftertaste of ginger in the finished product (unless I make ginger snaps LOL).
Another way to look at this is logically. My favorite method. LOL
Cannabinoids and terpenes, that what we are dealing with. No leaves, sift or anything else. Just rosin so it's mostly cannabinoids and terpenes.
Cannabinoids have no taste or odor so those are out. That leave terpenes.
The most predominant terp in cannabis is Beta Myrcene. This is a giant contributor to the aroma and this terp is often used in the perfume industry. I know perfume does not taste great. LOL Smells great tastes poo poo. Maybe that's a contributor to the bad tast of pot.
Beta Myrcene is also found in mango, hops, lemon grass, East Indian bay tree, and verbena. So, I'll look for spices or herbs that balance those foods and.... maybe I'll hit a match.
There seem to be so many different terps in Cannabis but I'm guessing that the top 5 will be 90% of the total amount. We'll see if that's true.
I found a nice list of terps at another site that I am going to post here for reference.
