Yields are low, around 4%, when washing bud with 200 proof ethanol, distilling off the ethanol, and vacuum purging the slurry to yield a shatter.
The bud is whole bud that has been freeze dried and kept in a -86 C freezer.
Ethanol is kept in -86 C freezer as well.
Bud steeps in sub-zero ethanol for 30 minutes and color of solution is yellow-gold. Looks great and excellent clarity.
Problem is the find yield of the shatter was 5.7 grams out of 153 grams of the above mentioned bud. I don't know the THC percentage of the bud, but it was sun grown and possibly 15%.
I was hoping my yields would be closer to 10% because anything less is just not worth it.
Any ideas?
