Thank you
@Str8vision, I decided to try the hot extraction first. Mostly following your guidelines, down to the Busy Liz canning funnel. With a few modifications.
First, I am using a potato masher after the hot extraction to filter out the leaves. I am not bothering with a coffee filter at this stage. I will then do a 70% evaporation before freeze filtering. As you mentioned before, it helps precipitate oils out of solution if evaporated first.
After a period of winterization for 3 days, I will transfer to a cooler full of pelletized dry ice and let cool for another hour or so. I plan on placing a coffee filter in Busy Liz canning funnel, prewet with cooled 190 proof PGA to minimize filter loss. I then will place some food grade dry ice pellets directly on the filter, and pour the NET solution directly over this. The theory being that the dry ice will help prevent the coffee filter from getting clogged, capturing some of the gunk as the ethanol passes through.
It's all conjecture at this point. I am hoping the low temperature of the dry ice will help precipitate out some more gunk. Unfortunately I won't have a basis for comparison at this juncture. I am just starting out.
Final filtration will be performed at room temperature with a Whatman grade 5 cellulose filter. Again in Busy Liz canning funnel. Filter pre-wet with 190 proof PGA to minimize filter loss. My Busy Liz funnel had a dent, preventing a perfect seal, so I purchased a silicone gasket used for brewing to form a more perfect seal.
Will post results with pictures on separate thread. Will have to consider how to deal with condensation problems when photographing. Maybe a quick wipe on the canning jar glass before pics.
