I was wondering if anyone has tried a dual stage extraction or mixed a cold maceration with a warm extraction? I am asking because from all my reading cold and warm extractions each seem to pull different flavors from the tobacco. Mixing NET extracted both ways or actually doing a dual extraction on the same batch of tobacco would seem like it would give the complete flavor palette.
Currently deployed so can't test this yet but I was thinking of trying this method when I get home in a few months.
1. Mix tobacco with a "priming" batch of PG (say 1oz tobacco and 30ml PG) in a heavy duty ziploc bag. You only want just enough that the tobacco will soak it all up so someone help if I got the ratio wrong. Squeeze the air out and throw it in the freezer overnight. Let it thaw out the next day, then freeze again. Thaw and freeze a third time. (This is to help with the flavor extraction).
2. Place tobacco onto square of cheese cloth and tie off. Place in Hermes Jar and add ~300% PG (example would be 90ml). Seal jar and store for about a month, gently swirling every few days.
3. Pour extract through metal mesh coffee filter into half pint Mason Jar and seal. Set jar aside for later.
4. Add ~10% PGA (3ml in example) and ~200% PG (60ml in example) to Hermes Jar with tobacco, seal jar and swirl gently to blend.
5. Place Hermes Jar in pressure cooker and simmer at ~180f for 8 hours, then turn off and open cooker. Let cool for 16 hours. Repeat the cycle, gently swirling the jar and topping off water between cycles.
6. Pour warm extract through mesh coffee filter into half pint Mason Jar with cold extract. Wrap cheese cloth in a coffee filter and gently squeeze over mesh filter to finish extract.
7. Pressure filter through a coffee filter (going to use an Aeropress for this step).
8. Hybid pressure/vacuum filter through a 5-micron absolute filter, then through a 2-micron absolute filter.
Has anyone here considered using aquarium air and water pumps? I have several aquariums and a bunch of experience with them, so they popped into my head right away. Quiet, fairly cheap, and designed to run on 110v without having to rig anything. There are also inline water blocks to keep from accidently sucking up any of your extract into your air pump that is generating your vacuum.
A hybrid filter would generate a vacuum under the filter and pressure above the filter. You can do this with a single pump if the intake is pulling air out from below the filter and the output is going in above the filter. Would generate a smooth flow with lower total pressure throughout.
So, what do all of the people who have been producing NETs think? Any tweaks, changes, or improvements recommended?
