Ok I got 8 new tobacco flavors in my crock pot and it does stay at 160 on warm.
After it goes through the 12 hour cycle.Let is cool down to room temp and put in the freezer for 3 days.I got my chest freezer to -15.Pull out and filter with a coffee filter.Then let the alcohol evaporate ( How long does it take to evaporate?) Then put back in to the freezer ( for how long?) Then take out and filter through a 1 micron filter.
Am I on the right path? Thanks for the help everyone
Also what is a good place to start when mixing 10%?
Here's a brief description of the process from start to finish;
Prepare a hot bath with water temperature set between 160F and 170F. Ethanol boils at 173F so try to keep the temperature below the boiling point.
Place shredded tobacco in a glass canning jar, pour in enough 190 proof PGA (
ethanol) to completely cover the tobacco then add about 25% more. Lightly seal the jar (
not too tight) and place it in the hot water bath, add enough warm water to the bath to match the level of ethanol inside the jar. Once the water temperature returns to 160F, process for 12 hours. Check periodically and add water to the bath as needed. After 12 hours have elapsed turn the heat off and let everything cool to room temperature. (NOTE:
For an even deeper flavor extraction, seal the jar tightly and let it sit at room temperature for a few weeks before proceeding to the next step.)
Put a coffee filter inside a funnel and place the funnel in a clean glass jar. Pour the ethanol (
now an extract) into the filter and wait for it to flow through before dumping the tobacco in. Once the tobacco has been dumped in and all loose solvent has filtered through carefully begin gathering/folding the edges of the coffee filter together to encapsulate the tobacco inside. In the palm of your hand, gently squeeze the encapsulated tobacco to release/recover as much extract as possible, slowly increase the squeezing pressure being careful not to rupture the filter. Discard the tobacco and filter. Seal the jar and place it in a freezer for 48 hours. Ethanol won't freeze, it just gets cold. While in the freezer some of the undesirable elements pulled from the tobacco during the extraction process will precipitate out of solution and coalesce in the bottom of the jar.
Put a coffee filter inside a funnel and place the funnel in a clean glass jar. Place this "filtering setup" in the freezer and allow it to get cold. Retrieve the extract from the freezer and carefully pour it into the coffee filter, if possible allow the filtering to take place inside the freezer so everything stays cold. Once the extract has filtered through, discard the coffee filter. Seal the extract and allow it to warm to room temperature. Remove the lid and allow 70% of the ethanol to evaporate off, this can take a day or longer depending on the amount of extract being reduced. (NOTE:
setting the open jar in front of a small fan will help speed evaporation.
Pouring the extract into a wide shallow container also helps.) Once reduced your extract can be filtered to whatever level you prefer, I recommend 3 micron filtration or better.
Mix the reduced extract at 7% to 12% strength. After mixing, allow time for the ethanol to evaporate from your mixed NET. Now you're ready to sample it, but remember that properly aging a mixed NET always improves its flavor. Enjoy!
