how i do it is put 1 bottle of home made wine in a large pot that has a lid.
put a glass in the center of pot with a few buds in it. turn on the stove, when the wine starts to boil (which is quick cuz its alcohol) cover the pot with its lid but put the lid on upside down and pour ice in the lid to cool the alcohol on the dome.
the alcohol will collect in the center of the domethen drip into the glass it will allready be hot and will drip onto the bud extracting the THC. When about 15 minutes wirth of boing is up you can turn off the stove and remove the glass(caution glass will be hot) take out the buds and enjoy your new drink.
I can post MY home made wine recipie if wanted. will make 3 gallons in 3 weeks.
