You can do this several ways:
I prefer to do a few stripping runs (run the still hot and fast, don’t make cuts and collect everything down to 10-20%)
Save enough stripping runs to fill your still (I usually do 4 stripping runs to fill my 10 gallon still)
Once you have enough low wines (everything collected from the stripping runs) add them to the still and do a spirit run.
You can also just add your heads,tails to the next batch and re-run them that way. You will get a better product by doing stripping runs then a spirit run.
