I am trying my hand at making wine, starting out with 13 l of grape must. After primary fermentation, I separated the liquid from the pomace, ending up with some 8 l of liquid and approximately 5 l of pomace.
Can I compost the fermented pomace? Or will the alcohol and/or yeast cultures (which, at the end of primary fermentation, would be mostly, but not completely dead) harm the microflora in my pile?
I use a bottomless plastic compost bin. The wine was fermented with wild yeasts on the grapes – I did not use any additives, not even water, let alone sugar, cultivated yeasts, sulphites or anything else.
