The home winemakers friend! Makes it easy to get the fruit off the pulp.
Also useful for straining hops for beermaking.
They are reusable. Red wine will stain them!
Most people use the coarse bag and it's the easiest for most homebrew.
For one gallon of wine or up to 200 g of hops
For straining 30 bottle batches of wine- You're might have to empty a few times though.
It takes ages for fruit pulp to filter through this, use the coarse one first unless you don't mind waiting!
If you squeeze the fruit too much through these bags you can get a lot of fine pulp settling out in the demi john.
