sanitized glass marbles are commonly used to occupy headspace usingIs this a science project or something in the world of winemaking? Just curious as I have never heard of marbles outside the little glass ones our grandparents use to play with.
Kinda pointless to make my own wine if I am going to dump a gallon of shelf wine in there isnt it?I can't believe no one has offered this yet. Don't use marbles to "top up" your wine. Just top up with a similar wine off the shelf. I know it is done, and is considered acceptable practice, but you'll do better IMO to top up with a similar wine.
Ideally, you'd match the carboy size to the batch size. Marbles work for a very small amount of headspace, like 1/4" or something like that. They are kind of a pain, though- they roll around when you lift them up to the racking shelf, and they have a ton of sediment on them so you have to be careful not to stir them up.Kinda pointless to make my own wine if I am going to dump a gallon of shelf wine in there isnt it?
I mean, thats literally 20% of the total.
On my last batch I filled a 5 gallon carboy and then 2 bottles, thats just too much to top off in a 6.5 gallon carboy.
