Added supplies to make wine? Hard to say since we have no idea what you have.
Depends on what you want to brew. Different wines take different ingredients/additives. Find a recipe you would like to try and get the stuff for it. A bucket and a couple 5g carboy's are helpful for 5g batches. 1g carboy would work for a 1g batch of juice wine, etc.
I have two five gal buckets one five gal Carboy two six gal carboy's. Bottling bucket, and borrowing wand, auto siphon. I'm looking to make wine from a kit at first.
If you make beer you can make wine. Same process just different ingredients. If you're using a kit then you don't even have to worry about that part of it. You'll need wine bottles of course and if you don't have a shop filter and bottle it, then you'll need a filter (if you want to filter it) and a corker (u can get one for $15), but you won't need that for a couple months so get it started and worry about that later... And alot of patience.
