Depends if you are making extract or all grain. Not sure what equipment you have for wine-making but if you are making extract (with steeping grains), you will need a large stock pot (4 gallons), a fermenter, grain bag, hydrometer, airlock, capper, bottles and caps.
If you want to make All-grain beer you will need a pot large enough to boil 5.5-6 gallons of liquid and also a mash tun.
