To make a gallon of wine you will need a few supplies, most of which can be found in the average kitchen. You will need a large glass, plastic, or glazed ceramic bowl which holds one and a half gallons to put the wine in during its initial anaerobic phase. A loose fitting cover, which can be simply a clean dishtowel to cover this container. You will also need a stainless steel or plastic spoon to stir things with and a measuring cup.
You will need a clean gallon jug of some kind. A plastic milk jug, thoroughly cleaned, will work. Don't use bleach or other jugs which may have held some kind of cleaner. The plastic may not be approved for food products and it will prove almost impossible to get the odor out of the container, which would ruin the wine. If you use an old vinegar jug, make sure it has been cleaned thouroughly or you will have vinegar instead of wine. A small piece of plastic food wrap and a rubber band can be used to cover the opening while the wine is fermenting. Be sure to save the cap for use when the wine is finished fermenting.
A short piece of food quality plastic hose, like the type used for ice makers, is good to have to siphon the wine after it has finished fermenting. And of course and wine glass to drink the wine with when it is done. It is best to gather all the wine making supplies before you make it to make sure you have what you need when you need it.
