and you can always go to your local supermarket, buy a gallon of fruit juice (not soda, but real fruit juice) such as pomegranate, or mango or apricot (sold in the chiller section), pour into your sanitized bucket, add pectic enzyme, wait 12 hours then pitch (add) wine yeast (71B, K1V , QA23, 47D, or EC-1118) and allow the juice to ferment until the gravity drops to about 1.005 (means you should buy an hydrometer) and then siphon into a gallon carboy, seal with a drilled bung and airlock (the airlock filled with water) and allow the wine to age a couple of months, rack again and allow to age another two or three months and then package (bottle) and drink. You could add 1 lb or more sugar to the juice before you add the yeast, mix thoroughly and then pitch (add) the yeast. That will increase the ABV (alcohol by volume) of your wine by about 5.25% - in other words, will produce a wine with about 9% ABV. If you added 1.5 lbs of sugar to the juice (no heat), you will produce a wine at about 11% ABV which is pretty standard.
You could buy frozen berries (strawberries, raspberries, blackberries, cherries etc) allow them to thaw, add pectic enzyme, wait 12 hours or more, add yeast and make wine from fruit (rather than fruit juice). Takes about 10 lbs of fruit to produce 1 gallon of wine. Adding water dilutes the juice. You don't want to add water.
