During Prohibition years when alcohol sales were banned by the 18th amendment to the U.S. Constitution (1920-1933) wine growers would put large labels on their grape juice that stated:
"Warning: Will Ferment and turn into wine,"  and then proceeded to give detailed instructions of what NOT to do so the grape juice would not accidentally turn into wine!

The winemaking process takes from 4-6 weeks before your wine is ready to
bottle.  Don't forget to come in and start your holiday wine early enough
so you have time to bottle it before you get too busy!
