I signed up for on-line wine making classes last week. I just completed my first lesson and test. I got a 100% yippee!
Major take aways...
1) Yeast + must + sugar - oxygen = ethanol/alcohol (C2H5OH) + carbon dioxide gas (CO2)
2) Yeast + must + sugar + oxygen = water (H20) + sulfur dioxide gas (SO2)
3) Yeast needs a small amount of oxygen initially to multiply (ramp up). Once it consumes a certain amount of oxygen present in the must, then it will begin to produce ethanol and carbon dioxide gas.
4) All wine contains some level of sulfur dioxide. The acceptable level of ethanol & sulfur dioxide in commercial wine is regulated by big brother.
5) legal limits on how much wine you can make without a license. In most parts of the United States this limit is 100 gallons per person per year or 200 gallons for a married couple per year. Producing more than this will requires a license from big brother.
