That can't be possible, glucose is required for fermentation to make the ethanol or it couldn't be alcoholic. It's the only reason college students could keep on weight where I was from.
I wonder if it is all some marketing scheme where they are saying zero sugar because there is "no added sugar". Basically making the non flavored malt alcohol, then flavoring it and adding artificial sweetener to get the sweetness.
Otherwise if we could ferment and make alcohol without sugars, many people would start drinking 0 calories alcoholic beverages, as drinking 10 beers gives you about 1200 calories (bud light, miller light whatever shitty beers are around 120 calories a piece). Alcoholics would save 2lbs of weight gain a week there.
That annoyed me to no end. I have to wonder about the big push in artificial sweeteners recently; are they cheaper than corn syrup now? Are there enough people who are trying to cut back on sugar but also actually like the taste of dissolved copper in their drinks to keep soda profits high?
