Could be funnier if they got the facts right ...
"Once fermented into a clear alcohol spirit,
whisky blends are added to give colour, taste and viscosity, and the product is bottled with the name and age of the contributor"
Once whatever you use is fermented the alcohol is boiled off by a process of distillation to make the whiskey/spirit. Once the alcohol is removed the mash could have contained yak's pee. I think a diabetics sugar would not produce much spirit. When I used to make wine I used 3lb of sugar to a gallon to get just 11 or 12% by weight.
