Apfelwein. Its corn sugar, or dextrose. 2 lbs plus 5 gallons of apple juice with montrachet wine yeast for 6 weeks at room temp = delicious.
An alcohol boost to a regular brew.
Making wheaties into frosted flakes.
I wouldnt use it for starters as supposedly it gets the yeast used to simple sugars and does not give them the nutrition like a weak wort will for cell health.
