White dog is the spirit that comes off the still and when placed in a oak barrel, becomes whiskey. Moonshine is rarely ever 100% grain and most often is 100% fermented sugar, making it more like rum than whiskey. White dog is always safe to drink. Moonshine can be lethal to drink. My rule is never drink moonshine from an unknown source, unless you like blindness, lead poisoning or death.
"Our people live almost exclusively on whiskey" - E H Taylor, Jr. 25 April 1873
