Last week, Mom and I went to the Jack Daniel’s Distillery. It is the oldest registered distillery in the United States and is located in Lynchburg, Tennessee.
They use limestone spring water, corn, rye, and Barley to make the sour mash. The liquid is filtered through charcoal one drop at a time for mellowing. Then it is played in a wooden barrel for at least 4 years.
After 4 years, the barrel is opened and tested by professional tasters. They decide if the whiskey is ready or if it needs to spend a few more years in the barrel.
