Glengoyne distillery

The last day in Scotland. We have decided to visit a Scotch whiskey distillery which has been missed so far. Checking a tourist site, there are two distilleries near Glasgow and I have chosen one of them, Glengoyne, because people appreciate this distillery saying it is located in quite beautiful place. We have joined a tour with a shot served per each when beginning. My wife does not drink strong alcohol, which means naturally mine are two shots.
