If you wish to see the production (distillery) of whiskey you will not see any. The tour is very basic ($10) and give bit of info about the distillery and about whiskey. Testing cost $2 - $4 depending on what size and what you would like to try. However if you take the tour, you get to try 63 precast whiskey (include in the cost of the tour) and you can also buy it during the tour. This is not available at the gift shop.
