Yes that is so true although some less educated in the fine art of whiskey making may think it does.
Even the location in the aging warehouse is important in the process.
My chum had an 18 year old Wiser's Canadian Rye whisky that he kept sealed for 30 years and when he opened it, there was a difference from the new version of their 18 year old expression, but it was because Wiser's had moved their distillery and the water they now use is not from the same source. They employ a different master blender, and there are other environmental issues. Combined they really did make a difference
