I really love drinking whisky. I enjoy the Irish blends more myself. Jameson and Tullamore dew are my favorites. 
I wonder what grains are in the ones you drink.  Various grains are used for different varieties like barley, corn, rye, and wheat.
I would assume wheat is definitely one of the ingredients but that's a very good question. I think Irish blends are different from the American ones.
I find it very interesting that whisky is a strictly regulated spirit worldwide and it does have a lot of classes and types as well.
It's just one of those drinks that just works perfectly. I love it with just ice or even with a coca cola. Some people like it with Sprite.
