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.
The characteristics of the different classes and types are the fermentation of the grains, distillation and aging in wooden barrels.  It seems most people definitely have their favorites.  The only time I've had it is for a cough I couldn't get rid of.
I guess it would be good if you had a nasty cough, it burns though! I love aged whisky the taste and aroma definitely change the longer it ages for.
There is even a lot of debate between how it's spelled - either whiskEy or whisky.
