Single Malt Scotch, Blended Scotch, Irish whiskeys, Bourbon, Rye, American whiskeys, Japanese, Indian ... I like trying them all and keeping track of the ones I like, including a few Canadians. I haven't narrowed down to any particular style, but have favorites from all categories and price ranges.
I only indulge in the evenings and usually alone, rarely in excess (don't ask me to define "rarely").
I keep tasting notes and do comparisons. I enjoy it quite a bit.
