I'm a HUGE single malt fan.
Currently have a bottle of Ardbeg 10, Laphraoig Quarter Cask, and Talisker Distiller's Edition 1996...all exquisite.
My absolute favorite is Talisker 18, followed by Ardbeg 10, Lagavulin 16, and the Laphraoig QC (which I just bought this weekend and is absolutely divine).
I'm a big fan of the peat monsters, obviously.
To me, Glenlivet is garbage.
