Single Malt Scotch - Preferably Lagavulin - in an appropriate glass (see note below) with 3 cubes of ice max. (Ice Cubes should be made with distilled water) - Perfect! Everyday Lower Cost Substitute Scotch could include: Laphroaig, Talisker, Caol Ila or in a jam The Glenlivet will work.
Glass: Wife gave me a pair of these for Christmas many years ago:RIEDEL Engraved Whiskey/Scotch Glass Sets

I do like to sip some ice water along the way with a long lasting cigar.
