I've been using this Glencairn whisky glass for the past few years, and it's my favorite scotch glass. It won the winner of the 2006 Queen's Award for Innovation, and for good reason. The shape of the glass is meant to enhance the "color, body, aroma, taste and finish", according to the manufacturers.
The glass fits nicely in your hand with a full bowl that tapers to the rim. It's made from lead-free crystal, is dishwasher safe, and comes in a set of four.
