These are by far my favorite espresso glasses. They are double walled to prevent the outside of the glass from getting hot. At about 2.7oz, they also hold the perfect shot of espresso. What I appreciate is the fact that this functionality is borne of such a beautiful yet simplistic design. The dual-walled thermo design is pure genius because it not only keeps you from picking up a hot glass, it also keeps the shot of espresso hotter longer.
My other espresso glasses are too big and always look half-full when I pour a single espresso shot into them, but the Culinary Couture ones are just right. They also have a well designed retail style packaging which makes these a great gift possibility for the coffee-lover on your list. I would definitely recommend these based on my own use.
