What is a nucleated Beer Can glass? It is a 16 ounce beer glass shaped like a beer can with a delicate pattern of pits in the bottom that form a point to break C02 out of solution. Without nucleation, a head cannot last for more than 3 or 4 minutes.
Our William’s Beer Can Glass features a nucleated hop cone pattern etched on its bottom, which keep a steady stream of bubbles rising to the surface from the center of the glass, preserving head. This glass has a tapered top, which helps concentrate hop aromas and protect the head. Made in the U.S.A.

Q: Will the nucleated can glass fit in a Yeti colster?
A: Good question, we have not tried this yet. The Nucleated Beer Cans are 3 and 7/8" in diameter.

Surprisingly.....FANTASTIC
I have always prefered to use tall, skinny glasses for my Pilsners and Lagers; I want all to see the color and the head, and very importantly, fill the nose before wetting the mouth. So I had my doubts about this glass, but am glad I tried it. I will now get a set -- or two! The beer can shape is excellent for viewing and quaffing, and much less likely to break than tall ones I use. And the nucleation spot works well, too.
Great glasses and excellent heads!
I bought four of these mostly for the look and shape. However, once I pour my first home brew in one, it kept a killer head and the bear paw at the bottom gave bubbles something to cling to to keep head nice and fresh. The cups are awesome, but do leave a little too much room for a 12oz beer. I drink all of my home brews out of my William's cups! Buy some, they are great! -Michael Sapp
Beer can glass
I bought a couple different glasses from Williams brewing for my home-brew area of my garage. Mostly for the name. 'Cause William is a good name. I love the beer can glass because its different from other glasses. And when friends come by, everybody has a different glass to drink from. Less confusion, better life. Brewdog333
Great Glass
The nucleated bottom helps raise a good head. The new style with slightly heavier glass feels firm in your hand. The colored decal shows off the Brewing Bear. You and your friends will enjoy this glass.
