This is a 16 oz aluminum bottle, sometimes called a "Cabottle" (CAn BOTTLE). They were first developed by CCL Container in Ontario, Canada. And like American Can Company in 1935 that went with a mid-sized brewery to introduce the first beer can in 1935, CCL found its first customer in a smaller brewery rather than with one of the huge mega-sized breweries like Anheuser-Busch. Big Sky Brewing in Montana was the first to use this package in the US for beer for its Moose Drool Beer (see left).

A few non-US breweries, Heineken, plus Sapporo and Kirin in Japan, used it before Big Sky. Big Sky was followed in the US by Pittsburgh Brewing using it for Iron City, coincidentally alsothe first brand and brewery to use the pull top can in 1962.

Anheuser-Busch began using it in 2005, and began issuing limited edition commemorative bottles for holidays and sporting events. Now Cabottles are a popular sub-specialty among beer can collectors. The ABC Chapter of the BCCA promotes collecting this type of can and has a nice photo database on their site. (Chapter links open a new window.)

Miller starting using a cabottle in 2008, but switched to a shorter version in 2009. They began issuing sports-themed cans and their baseball cans began coming out in 2010, often only sold in the stadium of the team in question. (Some are sold in outside stores in the team's home area). I haven't found the National's Miller Lite can anywhere but in the stadium.
