In The Source this week, H. Bruce Miller explores the size of pint glasses at the "Big Four" breweries in town—literally taking a measuring cup in and pouring his beer into it to see exactly how much beer each place pours.

For some background, there are two commonly used types of "pint glasses": shaker glasses (the straight-walled glasses most people are familiar with) and imperial pint glasses (curving, bulbous-type at the top to hold more liquid). The problem is, shaker glasses typically hold only 14 ounces (a true pint is 16 ounces), and some "cheater" glasses only hold 12. Sometimes you can get a full 16 ounces if you fill right up to the rim and no foam or spillage is involved—not likely. The imperial pint glasses hold 20 ounces, but the same caveats apply—it has to be a full pour to get the exact 20.

(See The Honest Pint Project.)

Anyway, HBM determines the four breweries pour as such:

• Deschutes: imperial pints, but about 18 ounces: $4
• Bend Brewing: shaker glass, about 12 ounces: $4
• Cascade Lakes: imperial pints, about 18 ounces ("a bit over"): $4
• McMenamins: shaker glass, about 13 ounces: $4.15

It’s a good start, but I’m also curious about other places in town. The other two brewers, for example—Silver Moon and Wildfire (via JC’s). I know that Silver Moon serves up in shaker glasses (though I think they’re only $3), but I don’t know about JC’s/Wildfire.

And then there’s other places in town. The Blacksmith, for instance, serves their beer up in two types of glasses (neither of which are pints): a tall straight-walled glass (like a pilsner glass but maybe more like a stange), and a large snifter, all for $4 (on draft).

So who’s going to be doing the rest of the legwork on this? Let me know.
