The all-metal shaker that keeps your drinks colder and has a better seal.
One evening a year or so ago, while at Death & Company in New York, I noticed that our bartender, Alex Day, was using an all-metal Boston-style shaker. In place of the mixing glass was a smaller metal tin, and when I asked him about it he swore by the design of it. Shortly thereafter I picked one up and have come to agree that this is my favorite shaker.
Firstly the all-metal system is a much better conductor so the cold of the ice infuses the shaker far more quickly whereas glass holds its heat a little longer and melts the ice while in the shaker. The fact that the metal holds less heat also means that the air in the shaker gets colder much faster creating a vacuum more quickly inside of the shaker. Secondly, the shape of the smaller tin of the shaker is very important. It has a beveled edge, which has a far greater surface area than the small amount of glass that makes contact in a normal shaker, creating a much better seal.
This seal is super important when you are making cocktails with egg white, which for some reason has a tendency to find its way out of standard mixing glass shakers while shaking vigorously. The walls and lamps around my bar can attest to this leakiness.
Perhaps the best news of all, my recession addled readers, is that this shaker is seriously cheap. It comes from the cheesy-as-can-be flair bartending supply store called barsupplies.com. If you can wade through the shooters, beer towers, and “bartending” DVDs, there are actually some great products here.
Do yourself a favor and splurge on this thing.
