This is one of the most essential bits of kit behind any bar. A 16oz Boston glass is the glass half of a Boston shaker, pairing with a metal tin to mix cocktails quickly and properly. It’s got that classic slightly tapered shape and is made from thick, durable glass so it can handle being shaken, stirred, or even used for muddling ingredients. The size (around 450ml) is standard, so it fits perfectly with a 28oz shaker tin to create a tight seal.
One of the nice things about using glass instead of a second metal tin is that you can actually see what’s happening inside while you mix - helpful when you’re learning or just want to get things spot on. It’s not just for shaking either - a lot of people use it as a mixing glass for stirred drinks or even as a serving glass in more casual setups.
