A Boston shaker seals best when the smaller tin sits inside the larger tin at a slight angle. Give the larger top tin a firm tap with the palm of your hand to create the seal; it doesn't take much force. If the tins are perfectly straight when you push them together, they may not lock properly. A slight angle is the secret.

This is one of the most common questions. As you shake, the cold causes the metal to contract slightly, creating a tight seal. Instead of pulling the tins apart, find the point where the rims meet, as indicated by a line of frost. Give the side of the larger tin a firm tap with the palm of your hand. The seal should pop open. If it's especially stubborn, running warm water over the outside of the larger tin for a few seconds usually does the trick, but you don't want to heat up your cocktail, so don't run the whole shaker under, and don't do this for too long.

Absolutely! Your Boston shaker is made from professional-grade stainless steel and is completely dishwasher-safe. If you want to keep it looking its best for years to come, hand washing and drying it promptly can help minimize water spots, but either method works great.

That's by design. Boston shakers are meant to be used with a Hawthorne strainer, which gives you much more control over your pour and does a better job filtering out ice and larger ingredients. It's one of the reasons professional bartenders prefer this style of shaker.

Both styles work beautifully and make excellent cocktails. A weighted/unweighted shaker pairs one weighted tin with one lighter tin, while a weighted/weighted shaker uses two weighted tins for a more balanced feel. Many people appreciate the extra heft and durability of two weighted tins, plus this combo tends to offer more flexibility for opening. Meanwhile, other bartenders prefer the lighter feel and more rigidity of a weighted/unweighted set. There isn't a “right” choice: it's all about which one feels better in your hands.

Absolutely! In fact, Boston shakers are a favorite for cocktails that use egg whites or aquafaba because they provide plenty of room to build a rich, silky foam. For best results, many bartenders use a dry shake (without ice) first before adding ice and shaking again.

Definitely! Boston shakers work just as well for mocktails, fresh juices, iced teas, lemonades, and other non-alcoholic drinks. Any time you want to chill ingredients quickly while adding a little dilution and aeration, a Boston shaker is the right tool for the job.

That's science doing its thing. As you shake, the ice rapidly chills the stainless steel. Moisture in the surrounding air condenses on the cold surface and freezes, creating that frosty exterior. It's a good sign that your cocktail is getting ice cold.
