Professional Grade All-Stainless Steel Boston Shaker Set with Strainer & Jigger
Designed by a career bartender for bartenders and serious cocktail enthusiasts. This cocktail shaker set is the exact style you will see behind craft cocktail bars worldwide, complete with a pro-quality Hawthorne Strainer and Japanese Jigger as well.
The Perfect Shaker Set for your Home Bar
Designed to be durable enough for a high-volume bar but perfect for any home bartender, this set is ideal for any bar.
- Boston Shaker provides an exceptional seal while still being easy to open and pour. It won't break like similar glass sets or freeze shut like Cobbler style shakers. It's perfectly balanced for comfort and speed behind the bar.
- High-end Hawthorne Strainer is custom designed for ergonomics, performance and beauty. Its high-density spring keeps pulp and ice fragments for your drink - while sitting comfortably in your hand.
- Durable Jigger measures your ingredients perfectly, and is comfortable enough for the longest bartending shift.
All components are made to work perfectly together, so you'll know for sure that the shaker tins are compatible and the hawthorne strainer will fit perfectly.
Why choose a Boston Shaker?
There are two common types of cocktail shakers: the Boston Shaker and the Cobbler Shaker. The Boston Shaker is made up of two cups, with one that nests inside the other. Cobbler shakers are a different shape with a "cap" on top. You'll find Boston Shakers like this one in most high-end cocktail bars, because they provide a better seal and don't freeze shut. You'll find they also provide a cleaner, dripless pour.
Start with the shaker, hawthorne strainer and jiggers that the pros use. You'll never have to upgrade - it's the perfect addition to your home (or high volume commercial) bar.
