The Perlini Carbonating Cocktail System was originally designed by professional bartenders for heavy-duty restaurant and bar use. Now that same product is available for home use, with handy, recyclable CO2 cartridges. Kit contains one Perlini Carbonating Cocktail Shaker; one Perlini Hand-Held Pressurizer; six beverage-grade 16g CO2 cartridges; spare valve and gasket; instructions. The Perlini Cocktail Shaker in this kit is exactly the same as in the Perlini restaurant version. Made of nearly indestructable BPA-free Tritan, it is easy to clean and features a built-in strainer to hold back the ice while pouring. Simply add ice to the shaker along with all of the ingredients (liquors, mixers, fruit, etc.), close the shaker, pressurize, shake for a few seconds, and you’re done! Add sparkle to anything–everything’s better with bubbles! The perfect holiday gift for cocktail enthusiasts. Fun for weddings, birthdays, housewarmings, Thanksgiving, Christmas, New Year’s, Valentine’s, Father’s Day, and more!
