New Amsterdam 100pf Vodka 375

New Amsterdam 100pf is a 375 ml flask of American vodka from Massachusetts. The "pf" means proof, so the label points to a bottling at 100 proof, or 50% alcohol by volume. That is noticeably stronger than the 80-proof standard for the category. The details we have don't list a base ingredient or any tasting notes. At this strength, expect a clean, neutral spirit with a firmer alcohol presence and more weight on the palate than a standard-strength bottling. Nothing here suggests flavoring, so treat it as a plain, unflavored vodka. The extra strength matters most in mixed drinks. A cocktail built on a 100-proof vodka keeps its spirit character when ice melts, and it tastes less diluted. This helps in a Moscow Mule, where ginger beer and lime can flatten a weaker pour. It also helps in a Bloody Mary, where tomato juice, horseradish and hot sauce are heavy and tend to bury a gentler base. A Cosmopolitan is another good fit, since the vodka has to hold up against cranberry and lime. The same goes for an Espresso Martini, where cold coffee and coffee liqueur can drown out a lighter spirit. Because the proof is higher, pour a little less than the recipe calls for if you want a drink closer to usual strength. The other option is to stir or shake a bit longer for more dilution. For a classic Martini, the higher proof gives a drier, more assertive result. Stir it with plenty of ice, then strain it into a chilled coupe or martini glass. Add an olive or a lemon twist, depending on whether you want a savory or a brighter drink. You can also drink it neat, but keep the strength in mind. Store the bottle in the freezer, where the high alcohol content keeps it from freezing. Pour it very cold into a small glass, or over a large ice cube in a rocks glass, so the cold softens the alcohol heat. Its 375 ml size suits a small gathering, a home bar that wants a strong vodka for mixing, or a bag where a full-size bottle would be awkward.
