Mixing seltzer with a splash of vinegar makes a simple, flavorful, no-sugar mocktail.Using apple-cider vinegar may help support healthy blood sugar, cholesterol and digestion.Easy evening drinks like this one can feel special—no alcohol needed. Evenings are easily my favorite time of the day. I love taking the time to make dinner and take a breather from my to-dos before going to bed. As part of that wind-down routine, I also enjoy sipping a fun nightly drink—but lately that drink doesn’t include alcohol. Now in my 30s, I’ve started drinking less, especially during the week. During the day, I mostly stick to water (and an occasional coffee), but in the evening I crave something that feels more special and helps me relax. Enter: my go-to two-ingredient mocktail made with seltzer and a splash of vinegar. It’s refreshing, easy to prepare and even offers some health benefits. Here’s how I make it—and why it’s so good. How to Make a Seltzer + Vinegar Mocktail Making this mocktail couldn’t be easier. I pour one 12-ounce can of flavored seltzer (I like to switch up the flavor each week, and my favorite brand is Spindrift) over ice and stir in about ½ ounce of vinegar. I usually use apple-cider vinegar, but I also like experimenting with other types I might have on hand, like sherry vinegar or flavored ones. For example, a friend gifted me a bottle of watermelon-mint-flavored white balsamic vinegar, which was fantastic paired with lime seltzer. To make it feel a little extra special, I’ll garnish with a slice of citrus or sprig of mint if I have it on hand. Don't Miss Eat Too Much Sugar Last Night? Here's What Dietitians Recommend You Do Today What's Really in Packaged Egg Whites? Why I Love This Mocktail There are few reasons this drink has become a nightly staple. It’s Full of Flavor It reminds me of a cocktail called a shrub, which uses a vinegar syrup for a sweet-tart effect. My version is even easier—and doesn’t contain any added sugar. Between the tanginess from the vinegar and the subtle fruit flavor of the seltzer, it’s perfectly satisfying without being overly sweet. It May Support Your Health Apple-cider vinegar has been linked to several potential health benefits. Some research suggests daily intake of cider vinegar may lower fasting blood sugar levels and LDL (known as “bad”) cholesterol. If you’re using a raw, unfiltered variety that includes the “mother” in the bottle, you’ll also get probiotics that can support healthy digestion and a healthy gut microbiome. Plus, cider vinegar has antimicrobial and antifungal properties, which may help support your immune system—something I appreciate during cold and flu season. It’s a Simple, Feel-Good Ritual Small changes can make a big difference in your routine. Swapping a glass of wine or cocktail for a seltzer-vinegar mocktail a few nights a week is one way I support my health without overhauling my lifestyle. It is important to note that if you experience acid reflux, vinegar-based drinks may trigger symptoms. Always talk to a health care provider before adding something new to your routine.
