About Our Drinks

Sip Happens – We Brew Boldly.
At Boom N’ Brew, we’re not just pouring drinks—we’re crafting moments. From rich, smooth double espressos and silky flat whites to bold dirty chai lattes and layered iced matcha creations, our espresso bar offers something for every kind of coffee lover.

Our drinks are thoughtfully built, starting with precise ratios and quality ingredients. Whether you’re sipping on a classic latte, a strong Americano, or exploring our unique mushroom brews, you’ll taste the difference in every cup. We use ceremonial-grade cocoa, coconut sugar, and offer a full range of milk options, from whole to oat, almond, soy, and more.

Need it cold? Try our signature cold brew, fruity summer refreshers, or indulgent iced espresso drinks. Want something stronger? We also serve cocktails like espresso martinis and Irish coffee—with a Boom twist.

Every drink is made with intention, whether you’re relaxing on a red velvet couch or grabbing something hot and fast to-go. We're your neighborhood spot in the heart of downtown St. Louis—bringing bold brews, secret treats, and a touch of magic to Washington Avenue.
