I'm all for the convenience of canned alcohol, so when I heard that Kahlúa is releasing a canned martini, my interest was piqued immediately. In honor of National Kahlúa Day, the popular coffee liqueur brand recently announced that it's releasing a new, ready-to-drink, espresso-style martini this Spring. The new drink, according to a product description, is a combination of Kahlúa, vodka, and coffee. Each can is 4.5 percent ABV and comes with a "smart nitrogen widget" that causes bubbles to form at the top of the drink in order to mimic the foam of an actual espresso once it's opened. The drinks will be available for customers to buy in four-packs this Spring.
