OK, who would buy these? I might buy a Pina Colada or Margarita pop, but a beer one?? GAK! McLEAN, Va. - It might be one of the great alcoholic innovations of the 21st century - the frozen beer pop, served by an Alexandria restaurateur and bar owner in a variety of sizes and flavors like "Raspbeer-y" and "fudgesicle." The story of the frozen beer pop began last week at Rustico Restaurant, where executive chef Frank Morales began selling the frozen treats to customers looking for a more adult way to beat the heat. After weeks of testing several hundred beer varieties to find flavors that taste good on a stick, Rustico finally settled on three flavors: "Raspbeer-y," made with a Belgian, fruit-style beer; "Plum," made from a Belgian Lambic brew; and the "Fudgesicle," made with a stout with bittersweet chocolate undertones. He plans to offer other flavors on a rotating basis. The beer pops sell for $4 in the six-ounce size, shaped like a traditional Popsicle, and $6 for a larger "beer cone."
