Blue Marble Cocktails arrive in cans which look like small juice cans. I’m normally leery of canned cocktails. But during this COVID-19 era, these small-sized drinks are handy additions to social-distanced events like driveway happy hours. Served chilled with a straw or over ice in a small glass, the seven-ounce cocktails are only 15 percent ABV. The good news is that of the three versions tried—Marble-rita, Bloody Mary, and the crowd favorite, Moscow Mule, are relatively true to type and not too sweet and sour.
