*A Must-Have Glass
The old-fashioned glass is a short tumbler that is also often called either a lowball or a rocks glass. They hold between 6 and 8 ounces and are also available as a double old-fashioned (left of the photo), holding up to 10 or 12 ounces.
These glasses are typically used for short mixed drinks that are often served with ice, though not always. Popular lowballs like the White Russian, Rusty Nail, and Old-fashioned are often served in these glasses.
The smaller old-fashioned glasses can be used for serving a straight or neat pour of liquor, typically a dark spirit like whiskey. The doubled old-fashioned glasses are also ideal for serving either a mixed drink or shot of liquor with single large ice cubes or ice balls.
