How many ounces of wine is in a proper glass?

A standard wine pour is 5 ounces. The perception of how generous 5 ounces of wine is, is relative to the glass you’re pouring it into. A typical serving size of 5 ounces of Pinot Noir in a 20-ounce Burgundy glass may appear a bit frugal. No matter the size of the glass, the top of the pour should be no higher than mid-bowl. This allows ample room for observation and swirling (agitation) without the concern of spilling.
