What Is a Shamrock Shake?
A Shamrock Shake is a sweet, mint-flavored green milkshake that is a product of McDonald’s® restaurants. The coloring of this dessert beverage is light Irish green, as Shamrock Shakes are meant to acknowledge Saint Patrick’s Day on March 17 of each year. Saint Patrick’s Day is an Irish Catholic feasting holiday that honors the patron saint of the same name. Saint Patrick’s Day is a national holiday in the Republic of Ireland and is celebrated by eating, drinking and wearing the color green. Green is the unofficial, customary color of Ireland and the shamrock, a species of clover with three leaves, is Ireland’s unofficial, customary symbol.
