The Shamrock Shake is a seasonal green-dyed mint flavored milkshake dessert sold at McDonald's to celebrate St. Patrick's Day.
Origin
The Shamrock Shake was first introduced in 1970.[1] Rogers Merchandising in Chicago created the shake. Initially, the shake was lemon/lime flavored with vanilla ice cream, lemon/lime sherbet, and vanilla syrup. By 1973, the shake was merely a green colored vanilla shake, eliminating the lemon/lime sherbet. It is now mint flavored.
Shamrock Shakes are sold at all American[2] and select Canadian stores during the months of February and March,[1] as well as in Ireland.[3]
Advertising
During the 1980s, McDonald’s used the Uncle O'Grimacey character to market Shamrock Shakes, but has since phased it out.
In 1980, McDonald's introduced the Shamrock Sundae which consisted of vanilla ice cream topped with a mint green Shamrock syrup. The product was discontinued after one year due to poor sales.[2]
