McDonald's cup featuring Uncle O'Grimacey.
The Shamrock Shake was first introduced in 1970. Rogers Merchandising in Chicago created the shake. Initially, the shake was lemon/lime flavored with Vanilla Ice Cream, Lemon Lime Sherbert, and Vanilla Syrup. By 1973, the shake was merely a green colored vanilla shake, eliminating the Lemon Lime Sherbert. Then in 1983, the shake added mint flavoring and today its still a mint shake, consisting of Mint Ice Cream base, Vanilla Syrup, and Milk. James Byrne, the executive artist at the firm, used a family recipe for the shake. Shamrock Shakes are sold at all American and select Canadian stores during the months of February and March, as well as in Ireland.
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.
