Arby's Jamocha Shake

Arby's Jamocha Shake is a popular coffee and chocolate flavored milkshake that has been a dessert staple for the fast food restaurant for decades.
Despite the use of coffee flavoring, a Jamocha actually has very little caffeine. This is because Arby's is using instant coffee powder and not concentrated brewed coffee in their Jamocha syrup.
Although the caffeine in Arby's Jamocha shake is low, the sugar and calorie content isn't.
Jamocha Shakes come in 3 sizes:
- Small (12 fl oz)
- Medium (16 fl oz)

The caffeine content will vary slightly by size.
