The Arby’s Jamocha Shake has been a menu favorite for decades, loved for its creamy texture and the irresistible combination of coffee and chocolate flavors.
The Jamocha Shake is Arby’s signature coffee‑flavored milkshake, blending vanilla shake mix with a special “Jamocha” syrup made from cocoa and instant coffee. It’s topped with whipped cream and often finished with a drizzle of chocolate sauce.
Caffeine Content in Arby’s Jamocha Shake
Despite its coffee taste, the Jamocha Shake contains very little caffeine compared to brewed coffee or espresso drinks. The caffeine comes from the instant coffee in the Jamocha syrup, not from brewed coffee.
Caffeine by Size:
- Small (12 fl oz) – 8.7 mg caffeine
- Medium (16 fl oz) – 11.6 mg caffeine
- Large (22 fl oz) – 16 mg caffeine
For comparison, a typical 8 fl oz cup of brewed coffee has around 95 mg of caffeine — nearly nine times more than a medium Jamocha Shake. This makes the shake a low‑caffeine option, suitable for those who want the flavor of coffee without a strong stimulant effect.
Sugar & Calorie Content
Where the Jamocha Shake really stands out is in its sugar and calorie load. The combination of shake mix, syrup, and toppings makes it a high‑energy treat.
Nutrition by Size:
- Small (12 fl oz) – 440 kcal, 61 g sugar
- Medium (16 fl oz) – 830 kcal, 116 g sugar
- Large (22 fl oz) – 1,030 kcal, 150 g sugar
To put that in perspective, the medium size contains more than double the daily added sugar limit recommended for most adults.
Ingredients Overview
The Jamocha Shake’s signature taste comes from a carefully balanced mix of creamy dairy, sweeteners, and flavoring agents that create its rich coffee‑chocolate profile.
- Vanilla Shake Mix – whole milk, cream, sugar, and stabilizers for creaminess.
- Jamocha Syrup – corn syrup, cocoa processed with alkali, instant coffee, caramel color, and flavorings.
- Toppings – whipped cream and chocolate drizzle for extra sweetness and presentation.
Together, these components deliver the thick, indulgent texture and sweet mocha flavor that make the Jamocha Shake one of Arby’s most popular dessert beverages.
