Arby’s Jamocha Shake: The Coffee Milkshake Fans Can’t Stop Ordering (2026 Guide)

I still remember the first time I ordered a Jamocha Shake at a drive-thru near my old office, expecting something close to a regular chocolate shake. It was not that at all—and honestly, it was better. If you have ever wondered what makes this coffee-flavored dessert so different from anything else on a fast food menu, you are in the right place.

In this guide, I am covering everything I have learned from actually ordering, tasting, and researching the Jamocha Shake over the years: what it tastes like, what it costs, the accurate nutrition and caffeine numbers, and how it stacks up against other options on the Arby’s menu.

What Is the Arby’s Jamocha Shake?

The Jamocha Shake is Arby’s signature coffee-flavored milkshake. The name itself is a blend of “java” and “mocha,” which gives you a hint of what you are getting before you even take a sip.

It is one of the few genuinely unique items on the Arby’s dessert menu. While most fast food chains stick strictly to vanilla, chocolate, or strawberry, Arby’s took a different route. By blending a classic vanilla shake base with their proprietary Jamocha (coffee and chocolate) syrup, this shake has become a permanent cult favorite among regulars.

What Does the Jamocha Shake Actually Taste Like?

This is the question I get asked most, so let me be direct: it is not a cold brew or iced coffee with ice cream tossed in. It is a thick, rich milkshake first, with a smooth roasted coffee flavor layered underneath a chocolatey sweetness.

Coffee, Chocolate, and a Hint of Malt

The flavor sits right in the sweet spot between a mocha latte and a classic chocolate malt. There is a noticeable coffee note on the finish that keeps it from tasting like straight chocolate syrup, which is exactly what separates it from a standard chocolate shake.

If you enjoy iced mochas or coffee-flavored desserts, you will likely love this. If you prefer purely sweet fruit or vanilla flavors, the slight coffee roast on the back end gives it a slightly more grown-up taste profile.

Arby’s Jamocha Shake Price: What You’ll Actually Pay

Pricing is one area where a lot of articles online give vague or outdated numbers. Generally, the Arby’s Jamocha Shake price falls between $3.29 and $5.49 depending on your size choice and local franchise pricing.

Prices vary by region and whether you order through the Arby’s app versus directly at the drive-thru. In my experience ordering across different regions, a small usually runs around $3.29–$3.79, a medium sits near $4.19–$4.69, and a large approaches $5.00+ during peak hours.

Checking current pricing on the official Arby’s app before heading out is always your safest bet, as regional franchise boards can shift slightly.

Jamocha Shake Nutrition, Calories, and Caffeine

If you are tracking your macros or watching calories, here is what you need to know about the numbers before pull up to the window.

Calories by Size

Based on Arby’s published nutrition data, here is the breakdown across standard sizes:

• Small Jamocha Shake (12–14 oz): ~540 to 590 calories
• Medium Jamocha Shake (16 oz): ~690 to 810 calories
• Large Jamocha Shake (24 oz): ~840 to 990+ calories

How Much Caffeine Is in a Jamocha Shake?

One of the biggest questions people have is whether drinking one late at night will keep them awake. Despite the rich coffee taste, the caffeine content in a Jamocha Shake is very low:

• Small: ~8.7 mg of caffeine
• Medium: ~11.6 mg of caffeine
• Large: ~16.0 mg of caffeine

For comparison, a standard 16 oz cup of regular brewed coffee contains around 150–200 mg of caffeine. A medium Jamocha Shake has about as much caffeine as a cup of decaf coffee or a small chocolate bar, meaning you can enjoy one as an evening treat without worrying about a late-night caffeine rush.

Jamocha Shake vs Other Arby’s Shakes

Arby’s occasionally rotates seasonal options like the summer Orange Cream Shake or winter Mint Chocolate Shake, but the Jamocha Shake has stayed a permanent menu fixture for decades. Because coffee and chocolate are year-round staples, it never feels out of season.

Compared to a standard vanilla or chocolate shake at Arby’s, the Jamocha offers significantly more depth. It is the option I recommend to anyone who finds traditional fast-food shakes a bit one-dimensional.

How to Order the Perfect Jamocha Shake at Arby’s

A few practical tips I’ve picked up over the years:

• Pair it with something salty: The richness of the coffee and chocolate balances exceptionally well with the saltiness of a Classic Roast Beef or Curly Fries.
• Check operating hours: Before heading out, double-check Arby’s hours, especially if you’re craving a late-night dessert.
• Timing matters: Shakes are typically not available during early morning hours. Check Arby’s breakfast hours and what time Arby’s serves lunch to make sure the full lunch menu—and shake machines—are active when you arrive.

Can You Make a Copycat Jamocha Shake at Home?

Yes, and it takes less than five minutes. The classic copycat formula uses four core ingredients:

• 3 cups vanilla ice cream
• 1/2 cup cold brewed coffee or strong espresso
• 1/4 cup whole milk
• 2 to 3 tbsp chocolate syrup

Blend everything together on high until smooth. If you want to recreate a full drive-thru experience at home, pair it with our popular copycat Arby’s roast beef recipe.
