Caffe Misto at Starbucks — The Complete Guide

It sits quietly on the Starbucks menu — no frills, no seasonal hype, no elaborate syrup name. Just coffee and steamed milk in equal proportion. The Caffe Misto is one of the most underrated drinks at Starbucks, and once you understand what it actually is, it becomes hard to order anything else on mornings when you want something warm, smooth, and satisfying without the intensity of an espresso drink. But there is one thing you can do at home that Starbucks cannot: make it with genuinely low acid coffee.

What Is a Caffe Misto?A Caffe Misto is equal parts brewed drip coffee and steamed milk — the American version of a cafe au lait. Made with Pike Place Roast by default at Starbucks, it is smooth, lighter in body than espresso drinks, lower in calories, and endlessly customizable.

Caffe Misto vs. Latte — The Complete Difference

The most common confusion is between a Caffe Misto and a latte. They look similar in the cup. They feel similar in texture. But there is a fundamental difference in how they are made — and that difference affects everything from flavor to caffeine to calories to price:

Factor Caffe Misto Latte
Coffee Base Drip brewed coffee Espresso
Caffeine (grande) ~150mg ~150mg (2 shots)
Flavor Profile Lighter, roasty, smooth Bold, rich, creamy
Milk Ratio 50% coffee / 50% milk ~75% milk / 25% espresso
Calories (grande, 2% milk) ~110 ~190
Price ~$3.50–$4.25 ~$5.25–$6.50
Foam Light foam layer Minimal foam (flat white style)

The Acid Problem With the Starbucks Caffe Misto

The Caffe Misto is made with Starbucks Pike Place Roast — a medium roast that sits at approximately pH 4.7–5.0. This is the standard acidity level for mainstream coffee. For the approximately 60 million Americans who experience regular acid reflux or heartburn, this acidity level can trigger symptoms even in a milk-diluted format. Milk buffers some of the acid, but the underlying pH of the coffee base remains unchanged.

⚠ The Starbucks Misto Acid Reality
Starbucks Pike Place Roast (the Caffe Misto base) sits at pH 4.7–5.0. Even diluted 50/50 with milk, the residual acidity can aggravate acid reflux and heartburn in sensitive drinkers. The home Misto upgrade: use Puroast Half Caff at pH 5.82 as your coffee base for the same smooth milk-and-coffee experience with 5X less acid.

How to Order a Caffe Misto at Starbucks

Ordering a Caffe Misto is simple — but knowing the full customization menu unlocks significant options:

  • Standard order: Simply say "Caffe Misto" and your size (tall, grande, venti)
  • Half caff Misto: Ask for half caff brewed coffee — Starbucks will blend decaf and regular Pike Place
  • Milk alternatives: Oat, almond, coconut, soy — all work in a Misto
  • Extra hot: Request extra hot steamed milk for a warmer cup
  • Light foam: Caffe Misto comes with a light foam layer by default — ask for no foam if preferred
  • Flavor syrup: Vanilla, caramel, or hazelnut syrup pair naturally with the roasty coffee base
  • Ristretto base: Not available for Misto (drip-based), but you can ask for an Americano Misto as a workaround

Caffe Misto Calories — By Size and Milk Type

One of the greatest advantages of the Caffe Misto is its calorie efficiency compared to espresso-based drinks. Here is the full calorie breakdown:

Size Whole Milk 2% Milk Oat Milk Almond Milk
Tall (12oz) ~100 ~80 ~100 ~60
Grande (16oz) ~140 ~110 ~130 ~75
Venti (20oz) ~180 ~140 ~165 ~100

How to Make a Caffe Misto at Home — 3 Methods

Method 1: Standard Drip + Frother

Brew your coffee at standard strength in a drip maker. Heat your milk in the microwave or on the stovetop to approximately 150°F. Use a handheld milk frother to create light foam. Combine 1:1 in your mug. Result: ~$0.25 per cup versus $4.00 at Starbucks.

Method 2: French Press + Steam Wand (If You Have One)

Brew a full-strength French press and steam milk with your espresso machine's steam wand. The French press gives a richer, more textured body that pairs beautifully with steamed whole milk or oat milk. Especially good with Puroast Half Caff French Roast.

Method 3: Cold Misto (Iced Cafe Au Lait)

Brew double-strength coffee (double grounds, same water volume) and pour over ice. Add cold milk 1:1. Shake or stir. Optionally add a shot of flavored syrup. Cold Misto is refreshing, low-calorie, and easier on the stomach when made with low acid coffee.
