What It Is
An iced oat latte is an iced latte — a cold version of the classic latte — made with oat milk instead of dairy milk. It’s built the same way — espresso over ice, then milk — with oat milk as the only change.
What Changes
Oat milk replaces dairy milk. The espresso and ice remain the same.
Oat milk has a mild, grain-forward flavor with a subtle cereal-like sweetness. It is thicker than most plant-based milks, which makes it well-suited for iced coffee drinks. The result is slightly sweeter with a smooth, less heavy texture than dairy milk. It doesn’t taste like dairy — it adds a subtle oat flavor to the drink.
How to Order

🔍 Key Details
Natural sweetness Oat milk contains natural sugars from the oats. Many people find an iced oat latte sweet enough without added syrup.
Barista oat milk Most cafés use barista-grade oat milk, which is formulated to mix smoothly with espresso without curdling or separating.
Oat milk vs. other plant milks Oat milk is creamier and less neutral than almond milk. It has a mild flavor that works well with coffee without competing with the espresso. See milk options.

📌 Good to Know
Separation in iced drinks
Oat milk can appear to separate or settle in an iced latte over time. This happens because oat milk contains fine grain particles that can sink to the bottom in a cold drink.
A quick stir recombines the texture and does not affect the flavor.
