Milk Steaming Temperature Calculator

Steam cow’s milk to about 140 °F (60 °C); plant milks like it a little cooler. Pick your drink and milk to see when to stop the wand, how much cold milk to pour, how much to stretch it and which pitcher to use.

How to Steam Milk

  1. Pour cold milk into the pitcher, up to just below the base of the spout.
  2. Purge the steam wand, then put the tip just under the surface, a little off-center.
  3. Open the steam fully. Add air with a quiet paper-tearing sound until the milk has grown by the stretch above and the pitcher feels lukewarm (about 100 °F / 38 °C).
  4. Raise the pitcher so the tip sinks slightly and the milk spins in a whirlpool. Stop adding air.
  5. Turn the steam off a few degrees before the target, then wipe and purge the wand.
  6. Tap the pitcher on the counter and swirl until the milk is glossy, then pour right away.

Frequently Asked Questions

What temperature should you steam milk to?
For cow’s milk, aim for about 140 °F (60 °C), within a range of 130–150 °F (55–65 °C). That is where milk tastes sweetest. Above about 160 °F (71 °C) it starts to taste flat or cooked, and the foam breaks down faster.
What temperature should you steam oat milk to?
Barista oat milk is best around 130–140 °F (55–60 °C). It foams well, but past about 150 °F (65 °C) it can turn thick or gummy. Almond milk is more sensitive still: keep it near 125–135 °F (52–57 °C).
How do I know when milk is hot enough without a thermometer?
Hold the side of the pitcher. When it gets too hot to keep your hand on for more than a second or two, the milk is around 140 °F (60 °C). A clip-on thermometer is more reliable while you learn. Turn the steam off about 5 °F (3 °C) early, because the temperature keeps rising for a moment.
How much milk do I need for a latte?
For a 240 ml (8 oz) latte with one shot, pour about 190 ml (6.4 fl oz) of cold milk. That includes about 10% extra so you don’t run out while pouring. Steaming stretches it by about 20%.
What size milk pitcher should I use?
A 12 oz (350 ml) pitcher suits one cappuccino, flat white or small latte. A 20 oz (600 ml) pitcher suits one large latte or two smaller drinks. Fill it to just below the base of the spout, roughly a third full, so there is room for the milk to expand and spin.
Why does my steamed milk have big bubbles?
The wand tip is too far above the surface, or you added air for too long. Introduce air only at the start, with the tip just under the surface and a quiet paper-tearing sound. Once the pitcher feels lukewarm, sink the tip slightly to spin the milk and fold the bubbles in. Tap and swirl the pitcher before pouring.
Which coffee is best for milk drinks?
Medium to dark roasts with chocolate, caramel or nutty notes hold up best under milk. Browse 167 espresso-friendly coffees in our catalog.
