Milk Steaming: the full procedure
Steam milk to consistent microfoam and temperature, and keep the wand clean after every pour.
- Applies to: Baristas.
- Frequency: Every milk drink.
- Scope: Covers milk steaming. Burn/steam safety follows the equipment manual + safety plan.
What you need
- Steam pitcher
- Thermometer (or by feel to standard)
The procedure, step by step
- Fill and purge — Fill the pitcher to about a third–half with cold milk, and purge the steam wand before inserting.
- Stretch (add air) — Position the tip just below the surface to introduce air for a few seconds (more for foamier drinks, less for flat whites).
- Texture (whirlpool) — Submerge the tip to create a whirlpool that folds the foam into smooth, glossy microfoam — no big bubbles.
- Stop at temperature — Stop at your target temperature (commonly ~60–68°C / 140–155°F — do not scald). Tap and swirl to integrate.
- Pour, then clean the wand — Pour within ~30–60 s for best texture, then immediately purge and wipe the steam wand — milk bakes on fast (hygiene + quality).
Quality check before you finish
- Cold milk; pitcher ~1/3–1/2; wand purged.
- Air stretched to drink type.
- Textured to glossy microfoam, no big bubbles.
- Stopped at target temp; tapped/swirled.
- Poured promptly; wand purged + wiped after.
This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Coffee Shop business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan. Open the tool above to print it, toggle ink-saver, or (with a free ToolFluency Business account) edit it to match your own workflow.

Frequently asked questions
How do you steam milk for lattes?
Purge the wand, position it just below the surface to introduce air (stretch), then submerge to create a whirlpool that texturizes into microfoam, stopping at the target temperature (do not scald). Wipe and purge the wand immediately after. The SOP sets your texture and temp standard.
Why clean the steam wand after every drink?
Milk bakes onto a hot wand fast, harboring bacteria and ruining the next pour. Purging and wiping after every steam is both a hygiene and a quality step — the SOP makes it non-skippable.
