Plant milk

Almond milk

Also sold as: almond drink

Thin and low in protein, so foam is largely whatever the formulation provides — and it separates against espresso readily.

Type
Plant
Texture when steamed
Thin and watery in the mouth compared with dairy or oat, with a dry finish.
Temperature
Little tolerance for being held hot; make it and serve it.

In short

Almond drink is mostly water with a small proportion of ground almonds, usually with added vitamins, a little oil and stabilisers. It has far less protein than dairy or soy, and protein is what milk foam is built from.

That one fact explains its behaviour in coffee: thin foam that does not last, and a tendency to separate into flecks when it meets hot espresso. Both can be managed. Neither can be made to disappear entirely.

Standard and barista cartons are different products

Sourced

Food-science reviews of plant drinks for coffee use describe them as far more variable than cow's milk in the kind and state of their proteins, and note that the oils and insoluble particles they contain can weaken foam. Almond drink sits at the difficult end of that range because there is so little protein to begin with.

Versions sold as barista or for coffee are reformulated to cope. Typical additions are a little more fat, a gum or other stabiliser to hold the foam and keep particles suspended, and an acidity regulator to buffer the drink against the acidity of coffee. The ingredients list is the place to check. A carton with none of those will foam and blend much less well, and that is the product, not your technique.

Why it separates in coffee

CoffeeHQ explanation

Coffee is mildly acidic and hot. Plant proteins stay suspended only within a certain range of acidity; pushed past it, they clump together and the drink looks curdled. Heat makes this happen faster. Published work on soy drink in coffee found that whether it separates depends on temperature, on acidity and on the proportions of coffee and drink, and the same factors are at work with almond.

This is why the order and temperature of mixing matter so much, and why a light, acidic coffee splits a plant drink more readily than a dark, low-acid one. Separation caused by hot, acidic coffee is a fault of appearance and texture, and does not mean the drink has gone off. A carton that smells sour, or that has separated before it meets the coffee, is a different matter and should not be used.

Steaming and combining it

CoffeeHQ explanation

  1. Shake the carton well. Solids settle. An unshaken carton pours thin liquid first and sludge last, and neither steams properly.
  2. Add air early and briefly. It takes air less willingly than dairy and the foam is fragile, so introduce it in the first moments and then concentrate on spinning.
  3. Stop cooler than you would with dairy. Many makers of plant drinks advise a lower finishing temperature than for cow's milk. Check the carton, and stop while the jug is comfortably hot, not too hot to hold.
  4. Pour the drink into the coffee slowly, or the coffee into the drink. Bringing the two together gradually avoids a sudden jump in acidity and heat. Letting the espresso stand for a few seconds first also helps.
  5. Serve at once. The foam thins and the drink separates as it stands. This is not a milk to steam ahead.

Sorting out what went wrong

CoffeeHQ explanation

Flecks or curds as it hits the coffee

Usually because: Acidity and heat together have pushed the proteins out of suspension.

Change first: Combine more slowly and a little cooler; if it persists, try a barista version.

Plant milk splitting

Bubbles that vanish in a minute

Usually because: There is too little protein to hold a foam, and no stabiliser in the carton.

Change first: Switch to a carton formulated for coffee.

Milk not foaming

The coffee tastes of almond and little else

Usually because: Almond drink has a pronounced flavour and little fat to carry the coffee.

Change first: Use less of it, or a stronger coffee base.

Allergens and shared equipment

Widely documented

Almonds are tree nuts, one of the common food allergens. If almond drink is steamed with the same jug and wand as other milks, traces carry over. Where anyone with a nut allergy may be served, a separate jug and a thorough wipe and purge of the wand between milks are the usual precautions.

The same applies in reverse: almond drink is not a safe substitute for someone avoiding dairy if the jug has just held cow's milk. Formulations and allergen statements differ by brand and are on the carton.

What to do next

  • Steaming plant milk — The adjustments that apply to every plant drink, with the reasons.
  • Milk frothing troubleshooter — Checks the milk before the technique, which matters most with almond.
  • Oat milk — The plant drink most people find easiest to texture and least likely to split.
  • Soy milk — Much higher in protein, so it builds a firmer foam, with its own splitting risk.
  • Become a barista — A structured programme from dose and grind through milk, drinks and maintenance.

What it is like to work with

Almond drink is mostly water with a small proportion of almond, so there is little protein to build a foam from and little fat to stabilise one. Products sold for coffee compensate with added thickeners and emulsifiers, and the results range from acceptable to a glass of bubbles that vanish. It also carries a pronounced flavour of its own that competes with the coffee rather than sitting under it, which is a matter of preference but should be expected rather than discovered.

How it behaves in the jug

Foaming and holding that foam are different properties, and a milk can be good at one and poor at the other. Ratings are coarse on purpose — the note beside each one carries the actual claim.

  • Foams

    Poorly

    Little protein of its own; whatever foam appears usually comes from added stabilisers.

  • Holds its foam

    Poorly

    Foam tends to be loose and short-lived outside barista formulations.

  • Splitting against espresso

    High risk

    Separates and flecks readily against hot espresso, particularly with lighter roasts.

  • Latte art

    Poorly

    Rarely holds a pattern outside barista formulations.
