Malted chocolate drink powder

Malted drink powders are built on malted barley extract, wheat flour and milk solids, with cocoa added in the chocolate versions. The proportions matter to how the drink tastes: cocoa is generally a minority ingredient, and the dominant flavour is malt.

Malting germinates barley and halts it, converting starch into maltose and other reducing sugars and mobilising amino acids. Drying the extract runs Maillard reactions between the two, generating pyrazines, furans and Strecker aldehydes. Those are the same aroma families roasting produces in cacao, which is why malt and chocolate combine so seamlessly — they are not two flavours that happen to suit each other, they are two outcomes of closely related chemistry.

The category has two quite separate cultural lives. In Britain and several Commonwealth countries these are bedtime drinks, made with hot milk, and the association is old enough to be part of what the products mean. In the United States the same powder is a soda-fountain ingredient, added cold to milkshakes. It is the same chemistry at two temperatures.

No cocoa percentage is declared and none would be informative. The ingredient list is the useful thing: where cocoa sits relative to malt extract, sugar and milk powder tells you what the drink will taste of.

Toasted grain and caramel first, with cocoa giving colour, bitterness and depth underneath. Distinctly savoury at the edge in a way plain cocoa is not.

Contains starch as well as cocoa, so it clumps at least as readily and the clumps are held together by gelled starch. Paste it first. Do not boil: malt aroma is volatile and a boiled drink is noticeably flatter and sweeter.
