Back to the Cocoa Powder Guide
Natural cocoa powder is mildly acidic, with a pH of about 5.3 to 5.8. Dutch-process (alkalized) cocoa is neutral to slightly alkaline, at about 6.5 to 7.6 or higher. That one difference explains why recipes care which cocoa you use and which leavening goes with it.
For comparison, plain water sits at pH 7, and natural cocoa is far less acidic than lemon juice or vinegar; it simply leans to the acidic side, enough to react with baking soda in a batter.
Nobody thinks of cocoa as an acidic food until a cake fails to rise. The acidity is mild, you cannot taste it as sourness, and yet it is the hinge on which a whole category of chocolate baking turns, because baking soda needs an acid to work and natural cocoa quietly supplies one. Here is the pH of each kind of cocoa, what it does in a batter and in a mug, and a thirty-second kitchen test to find out which one is in your tin.
What is the pH of each type of cocoa powder?
A 2008 survey of commercial cocoa powders by Miller and colleagues sorted them by extractable pH, the measure manufacturers use. Natural, non-alkalized cocoa came in at about 5.3 to 5.8: light reddish brown, bright and fruity. Lightly alkalized cocoa sat at about 6.5 to 7.2, medium brown and mellower. Medium alkalized ran about 7.2 to 7.6, darker and smooth. Heavily alkalized cocoa, the black cocoa of dark sandwich cookies, came in above 7.6, near black and very mild. Alkalizing, also called Dutch-processing, treats the cocoa with an alkaline solution to raise its pH, and the same step darkens the color and softens the flavor. The full comparison is in natural vs Dutch-process cocoa powder, and black cocoa powder shows the far end of the scale.
Why does cocoa acidity matter in baking?
Because acid and baking soda make bubbles. Baking soda is an alkali, and it only releases carbon dioxide, the gas that lifts a cake, when it meets an acid in the batter. Natural cocoa supplies some of that acid, which is why so many classic American chocolate cakes list baking soda and natural cocoa and nothing that looks sour. Dutch-process cocoa cannot do that job, so recipes built on it rely on baking powder, which carries its own acid. Iowa State University Extension’s rule of thumb covers it: natural cocoa with baking soda, Dutch-process with baking powder. Recipes that use both leavenings, or that contain buttermilk or yogurt, have acid from elsewhere and take either cocoa, and recipes with no leavening at all, sauces, drinks and frosting, let you choose by flavor and color.
What happens if you swap one cocoa for the other?
Natural cocoa in a Dutch-process recipe that uses only baking powder bakes fine, with a slightly lighter color and a brighter, fruitier chocolate taste. Dutch-process cocoa in a natural-cocoa recipe that uses only baking soda is the one that goes wrong: there may not be enough acid for the soda, so the crumb turns out denser and the unreacted soda can taste soapy. A spoonful of buttermilk or yogurt in place of some of the liquid brings the acid back. For what to do when you run out altogether, see cocoa powder substitute.
Does acidity change the taste of a cocoa drink?
Yes, and in a good way for many people. Natural cocoa tastes brighter, with fruity and slightly sharp notes that come from the acids fermentation created in the bean; Dutch-process tastes rounder and more mellow because those acids have been neutralized. In hot chocolate both work, and a pinch of salt and a little sugar balance natural cocoa beautifully, as in our hot chocolate with cocoa powder.
How do you tell natural from Dutch-process cocoa?
Read the label first: Dutch-process cocoa lists cocoa processed with alkali in the ingredients, while natural cocoa lists only cocoa. Look at the color: natural is lighter and reddish brown, Dutch-process darker and more even. Then, if you want to be sure, try the fizz test. Stir a teaspoon of cocoa and a pinch of baking soda into a little warm water. Natural cocoa fizzes gently as the acid meets the soda; Dutch-process cocoa barely reacts. It takes thirty seconds and settles the question for good. The labeling side of cacao versus cocoa is in cacao vs cocoa powder.
Where does Grevista cocoa fit?
Grevista is a natural, non-alkalized cocoa powder made from Vietnamese Trinitario cacao, with a single ingredient. That makes it the natural-cocoa choice for recipes that use baking soda, and it gives drinks the brighter, fruitier character natural cocoa is known for. Compare the box sizes on the Grevista cocoa powder page.
To put this into practice when you shop, see our guide to the best cacao powder, which compares options by processing, flavor and published heavy-metal testing.
Frequently asked questions
Is unsweetened cocoa powder acidic?
Natural unsweetened cocoa is mildly acidic, at about pH 5.3 to 5.8. Unsweetened Dutch-process cocoa is neutral to alkaline.
Is cacao powder acidic?
Cacao powder is natural (non-alkalized) cocoa under another name, so it sits in the same mildly acidic range.
Is Dutch-process cocoa alkaline?
Lightly alkalized cocoa is close to neutral; medium and heavily alkalized cocoas are slightly alkaline, above pH 7.
Does acidic cocoa upset your stomach?
At a pH of 5.3 to 5.8 cocoa is far less acidic than orange juice or coffee, and most people notice nothing. If acidic foods bother you, Dutch-process cocoa is the milder choice.
