Cocoa Powder Guide: Natural or Dutch-Process, and Which to Use

October 12, 2026

Every cocoa powder starts the same way: cacao beans are roasted, ground into a paste and pressed until much of their fat runs out, and the dry cake left behind is ground into powder (the steps before that, from bean to chocolate, are in the bean-to-bar chocolate guide). What happens next splits cocoa into two families. Natural cocoa is left as it is. Dutch-process cocoa, also called alkalized cocoa, is treated with an alkali, a chemical base that cancels out acid. That one step changes the powder's color, its flavor, how well it mixes into liquid and, most important for bakers, how it behaves next to baking soda. The short answer: a recipe that rises on baking soda with no other acid in the bowl needs natural cocoa, because the cocoa's acid is what sets the soda off. A recipe raised with baking powder, or with no leavening at all, works with either, and the choice comes down to color and flavor. The sections below explain why, and end with a way to read any recipe for the cocoa it was written around. What the words cocoa and cacao mean, and where "raw cacao" fits, is covered in the cocoa or cacao explainer.

A few terms first. Nibs are cacao beans cracked into pieces with their shells removed. Chocolate liquor is nibs finely ground into a paste; despite the name, it is a solid or soft paste, not a drink. Cocoa butter is the fat pressed out of that paste. Leavening is whatever makes a batter rise, usually bubbles of carbon dioxide gas. pH is a scale for how acidic or basic something is, explained in section 3.

1. A Dutch invention, 1828

The "Dutch" in Dutch-process is literal. According to a 2015 history of alkalizing by Arlen Moser of Blommer Chocolate, published in the trade journal The Manufacturing Confectioner, Casparus van Houten of the Netherlands patented a cocoa press in 1828, and his son Coenraad developed alkalizing, which was patented in the Netherlands the same year. Van Houten's patent ran out after ten years, and today "Dutched" and "alkalized" mean the same thing.

The same history gives three reasons alkalizing caught on. It reduced bitterness and sourness, which made cocoa more pleasant to drink. It helped the powder disperse, or spread evenly, through liquid. And it darkened the color, which gave the drink the appearance of a more intense flavor.

2. How alkalizing is done

The alkali can go in at three points, Moser explains. It can be applied to the nibs before grinding, the most common method in the United States and Europe, which gives the greatest range of color and usually the finest flavor but typically costs more than the other two. It can be applied to the pressed cake, which treats only the cocoa and not the cocoa butter but limits color development and affects flavor. Or it can be applied to chocolate liquor after grinding, which can be done with limited equipment but also treats the cocoa butter and makes deep reds hard to reach, usually giving a darker brown.

The American Society of Baking's BAKERpedia describes the traditional nib method step by step: the nibs are mixed with a solution of an alkali (its example is sodium bicarbonate) in water, heated long enough for the color to change, then dried below 100°C (212°F) and roasted. The type of bean, the strength of the alkali solution, the pressure and the heating time together decide the final color.

U.S. law sets the menu and the limit. Under the federal standards for cacao products (21 CFR Part 163), the permitted alkalis are ammonium, potassium or sodium bicarbonate, carbonate or hydroxide, and magnesium carbonate or oxide. For every 100 parts of nibs by weight, the total used may not neutralize more acid than 3 parts by weight of anhydrous (water-free) potassium carbonate would. A cocoa made this way must say so on the label: the name is accompanied by "Processed with alkali," or "Processed with" followed by the name of the alkali used.

3. pH, explained plainly

The pH scale runs from 0 to 14, with 7 as neutral, according to the U.S. Geological Survey. Numbers below 7 are acidic; numbers above 7 are basic (also called alkaline). The scale is not evenly spaced in the way a ruler is: each whole number is a tenfold change. Something at pH 5 is ten times more acidic than something at pH 6, and a hundred times more acidic than something at pH 7.

That tenfold rule turns small-looking numbers into large differences. Moser puts natural cocoa at typically pH 5.6, ranging as low as 5.0, and cites a study of 20 commercial cocoa powders by the Hershey Center for Health and Nutrition that measured the pH of natural, lightly, moderately and heavily alkalized powders. He gives black cocoa, the most heavily alkalized kind, a pH of 7.8 to 8.6. The ladder below uses those figures, with the right-hand column worked out from the tenfold rule using the middle of each range.

Kind of cocoa	pH range	Roughly how much less acidic than typical natural cocoa (pH 5.6)
Natural (not alkalized)	5.39 to 5.76	Baseline
Lightly alkalized	6.77 to 7.13	About 20 times
Moderately alkalized	7.21 to 7.52	About 60 times
Heavily alkalized	7.69 to 8.06	About 200 times
Black cocoa	7.8 to 8.6	About 400 times

BAKERpedia's ranges differ slightly (it puts natural cocoa at 5.2 to 5.6 and heavily Dutched cocoa at 7.0 to 8.0), because measurements vary by bean and method. The point holds either way: a natural cocoa carries real acid, and a Dutch-process cocoa carries little or none.

4. Why color and flavor change

Higher pH produces darker color, according to Moser, and the conditions of the reaction steer the shade. Reds come from reacting at about 75 to 85°C (167 to 185°F), with more water in the mix and long, heavy airing both pushing toward red, and a deep red cannot be reached unless some of that color is already in the bean. Browns and blacks come from hotter reactions, about 95 to 125°C (203 to 257°F), sped up by steam or air pressure. BAKERpedia maps the result: natural cocoa is light brown, lightly Dutched cocoa brown, medium Dutched reddish to dark brown, and heavily Dutched red-brown to black.

Flavor follows. Alkalizing smooths sour and bitter undertones into a cleaner, less astringent taste (astringent means the drying, puckering feel of strong tea), Moser writes, and it lets one type of bean be made into more than one flavor profile. Natural cocoa keeps more of the bean's own acidity, which gives it a brighter, more acidic taste.

Valrhona's cocoa powder (shop Valrhona cocoa powder) sits at the reddish end of the Dutch family. The maker describes it as Dutch processed (processed with alkali), with "a very warm red mahogany color," and its product page calls it sugar-free, for baking, dusting and hot chocolate.

5. The leavening question

Here is where the difference stops being cosmetic. Two chemical leaveners matter here, and they work differently.

Baking soda is sodium bicarbonate, an alkaline salt. BAKERpedia explains that it needs heat, acid or both to release its leavening gas, and names acidic partners such as buttermilk, sour cream, vinegar and yogurt. Natural cocoa can play that part too: Moser writes that natural cocoa calls for baking soda as its leavener because soda is set off by acid. Soda also raises the pH of a baked good, and BAKERpedia notes that too much of it can cause yellow or green discoloration and a strong chemical flavor, which with buttermilk can turn soapy.

Baking powder carries its own acid. According to BAKERpedia it contains a bicarbonate, a leavening acid and a filler such as cornstarch that keeps the two from reacting too early. Double-acting baking powder releases gas twice, once during mixing and again during baking. Because the acid comes in the can, baking powder does not depend on the cocoa for anything.

Moser puts the two halves together: an alkalized cocoa with a pH above 7.0 calls for baking powder, because it has too little acid left to activate baking soda. A recipe built on baking soda and natural cocoa counts on the cocoa's acid to set off the soda. Swap in a Dutch-process cocoa, roughly 20 to 200 times less acidic, and that acid is largely gone, leaving soda with less to react with. A recipe built on baking powder brings its own acid, so it does not need any from the cocoa. BAKERpedia adds that in cakes, a higher degree of alkalization gives a darker crust and crumb, greater volume and a more bitter taste.

When a recipe has no chemical leavening at all, the cocoa's acid has no job to do, and either kind works. That is the case in the brown butter cocoa brownies recipe, which uses no soda or powder, so natural and Dutch-process cocoa swap gram for gram and change only color and flavor. Altitude adds its own adjustments to leavened bakes, covered in the cooking at altitude guide.

6. How to read a recipe for its cocoa

When a recipe does not name its cocoa, the leavening list is the best clue.

What the recipe uses	Cocoa it was most likely written for	Why
Baking soda only, with no other acid in the bowl	Natural	The cocoa is the acid the soda needs
Baking soda plus buttermilk or another acidic ingredient	Either, natural safest	Another acid shares the work, but the balance was set with a particular cocoa
Baking powder only	Either, Dutch included	The powder carries its own acid
No chemical leavening (brownies, sauces, puddings, drinks, truffle dusting)	Either	Choose by the color and flavor wanted

On a U.S. label, the federal rule makes this easy to check: an alkalized cocoa must carry "Processed with alkali" or "Processed with" and the alkali's name, such as potassium carbonate. A U.S. cocoa without that statement has not been processed with alkali.

7. Fat content: the other number on the label

Pressing never removes all the fat, and U.S. law sorts cocoa by how much remains. Under 21 CFR Part 163, breakfast cocoa contains at least 22 percent cacao fat; cocoa, also called medium fat cocoa, contains less than 22 percent but at least 10 percent; and lowfat cocoa contains less than 10 percent. Moser notes that pressed cocoa cake is usually alkalized at 10 to 12 percent fat, at the low end of that range.

Category	Fat by weight	Fat in a 30-gram scoop
Breakfast cocoa	22% or more	6.6 g or more
Cocoa (medium fat)	10% to under 22%	3 g to under 6.6 g
Lowfat cocoa	Under 10%	Under 3 g
Valrhona cocoa powder, per the maker	21%	About 6.3 g

Even breakfast cocoa, the richest legal category, holds far less fat than the chocolate liquor it came from, which the same federal standard puts at 50 to 60 percent cacao fat. That gap is why a recipe written for melted chocolate cannot simply trade in cocoa without making up the missing fat. A recipe that calls for bar chocolate wants the cocoa butter that comes with it, as in Valrhona's Guanaja 70 percent fèves (shop Valrhona Guanaja fèves), small chocolate discs whose product page suggests them for baking and melting into ganache (a smooth mix of chocolate and cream). What that 70 measures is explained in the chocolate percentage guide.

8. In a cup

Alkalizing began as a way to improve drinking cocoa, and Dutch-process cocoa still spreads through liquid more easily. Moser is careful about the limit: alkalized cocoa disperses better than natural cocoa but is not completely soluble (it does not fully dissolve), so sediment collects at the bottom over time. He notes that makers add emulsifiers such as lecithin (ingredients that help fat and water stay mixed) and thickeners such as carrageenan to keep the solids suspended.

Not every hot chocolate starts with cocoa powder. Dandelion Chocolate's House Hot Chocolate Mix (shop Dandelion House Hot Chocolate Mix) is, according to its product page, Dandelion's 70 percent chocolate, made with just cacao and sugar and finely ground, rather than cocoa powder, and it is melted into hot milk. How a powder cup and a melted-chocolate cup differ is laid out in the hot chocolate vs drinking chocolate guide.

9. One powder, two chemistries

Natural and Dutch-process cocoa look like a choice of color, and in a brownie with no leavening that is nearly all they are. In a cake raised with baking soda they are a choice of chemistry, because the acid in natural cocoa is part of the recipe's leavening, and an alkali bath that makes cocoa darker and smoother also takes that acid away. A recipe's leavening list is the clue to which cocoa it expects. Read the leavener first, the color second. Explore the other chocolate collection and the baking ingredients collection.
