Umami: The Fifth Taste — and How to Bring it to Your Kitchen

Why does a slow-cooked Bolognese taste so much deeper than a quick tomato sauce? Why does a spoon of Parmesan turn a good soup into a great one? The answer has a Japanese name: Umami — the fifth basic taste alongside sweet, sour, salty, and bitter. Once you understand it, you'll cook differently from now on.

This article explains what Umami is, how it was discovered, which foods contain it — and what techniques and combinations you can use to purposefully bring it into your own kitchen.

What is Umami?

Umami is the fifth basic taste of humans: savory, meaty, deep, and long-lasting. The Japanese word roughly translates to "pleasant savory taste" or "deliciousness." The taste is primarily triggered by glutamate — the salt of glutamic acid, one of the most common natural amino acids — as well as by the nucleotides inosinate and guanylate. The human tongue has its own receptors for all three, just like for sugar or salt.

Umami was discovered in 1908 by Japanese chemist Kikunae Ikeda. He wondered why traditional Dashi broth made from Kombu seaweed tasted so satisfying, even though it was neither sweet, salty, sour, nor bitter — he isolated glutamate from the seaweed and gave the taste its name. Western science took almost a century to catch up: it wasn't until around the turn of the millennium that umami receptors on the tongue were unequivocally proven.

What does Umami taste like?

Umami is harder to name than the other four tastes because it rarely appears alone. The closest descriptions are words like savory, brothy, meaty, well-rounded. Three characteristics are typical: Umami enhances the perceived richness of a dish, it lingers on the palate for an unusually long time, and it makes you crave the next bite. The pure experience is delivered by a piece of aged Parmesan, a reduced tomato sauce, or a clear meat broth — dishes that "taste like more" without being able to pinpoint exactly what.

Which foods contain Umami?

Glutamate is formed wherever protein is broken down — through aging, fermentation, drying, or long cooking. The most important sources:

• Aged cheese — Parmesan is the Western umami champion: the longer it's aged, the more free glutamate it contains.
• Tomatoes — especially ripe, dried, and reduced ones. This is why tomato sauce, tomato paste, and ketchup work as a flavor foundation.
• Mushrooms — especially dried porcini and shiitake, which also provide guanylate.
• Cured and aged meats — ham, salami, air-dried sausage.
• Fish and canned fish — anchovies, sardines, and tuna bring inosinate; the centuries-old Roman fish sauce Garum was nothing more than liquid umami.
• Fermented foods — soy sauce, miso, but also fermented onions like in Vadouvan.
• Seaweed — Kombu, the original source of umami discovery.

The Synergistic Effect: Where Umami Multiplies

The real secret of cooking is not glutamate alone, but its combination: when glutamate and inosinate or guanylate meet, the perception of umami is not additive, but multiplies many times over. This exact effect is behind the great classics of world cuisine — none of them are accidental:

• Tomato + Parmesan — pasta al pomodoro with cheese.
• Tomato + Beef — Bolognese and goulash.
• Kombu + Bonito flakes — Japanese Dashi broth.
• Mushrooms + Meat — any braised dish with porcini mushrooms.
• Anchovy + Tomato — Puttanesca, Pizza Napoli.

How do you bring Umami into your own kitchen?

Four techniques create and enhance umami — without any additives:

• Roasting and Browning: The roasted flavors from searing meat, caramelized onions, or oven-roasted vegetables go hand in hand with umami. The fond at the bottom of the pan is concentrated flavor — always deglaze, never rinse away.
• Give it time: Long braising and reduction breaks down protein and concentrates glutamate. That's why a three-hour Bolognese beats any quick version.
• Use dried ingredients: A few dried porcini mushrooms in a braising liquid, dried tomatoes in a salad, a crushed anchovy in a sauce — small quantities, big impact. You won't taste the anchovy in the finished dish; it only deepens the flavor.
• Combine fermented foods: A teaspoon of fermented seasoning — from Vadouvan to soy sauce — replaces hours of simmering stock in many dishes.

From experience: The quickest umami fix for a bland sauce or soup: briefly roast a teaspoon of tomato paste, simmer a piece of Parmesan rind — or add a pinch of an umami spice blend. The rind, by the way, is the most underrated kitchen scrap ever: it adds depth to any minestrone and is removed just before serving.

Umami seasoning: the shortcut from the factory

If you want the effect in sprinkle form, our range offers two blends specifically composed for umami. The Umami Booster from Altes Gewürzamt combines fermented Vadouvan with tomato flakes and porcini mushrooms — the synergy of glutamate and guanylate sources in one jar. The Gemüseschmackes embeds the same base in a complete vegetable seasoning. Both come from Michelin-starred chef Ingo Holland, who worked with fermentation long before umami was a household name in this country.

The classic pantry items that pair well with these are: Sardines and canned fish for the inosinate side, truffle products for the aromatic peak, and an artisanal ketchup as the quickest tomato-umami source for everyday cooking.

Frequently Asked Questions

What does Umami mean in English?

The Japanese word is best translated as "pleasant savory taste" or "savory deliciousness." There is no exact English equivalent — "savory" comes closest.

Is Umami the same as glutamate?

Not quite: Umami is the taste, glutamate is its most important trigger. Besides glutamate, the nucleotides inosinate (from meat and fish) and guanylate (from mushrooms) also contribute to the umami impression — and mutually enhance each other.

Is glutamate in food a concern?

Glutamate occurs naturally in many foods — from tomatoes to breast milk — and is approved and evaluated as an additive in the EU. Chemically, natural and added glutamate are identical. The cooking methods described in this article do not require any additives anyway: ripening, roasting, and fermentation provide the same taste in a traditional way.

Which food has the most Umami?

Among everyday ingredients, aged Parmesan, dried tomatoes, dried shiitake and porcini mushrooms, anchovies, and soy sauce are leaders. The highest values of all are found in fermented specialty products like fish sauces.

Is there a sixth basic taste?

It is constantly being debated — candidates include "fatty" and the Japanese Kokumi, an impression of mouthfeel and long-lastingness. So far, none of them are scientifically recognized like Umami.

How do I create Umami in vegetarian dishes?

Using exactly the techniques in this article: roasted onions, reduced tomatoes, dried mushrooms, aged cheese, fermented seasonings. A tray of roasted vegetables with a fermented spice blend is barely inferior in depth to a meat broth.
