Dunkel: The Dark German Lager

Dunkel is Munich's dark lager, and the single most important thing to know about it is that it is not a strong beer and not a roast-heavy beer. It is an ordinary-strength lager, usually around four and a half to five and a half percent, that gets its colour and its sweetness from the malt rather than from the roast, which is why it pours a deep chestnut to dark brown and tastes of bread crust, caramel and toasted grain instead of coffee or treacle. It is the darker half of the Munich tradition, sitting beside the pale helles in exactly the same way, and it is the beer to reach for when you want a full bodied German lager that still drinks clean and finishes with only a whisper of sweetness. What separates it from a bock, which is the version people most often confuse it with, is strength and little else, and that is a distinction worth drawing once rather than endlessly.

What To Know Before Ordering A Dunkel

• Check the strength on the label, because a dunkel sits under about five and a half percent.
• Serve it slightly cool rather than ice cold, because the malt recedes when the glass is too cold.
• Expect bread crust and caramel rather than coffee, since the colour comes from kilned malts and not from roast.
• Pair it with roast meats or hard cheese, because its moderate strength does not overwhelm anything.

Where The Name Comes From

Dunkel is simply the German word for dark, and the style takes its name from the obvious fact that it is the dark beer of its home city. Munich sits at the centre of the Bavarian lager tradition, and for centuries the city's brewers made both a pale and a dark version of the same underlying beer, sold side by side, with the pale one becoming helles and the dark one becoming dunkel. The tradition is protected as a regional product in Germany the way Kolsch is in Cologne, so the name carries a sense of place and a colour at once. The reason the style spread beyond Bavaria at all is that Munich's dark lager is one of the very few German lagers that was deliberately exported in large quantities in the twentieth century, and much of what the wider world thinks of as German lager, the dark half included, was formed by that export.

The Malt Is The Whole Style

If you take one thing away from a dunkel, it is that the flavour comes from kilned dark and caramelised malts rather than from anything scorched. A brewer building the grist for a dunkel leans on Munich and Vienna malts for the body and on darker kilned and caramel malts for the colour and the sweet bread crust note, and it does not push any of it into the heavily roasted range that a porter or a stout uses. That restraint is what keeps the beer clean. Because the malts are kilned rather than roasted, the sweetness in a dunkel is a malt sweetness, a toasty caramel roundness, and it is not the sharp, charred bitterness of a dark roast. The colour is deep, but the flavour underneath it stays in the family of bread and biscuit, which is why a dunkel can be full bodied and still easy to drink.

The beer is bottom fermented and then cold conditioned for weeks, the same lagering every German lager gets, and that step is what lets it settle into a smooth, clean drink despite the dark grist. The hops are restrained, used for a light noble hop aroma rather than bitterness, so the finish is more about the malt and a faint hop dryness than about hops. The result is a beer that reads as bigger than its strength in the first sip and then proves, over the next few, that it is a lager and not a heavy ale.

Dunkel And Bock, The One Difference That Matters

The comparison with bock comes up constantly, and most of it is confusion rather than real disagreement. A Munich dunkel and a Munich dunkelbock share the same dark malt base and the same kind of toast and caramel flavour, and they are brewed in the same region by the same breweries, so they genuinely are close relatives. The difference is strength. A dunkel is an ordinary-strength lager, usually under about five and a half percent, while a bock is a stronger, fuller lager, usually six percent and up, and the extra alcohol gives a bock more body and a heavier, more lingering finish. That is essentially it. If the beer in front of you is under five and a half percent and drinks like a lager, it is a dunkel; if it is stronger and fuller, it is heading toward a bock. Our fuller write-up of the bock family covers the stronger end and the seasonal versions, but the boundary you need is simply the strength line and the two names sit on either side of it.

What It Tastes Like In The Glass

Pour a dunkel and expect a deep chestnut to dark brown beer with a substantial, creamy, off-white head that stays around as you drink. The aroma is bready and slightly sweet, like fresh toast or caramel, with a faint note of dried fruit underneath. The taste is full and malty through the middle, sweet but not syrupy, with that toasted bread and caramel character sitting right at the front, and it finishes with only a light bitterness and a faint sweetness that does not cloy. It is a bigger, warmer, toastier beer than a helles without being a strong or heavy one, and the contrast between the two is exactly why a Munich brewery offers both. Served slightly cool rather than ice cold, around seven to nine degrees Celsius, it shows all of this; served too cold the malt recedes and you are just tasting a dark lager.

Dunkel is also the one dark German lager that is genuinely easy to pair with food without effort. Its toast and caramel respond well to roast meats, sausages, hard cheeses and pretzels, and its moderate strength means it does not overwhelm anything, which is a more useful everyday property than its reputation for being a novelty dark beer suggests.

Where To Find It In British Columbia

A genuine Munich dunkel is one of the easiest German styles to find well made, because it is a standard export for Bavarian breweries and a core product for many of them. You will find it in any store that stocks German lagers, and the Bavarian and Munich producers are the ones whose version is worth asking for. If a shop carries a German dark lager, read the style line: a dunkel, a Munich dunkel or a dunkelbock is what you want, and a Schwarzbier, which is a darker, leaner and more bitter German black lager from further north, is a different style that drinks noticeably thinner. The broader question of how dark lagers fit together is covered in our piece on what dark lagers are, but within the dark German lager family the dunkel is the one defined by sweet toasted malt at ordinary strength, and that is the beer to look for.

Kolsch: The Cologne Beer Nobody Can Agree On

Kolsch is the beer of Cologne, and the argument about it has never really stopped. It is brewed with top fermenting yeast at ale temperatures, which makes it an ale by the method a brewer uses, and it is then conditioned cold for weeks the way a lager is, which makes it a lager by the way a brewery finishes it. It is pale gold, heavily carbonated, soft in the middle and dry at the end, and it is served in a narrow 200 millilitre straight-sided glass that is unlike anything else on a German bar. In 1906 a law passed in Germany defined what could legally be called Kolsch, spelling out the recipe and the method, and the name was later reserved to the Cologne area, which is why a genuine bottle carries that place on it. Everything else about the style, including whether it counts as an ale or a lager, has been argued over ever since.

What To Know Before Ordering A Kolsch

• Read the strength first, because anything at six percent or above is not what the style is meant to be.
• Order it in a 200 millilitre Stangen if you can, because the glass is built around how the beer is drunk.
• Ignore the ale versus lager argument, because the method tells you more than the label does.
• Look for the place of origin on the bottle, because the name is a protected regional claim.

The Hybrid Fermentation

The word hybrid is doing real work here, because the two halves of the process are genuinely different from each other. The wort is pitched with a Saccharomyces cerevisiae strain, the top fermenting house yeast used across German brewing, and it ferments warm in the range an ale uses, developing the esters and the clean, slightly fruity character that comes from that family of yeast. Then, once the ferment is done, the beer is moved into cold storage for a lagering period of several weeks, during which the yeast drops out and the liquid clears. A lager uses a single cold ferment from the start and a lager yeast, and an ale never gets the cold rest. Kolsch does both, in that order, which is why it tastes cleaner and smoother than a typical ale of the same strength but keeps a little more life than a typical lager.

The grist is correspondingly unusual. It is mostly Pilsner malt, with a small proportion of lightly kilned malt added for a touch of grain, and the mash is run hot enough to leave the beer a little more body than a lager would have. The hops are German, traditionally Hallertau, used gently and for aroma rather than for aggressive bitterness, which is why a Kolsch finishes dry and clean rather than grassy. The alcohol sits low, usually around four and a half to five percent, and the carbonation is deliberately high, high enough that the beer foams into a substantial white head the moment it hits the glass and keeps that head for the length of the pour.

The 1906 Law And What It Actually Fixed

The history of Kolsch is really the history of Cologne trying to protect a beer that drinkers were copying all over the place. German legislation passed in 1906 set out a legal definition of the style, specifying the ingredients, the top fermentation and the cold maturation, and it treated the name as a geographical claim attached to the Cologne area rather than a generic term for any light golden German ale. That protection is why you see the word used tightly. A brewery in Cologne can call its beer Kolsch, and a brewery anywhere else in the world can produce something that tastes like Kolsch, but calling that product Kolsch is a different matter and the naming is handled differently depending on where you are. This is a common pattern in European food and drink law, where a name that started as a local product eventually becomes a protected regional designation, and it is the reason the bottle tells you more about origin than the style line on it does.

It is worth being careful with the legal details, because the exact scope has been revised and interpreted more than once, and anyone who tells you the 1906 law means a specific thing today without checking the current text is guessing. What is not in doubt is the shape of it. The law exists, it defines the beer by method and by place, and the place part is what causes the disagreement that follows.

Why The Classification Keeps Changing

The classification problem is not really a mystery. Kolsch is defined by a method that belongs to one half of brewing and a finish that belongs to the other, so any system that sorts beer by one axis has to put it somewhere slightly wrong. In Germany the answer is settled by the law, and it is simply its own thing. Outside Germany, style guidelines and rate your listings have each taken their own position, and they have changed their minds over the years, moving the beer between the ale and the pale German lager columns depending on which criterion they weight more heavily. The sorting is inconsistent enough that you will find the same bottle described two different ways in two different places, and neither description is a mistake.

The practical answer for you at the shelf is to ignore the ale versus lager argument and read the method instead. If a beer was fermented warm with a top fermenting yeast and then cold conditioned, it is doing what Kolsch does, whatever the label calls it. That also tells you what to expect, because a genuine Kolsch is a clean, bright, quick drinking beer at low strength, and it should never taste heavy, roasty or boozy. A dark beer marketed as a Kolsch is not a mislabeled lager, it is a different beer entirely.

Tasting It And The Glass It Comes In

Pour a Kolsch into the glass it was designed for and much of the argument dissolves, because the glass is built around how the beer is meant to be drunk. The Stangen, which is what the tall straight glass is called, holds a narrow 200 millilitre, far less than a pint, and it is meant to be filled completely so that the head reaches the rim. The beer is then drunk quickly rather than sipped, which suits a light, fizzy, low strength lager far better than a slow glass would, and the fresh empty Stangen appearing at the bar counter is a small ritual that says the glass has to be returned and refilled rather than nursed. You will see the beer served in a large stemmed tulip or a flute in most of the world outside Cologne, and you can drink it perfectly well that way, but the small straight glass is the style's native form and the carbonation behaves differently in it.

In the glass it is a clear pale gold, more golden than a pilsner, with a white head that clings to the walls. The nose is light, slightly grainy and floral. The taste is crisp, gently bready in the middle, lightly bitter from the hops, and it finishes dry and clean, with the carbonation carrying the whole thing. It is very easy drinking, and at under five percent it is one of the most useful beers for a long afternoon. It also sits close to a pilsner on a table without duplicating it, because the top fermentation gives it a rounder, slightly softer centre that a pilsner does not have, and that difference is the whole reason to order it instead.

Where To Find It In British Columbia

An authentic bottle from the Cologne area is something you will find in a specialty import shop in Vancouver or Victoria rather than in a general bottle shop, and the good labels carry the place of origin and the protected name. Expect to pay a premium for a genuine one, because a style this tightly defined by geography cannot be produced at scale outside the region and the ones sold under the name are limited. On a tap list you are more likely to see a brewery making a Kolsch in the method rather than one selling a certified bottle, and that is worth trying, because the method is the part that is actually reproducible. Read the strength first: anything at six percent or above is not what a Kolsch is meant to be, whatever the ale and lager columns say about it.
