What are stouts and porters?
Stouts and porters are classic British ales and the most distinctive-looking beers on the bar, pouring dark browns and black with a creamy white foam. It’s the grain used for the beer that gives the colour (and a lot of the flavour), and thinking about what happens in cooking helps explain the process better.
Barley is the main brewing grain, with wheat and oats also common. Barley needs to be turned into malt before it’s brewed with, and a key part of that process happens in a kiln, where the grain is roasted. As with a slice of bread under the grill, the longer the grain is cooked, the darker it gets – it’s the same Maillard/browning effect. The kiln is where a lot of beer’s base flavours come from, and it’s no coincidence that many of them are reminiscent of the bakery or coffee shop: bread, biscuit, tea, toast, marmalade, caramel, dried fruit, chocolate and coffee.
Chocolate and coffee flavours
There are dozens of different types of malt, and for each recipe a brewer usually combines pale base malts (providing the sugars that ferment into alcohol) with more highly kilned malts to add flavour and colour. In a stout or porter, only around 10% of the malts will be roasted, but that’s enough to create a dark beer with a chocolate or coffee-like flavour – think of it like a chocolate cake recipe, where a relatively small amount of cocoa is used compared to the rest of the ingredients.
Did you know?
There’s a misconception that a pint of Guinness or other stout is as calorific as a roast dinner. Calories in beer mostly come from the alcohol, regardless of style, so a pint of 5% lager (230kcal) contains more calories than a 4% stout (200kcal, similar to a glass of wine). But who’s counting?
