As the weather cools and the nights draw in, beer lovers start swapping their golden lagers for something more wintry. Sales of stout and porter begin to rise as drinkers seek something more filling, more warming – but do dark ales really deliver or is it all in our minds? Lucy Corne delves into a six-pack of dark beer facts and myths.
Dark beer isn’t necessarily higher in alcohol
There is a common misconception that dark beers are boozier than their golden counterparts. While there are indeed stouts and porters that are best sipped sitting down, you’ll also find plenty of black-hued brews that are considered “session strength”. Look at the most famous of them all, Guinness, which measures in at 4.2% ABV – only mildly stronger than Castle Lite.
There could be more calories in your lager than your stout
That line about stout being a “meal in a glass”? It’s mostly down to marketing genius. For many years Guinness – perhaps the greatest marketers of all time – shouted about the, well, stoutness of their stout. “Guinness is good for you,” they boasted. “Guinness gives you strength.” But in fact, Guinness – and other dry stouts in the same alcohol range – actually contain less sugars, and therefore fewer calories, than a pint of standard strength golden lager. Of course, people’s perceptions play a role here too and there’s something about a mahogany-coloured pint topped with dense, fluffy foam that makes you feel full just by looking at it …
Dark beers begin with pale malts
It is malted barley that gives beer its colour. Once malted, the barley is roasted to different degrees and comes in shades that range from pale beige to the deep, deep brown of coffee beans. But even the darkest of stouts begins with the palest of malt. Malt also provides the sugars required to make alcohol as dark roasted malts simply can’t to the job by themselves. In fact, upwards of 80% of the malt used in a porter or stout is pale malt, with the remainder still managing to give the colour and flavours – including dark fruits, coffee and chocolate – that you expect in your pint of dark ale.
I keep saying ale, but in fact dark beers could just as easily be lagers. The difference between the two comes down to yeast, not malt, and there are many dark lagers. The German Schwarzbier is tough to find in South Africa but worth seeking out for its bready, chocolaty goodness. Castle Milk Stout is actually produced with a lager yeast , and perhaps most surprisingly of all, the high-alcohol Baltic porter – a rich winter warmer – is actually traditionally brewed as a lager.
That thing about breastfeeding? It’s a myth
When I just had my son, I can’t tell you the number of times people recommended a pint of milk stout to help with breastfeeding. It’s a myth. Alcohol inhibits breast milk production. And while on the topic of milk – there’s no milk in milk stout either! The name actually comes from the addition of lactose – also known as milk sugar – to the beer. Lactose is non-fermentable and so leaves a subtle sweetness and a little extra body in the finished stout.
