The Stout Fellow's Guide to Dark Beers Porter, stout and what the label means

A dark beer need not be heavy, sweet or especially strong. Colour tells you something about the malt; it does not tell you everything about the body or the ABV. The most useful clues are the style, the brewer's description and the ingredients. Here is a short route through the darker end of the shelf, without pretending that every black can contains pudding.

Porter and stout: a shared history

Porter emerged in London in the early 1700s. The Beer Judge Certification Program (BJCP) describes English porter as a predecessor of stout, which was once called “stout porter”. Today's labels are not a strict strength ladder. A modern porter can be fuller or stronger than a stout; check the beer in front of you rather than relying on the name alone.

English porter often has bready, toasty, chocolate or caramel malt notes, with a range of bitterness and body. Those are style characteristics, not tasting notes for every porter on sale.

Five labels worth knowing

Style	What its style description suggests	What to check
English porter	Toast, chocolate and sometimes caramel, with a lighter body than many expect	Actual ABV and sweetness; modern versions vary
Irish stout	Roasted, often coffee-like and dry; a draught nitro pour can add creamy texture	Can, bottle or draught dispense changes the experience
Oatmeal stout	Oats can contribute a fuller, smoother mouthfeel	Ingredients and sweetness vary
Sweet or milk stout	Sweeter balance; lactose may be used	Milk sugar matters for anyone avoiding dairy or animal ingredients
Baltic porter	Often stronger and malt-rich, commonly brewed with lager yeast	ABV and pack size before treating it like a session beer

The BJCP guidelines describe families of beer for judging, not a promise that every commercial example will fit neatly. Brewers can reinterpret them. “Dark” also includes other styles, such as schwarzbier, a dark lager with a comparatively light body.

Choose by the result you want

For a drier roasted profile, begin with Irish stout. For toasty malt and a range of strengths, look at porter. If you want more body, oatmeal stout is a useful label to investigate; if sweetness is the goal, inspect a sweet stout's ingredients. Baltic porter is a different proposition in strength, so read the ABV before ordering a large pack.

Food can be a useful way to explore the differences: roast notes may echo chocolate, while a drier beer may contrast with a sweet dessert. Our beer and food pairing guide offers a simple way to test that idea. If you are buying alcohol-free dark beer, check the stated ABV and ingredients on the specific product; our alcohol-free mixed-case guide includes an example outside its comparison boxes.
