How many calories are in a pint of Guinness?

A pint of Guinness Draught (568ml at 4.1% ABV) contains approximately 199 kcal. This is actually lower than many popular lagers — a pint of Stella Artois is around 227 kcal and Peroni is about 235 kcal. Per 100ml, Guinness Draught has roughly 35 kcal. The Nigerian Foreign Extra Stout variant is much higher at 66 kcal per 100ml (roughly 375 kcal per 600ml bottle) due to the higher alcohol content of 7.5% ABV.

Is Guinness healthier than lager?

Guinness Draught is lower in calories per pint than most standard lagers (199 kcal vs 220-250 kcal for typical 4-5% lagers). It is brewed from just four natural ingredients with no artificial additives, while some lagers use additional processing aids. Guinness also contains small amounts of B vitamins and antioxidants from the roasted barley. However, 'healthier' is relative — it is still an alcoholic drink with no essential nutritional value, and any health benefit from ingredients is vastly outweighed by the metabolic cost of alcohol.

What is the nutrition in Guinness 0.0?

Guinness 0.0 is the alcohol-free version (less than 0.05% ABV). While Tesco does not list detailed nutrition on its product page, Guinness states it contains approximately 17 kcal per 100ml — about half the calories of regular Guinness Draught. A 440ml can would be roughly 75 kcal. Without alcohol, you remove the main metabolic concern of beer. The ingredients include water, malted barley, hops, roast barley extract, and yeast — similar to regular Guinness but with the alcohol removed after brewing.

Nutritional Information for Guinness

Q: What is the glycemic index of guinness?

Guinness has a glycemic index of 40, which is classified as Low GI. Beer generally has a moderate GI due to its maltose content, but Guinness is relatively low in residual sugar â€” most sugars are consumed during fermentation. The main metabolic concern is alcohol itself: the liver prioritises alcohol metabolism over everything else, which can temporarily impair blood sugar regulation. A pint of Guinness contains roughly 17g of carbohydrate, which will produce a mild glucose response. The bigger issue is what alcohol does to appetite and food choices â€” people tend to eat more (and less healthily) when drinking.

Guinness Draught contains approximately 35 kcal per 100ml (about 198 kcal per pint), making it one of the lower-calorie beers by volume. It is brewed from just four core ingredients — water, malted barley, hops, and yeast — which places standard Guinness at NOVA 2 (processed culinary ingredient). The alcohol itself is a significant calorie source with no nutritional benefit. Guinness 0.0 offers a zero-alcohol alternative, though Tesco's product pages provide limited nutrition data for most Guinness lines.

Processing level

NOVA 2 (processed culinary ingredient)

Standard Guinness (Draught, Original) is brewed from water, malted barley, roasted barley, hops, and yeast — all natural ingredients subjected to traditional fermentation. Under NOVA classification, beer is categorised as NOVA 2 because the brewing and fermentation process transforms the raw ingredients into a fundamentally different product. There are no ultra-processed additives, no flavourings, no colourings — the dark colour comes from roasted barley. Guinness Nigerian Foreign Extra Stout at 7.5% ABV is the same classification but with significantly higher alcohol and calorie content (66 kcal/100ml).

What to watch for when shopping

Guinness is one of the simpler beers ingredient-wise — no artificial additives or colourings. The main health consideration is alcohol itself: at 4.1-4.2% ABV for standard Draught/Original, a pint delivers about 199 kcal with virtually zero nutritional benefit. Nigerian Foreign Extra Stout at 7.5% ABV is significantly stronger — 66 kcal per 100ml, or roughly 375 kcal per 600ml bottle. Guinness 0.0 removes the alcohol and most of the calorie concern, though Tesco does not list detailed nutrition for it. Note: most Guinness products on Tesco's website have incomplete nutrition panels, likely because alcohol is exempt from mandatory nutrition labelling in the UK.
