Why Supermarket Beer Isn’t Always What It Seems

There’s something I’ve started noticing more and more when I’m stood in the beer aisle, and once you see it, you can’t really unsee it.

The same beer isn’t always the same beer.

I don’t mean different batches or different breweries. I mean the exact same brand, same label, same name, sitting next to each other, but actually slightly different depending on how it’s packaged.

The one that really brought it home for me was Hobgoblin Ruby Ale. Pick up a 500ml bottle and it’s 5.0% ABV. Grab a four-pack of cans and suddenly it’s 4.5%. 

Same branding. Same goblin. Different beer.

It doesn’t sound like much, but you can taste it and you can feel it. The canned version feels lighter, a bit easier drinking, and clearly aimed at a different kind of session.

BTW, I'm not saying that this is necessarily a bad thing, if you want the convenience of a four-pack, and want a more sessionable drinking experience, then that perfect, but, if you would prefer the full drinking experience, just check the labels.

If you’re looking for beers that consistently deliver, I’ve put together a guide to good beers you can buy in UK supermarkets that are worth picking up. 

Why the same beer changes

Once you start looking for it, Hobgoblin isn’t the only one.

Bombardier is another good example. Bottle, can, all slightly different strengths. Old Speckled Hen has shifted over time as well, and Spitfire has quietly dropped a bit of strength in the bottle to keep prices sensible.

This isn’t brewers trying to pull a fast one. It’s about how and where the beer is being sold.

Cans are often bought in multipacks, for watching the football, BBQs, or just having a few at home. Dropping the ABV slightly makes the beer more sessionable.

Bottles feel more “premium”. Something you might buy individually, or drink a bit more slowly. So they often keep a slightly higher strength to match that expectation.

It’s subtle, but it’s deliberate.

The quiet rise of lower-strength beers

There’s also been a steady drift towards lower ABV over the last few years, and you can see it most clearly with lager.

A lot of beers that used to sit comfortably around 4% have quietly dropped to 3.4%.

Carlsberg is the obvious one, but it’s not alone. Grolsch, Sol, Banks’s, they’ve all shifted at some point.

That 3.4% mark isn’t random. It sits in a lower alcohol duty tax bracket, which means brewers can keep prices competitive without taking the hit elsewhere.

From a drinker’s point of view, you just get a slightly lighter beer. Not necessarily worse, it's just… different; and sometimes, I personally don't mind it.

Price per litre. This is where it really shows

This is the bit I wish more people paid attention to.

Because while ABV affects how a beer drinks, price per litre affects what you’re actually getting for your money.

Take something like Stella or Peroni. You’ll often see a big multipack of cans working out far cheaper per litre than a single bottle sitting right next to it.

And I mean proper cheaper. Not pennies. Sometimes double the price for the same amount of beer if you buy bottles individually.

As an example, 5% ABV Peroni Nastro Azzurro, as of 23 March 2026, in Tescos (not Clubcard priced):

• 4 x 330ml (bottles) multipack = £5.68 per litre
• 12 x 330ml (bottles) multipack = £5.05 per litre
• 1 x 620ml (bottle) £5.00 per litre 
• 18 x 330ml (bottles) multipack =  £4.42 per litre
• 4 x 440ml (cans) multipack = £4.40 per litre 
• 10 x 330ml (cans) multipack = £4.24 per litre

Cans generally offer better value. Single bottles are generally positioned as “premium” or convenient. Something to grab with your meal. Multipacks are there to get you through the door. But between bottes and cans right now you can save yourself 80p a litre, and in todays economic climate, that's a good saving.

Once you start looking at the little “price per litre” label on the shelf, it becomes very obvious what’s going on.

Cans vs bottles. Not what you might think

I’ll be honest, for years I assumed bottles were better.

They feel better. They look better. They feel like a “proper” drink.

But in reality, cans have a lot going for them.

They keep light out completely, which matters more than people think, especially for hoppy beers. They seal tightly, they chill quicker, and they travel better.

Bottles can still be great, especially for traditional ales, but that idea that cans are somehow inferior doesn’t really hold up anymore.

A lot of the difference is just perception.

What I check now before I buy

None of this has put me off supermarket beer. If anything, it’s made me better at buying it, and these days, I tend to do a quick mental checklist.

• ABV. Is it what I expect?
• Format. Can or bottle, and does it suit the style?
• Price per ml. Am I actually getting value here?
• And finally, the style itself. Some beers just cope better with supermarket life than others.

Stouts, traditional ales, and lagers tend to be safe bets. Big, hop-heavy beers can be more hit and miss unless you know they’re turning over quickly.

It’s not a trick. It’s just how it works

Supermarkets have made beer more accessible than it’s ever been. You can walk into Lidl, Tesco, Asda, and pick up a genuinely good beer for a couple of quid.

But the trade-off is that things get tweaked. Strength, format, pricing, all adjusted to fit how people actually buy and drink.

Once you know that, you stop being surprised by it.

In fact, you start using it to your advantage.

Because the beer aisle hasn’t got worse ... it’s just got more complicated.
