Six key facts about Coke cans, one pattern: the numbers tell a story of a product that’s cheap, sweet, and carries hidden health costs.

Is a can of Coke 330 ml?

Yes — the standard single-serving Coca-Cola can in Ireland and most of Europe is 330 ml. That’s the size you’ll find in multipacks at Tesco, Dunnes, and SuperValu. According to Coca-Cola’s Irish website (brand’s official product page), the Original Taste is sold in this size across the country.

Is a can of Coke 500 ml?

Yes, 500 ml cans are also available, though they are less common than the 330 ml standard. They are typically sold as individual cans in convenience stores and petrol stations rather than in multipacks. According to ESM Magazine (packaging industry publication), Coca-Cola HBC in Ireland continued offering 500 ml bottles alongside 330 ml cans after the sugar tax was introduced.

How much is 500 ml of Coke?

A 500 ml can of Coca-Cola typically costs between €2.00 and €2.50 when sold individually in Irish convenience stores. Multipacks of 500 ml cans are rare — most multipacks use the 330 ml size. According to Tesco Ireland (major Irish supermarket chain), the 18 × 330 ml pack is the standard bulk option.

The implication: can size directly determines how much sugar you consume in one sitting. A 330 ml can already exceeds daily sugar guidelines for most adults.

Is one can of Coke a day ok?

For most people, one 330 ml can of Coca-Cola per day pushes sugar intake beyond recommended limits. The American Heart Association (leading cardiovascular health authority) recommends no more than 36 g of added sugar daily for men and 25 g for women. A single 330 ml can contains 39 g — already over both limits.

The American Heart Association states: “No more than 36 g of added sugar daily for men and 25 g for women.”

Is 2 cans of coke a day too much?

Two 330 ml cans deliver 78 g of sugar — more than double the AHA’s male limit and triple the female limit. According to the World Health Organization (global public health authority), free sugars should account for less than 10% of total energy intake. For an average adult, that’s about 50 g per day. Two cans exceed that by 56%.

Is 2 cokes a week ok?

Two cans per week (78 g of sugar total) is well within the WHO’s 10% threshold for most adults. The WHO (global health body) recommends limiting free sugars to less than 10% of total energy — roughly 50 g per day. Two cans spread across a week average about 11 g per day, which is safe for most people.

The World Health Organization states: “Free sugars should account for less than 10% of total energy intake.”

Why this matters: the difference between “ok” and “too much” is frequency. Two cans weekly is fine; one can daily pushes most adults over the sugar limit.

What is in a Coke can?

Coca-Cola’s ingredient list is short but dense. According to Coca-Cola’s Irish website (brand’s official product page), the Original Taste contains carbonated water, sugar, caramel colour, phosphoric acid, natural flavourings (including caffeine), and caffeine.

How many calories are in a Coke can?

A 330 ml can of Coca-Cola Original Taste contains 139 calories. That’s according to Tesco Ireland (major Irish supermarket chain), which lists the nutritional breakdown per serving. The calories come entirely from sugar — there is no fat or protein.

Does Coke contain caffeine?

Yes. A 330 ml can of Coca-Cola contains 34 mg of caffeine. The European Food Safety Authority (EU food safety regulator) states that intakes up to 400 mg per day do not raise safety concerns for healthy adults. That means you’d need to drink nearly 12 cans to approach the limit. For context, a standard 250 ml energy drink contains about 80 mg of caffeine, according to a review by the Irish Health Research Board (national health research body).

The pattern: Coke’s caffeine content is modest — about the same as a cup of tea. The real health concern is sugar, not caffeine.

How much is a can of Coke?

Prices vary by retailer and pack size, but the single-can price in Ireland hovers around €1.85. Here’s how the numbers stack up across major Irish supermarkets.

Four price points, one pattern: multipacks slash the per-can cost by more than half, but the deposit system adds a small hidden fee.

How much is a can of Coke at Tesco Ireland?

Tesco Ireland sells an 18 × 330 ml pack of Coca-Cola Original Taste for €4.75, according to Tesco Ireland (major Irish supermarket chain). That works out to about €0.26 per can — a significant saving over the single-can price of €1.85.

How much is a can of Coke at Dunnes?

Dunnes Stores lists a 12 × 330 ml pack of Coca-Cola Original Taste at €12.00, according to the content plan. That’s €1.00 per can — still cheaper than buying singles, but more expensive than Tesco’s bulk deal.

What are the best deals on 24 cans of Coke in Ireland?

Musgrave MarketPlace offers a 24 × 330 ml case of Coca-Cola Zero Sugar, though pricing varies by location. The content plan indicates a 24-pack of Diet Coke at around €19.00 and Original at up to €23.00, depending on the retailer. The deposit system adds roughly €1.80 per multipack.

The trade-off: convenience costs. A single can at a petrol station costs seven times more per ml than a can from a 24-pack at the supermarket.

What is the #1 unhealthiest soda?

There’s no single winner for “unhealthiest soda” — it depends on what you measure. But Coca-Cola is consistently near the top of the list due to its sugar content and lack of nutrients. According to Healthline (health information publisher), a 12-ounce (355 ml) can of Coke contains 140 calories and 39 g of sugar — all from added sugar with no vitamins or minerals.

Is Coke the unhealthiest soda?

Coke is among the unhealthiest, but it’s not alone. Mountain Dew contains more caffeine and similar sugar levels. Pepsi has a nearly identical nutritional profile. The Caffeine Informer (caffeine database) lists Coca-Cola Classic at 34 mg caffeine and 39 g sugar per 12 oz — comparable to most colas.

How does Coke compare to other sodas?

Here’s how Coke stacks up against other popular sodas per 330 ml serving.

Five sodas, one pattern: all deliver 35-45 g of sugar per can — roughly 9-11 teaspoons — with negligible nutritional value.

The pattern: all regular sodas cluster around 140-170 calories and 38-46 g of sugar per can. The real difference is caffeine — and even that is modest compared to energy drinks.

Pros and cons of drinking Coke

The implication: for most Irish adults, the downsides of drinking Coke regularly outweigh the upsides, especially given the sugar content and health risks.
