The short answer: a “forty beer can” is a 40‑ounce (1.18 L) aluminum can, the largest single‑serve format most breweries offer today.
That fact changes the game for anyone who thought cans were only 12‑ or 16‑ounce vessels. A forty beer can packs the volume of a pint glass plus a half, but with the portability, chill‑time, and environmental edge of a can. It’s not a novelty; it’s a growing segment of the market that lets craft brewers serve big‑flavor, high‑ABV styles without the heaviness of a bottle.
What is a forty beer can?
The term simply describes the size: 40 ounces, or roughly 1.18 liters, of liquid in a single aluminum container. Most of these cans are made from the same recyclable material as standard 12‑ounce cans, but they’re engineered with thicker walls and a reinforced lid to handle the extra pressure from higher‑alcohol beers and the weight of the larger volume.
Because the can is a sealed, light‑proof environment, it protects delicate hop aromatics and prevents oxidation, which is why many hop‑forward IPAs, barrel‑aged stouts, and even sour ales are now being released in this format. The larger size also means a better cost‑per‑ounce ratio for both the brewer and the consumer.
How is a forty beer can made?
Manufacturing a forty beer can starts with the same aluminum coil that feeds standard cans. The coil is fed through a high‑speed press that stamps out a blank, then forms the body, adds a ribbed grip, and seals the bottom. The key differences are the dimensions of the die and a slightly higher gauge of aluminum (usually 0.012‑0.013 inches versus 0.010 for a 12‑ounce). This added thickness gives the can the strength to hold more liquid and endure the higher internal pressure of strong beers.
After forming, the cans travel through a cleaning line, then a coating line where a food‑grade varnish is applied inside to prevent metal‑taste. The exterior receives a printable surface that can hold intricate artwork—perfect for the eye‑catching graphics that dominate craft beer shelves. Finally, the cans are shipped to a bottling line where they’re filled, capped with a pressure‑rated lid, and inspected for leaks.
Popular styles you’ll find in a forty beer can
Brewers aren’t just blowing up their regular lagers into larger cans; they’re using the format to showcase styles that benefit from extra volume:
- Double‑IPA / Imperial IPA – The extra ounces let drinkers enjoy the full hop profile without having to open multiple cans.
- Barrel‑aged Stout or Imperial Stout – These high‑ABV, complex beers stay smoother longer in a sealed can, and the size mimics a small bottle.
- Sour & Wild Ales – The larger container reduces the “over‑acidic” bite that can happen when you finish a small can quickly.
- Sessionable Pale Ales – For a low‑ABV brew, a forty can offers a satisfying pour without the guilt of a full pint.
Because the can keeps the beer cold longer than a glass, many drinkers report that the flavor stays brighter over the course of a gathering.
What to look for when buying a forty beer can
Not all forty cans are created equal. Here’s what seasoned can‑drinkers check before popping the tab:
- Seal Integrity – Give the can a gentle squeeze; it should feel firm, and the lid should not wobble.
- Label Quality – High‑resolution artwork often signals a premium brand that invested in proper can printing.
- ABV & Style – A 12‑ounce IPA at 7% vs. a 40‑ounce Imperial Stout at 12% will feel very different. Know what you’re after.
- Carbonation Level – Some breweries over‑carbonate larger cans, leading to a “gassy” mouthfeel. Look for reviews that mention a balanced fizz.
And don’t forget to check the freshness date. Because cans are airtight, the “best before” window can stretch up to six months for most beers, but for hop‑intense brews, a shorter window preserves aroma.
Common mistakes people make with forty beer cans
Most articles on the topic praise the size but skip the practical pitfalls. Here are the three biggest errors drinkers actually make:
1. Treating a forty can like a bottle
Because it feels heavier, many reach for a wine‑glass‑sized pour, but the can’s interior pressure is calibrated for a full pour. Pouring too quickly can cause excessive foam, wasting beer and flattening the flavor.
2. Assuming all cans are equally recyclable
While aluminum is recyclable, the thicker gauge of a forty can requires a different processing stream in some municipal programs. Check your local recycling guidelines before binning them with regular cans.
3. Ignoring temperature dynamics
A larger volume takes longer to chill, but once cold, it stays colder. Many drinkers chill a forty can for the same 30 minutes they’d use for a 12‑ounce, ending up with a lukewarm beer. Aim for at least an hour in a cooler or a dedicated beer fridge.
How the forty beer can fits into modern marketing
Beyond the functional benefits, the format is a canvas for bold branding. Breweries can showcase expansive artwork that tells a story across a larger surface.

The larger label area often becomes a collector’s item, driving repeat purchases.
Verdict: Which drinker should choose the forty beer can?
If you value flavor stability, want a better price per ounce, and enjoy sharing a single container with friends, the forty beer can is the clear winner. For the casual sipper who prefers a quick, single‑serve experience, a standard 12‑ounce may still be preferable. But for anyone chasing bold hop punch, barrel‑aged depth, or just the convenience of a portable “pint‑size” brew, the forty can outperforms on taste, economics, and sustainability.
Bottom line: the forty beer can isn’t a gimmick—it’s a practical, flavor‑preserving format that’s reshaping how craft beer is packaged and enjoyed.
