The age-old debate of canned beer vs. bottled beer continues to stir up conversations between both brewers and drinkers. Some swear by the crisp refreshment of a bottle, while others love the convenience and portability of a can. But is one actually better than the other, or is it only a matter of opinion? Diebolt Brewery coming to you live with answers. 

What Are the Advantages of Canned Beer vs Bottled?

Cans are to beer what the twist top is for wine. Snobs still look down their nose at a screw top, but it makes too much sense to ignore. Unlike a cork, no air can get in, and resealing is super easy. A twist of a cap is infinitely preferable to trying to wedge the cork you destroyed with the opener back into the bottle. PRACTICAL, is what we’re saying.

When it comes to beer, cans are also PRACTICAL for even more reasons than an airtight seal: 

1. Canned Beer Makes For Better for Freshness & Quality

• Blocks Light Exposure: Cans prevent light from reaching the beer, which reduces the risk of skunky flavors  caused by UV exposure.
• Less Oxygen Contamination: Again, cans are sealed more tightly than bottles, which means less possibility of oxidation that can affect the taste over time.

2. Canned Beer Is Lighter & More Portable

• Easier to Transport: Cans are lighter than glass bottles, so they are easier to carry and ship. This means they are also usually cheaper than bottles. 
• Less Breakable: No worries about breaking glass when transporting or storing.

3. Cans Are More Environmentally Friendly

• Easier to Recycle: Aluminum is more efficiently and widely recycled than glass.
• Lower Carbon Footprint: Because they are lighter and stackable, transporting cans requires less fuel than bottles.

4. Canned Beer Cools Down faster

• Chills Quicker: Aluminum conducts heat better than glass, so beer in a can cools down faster in a fridge or ice chest.

5. Cans Are More Versatile for Activities

• Allowed in More Places: Many beaches, parks, and events prohibit glass but allow cans.
• Better for Outdoor Adventures: Easier to pack out and crush when empty.

When Would a Brewer Choose to Make Bottled vs Canned Beer?

There are a few reasons why a brewery might choose bottled vs canned beer, some pragmatic, some cosmetic:

1. Tradition & Brand Perception

• Craft & Premium Image: Bottled beer is often associated with higher-end, traditional, or specialty brews, as many classic European and craft breweries have historically used bottles.
• Consumer Expectation: Some consumers associate bottled beer with better quality, especially for styles like Belgian ales, stouts, and barrel-aged beers.

2. Cost & Equipment Investment

• Lower Initial Investment: Bottling equipment is generally less expensive than canning equipment, making it more accessible to smaller breweries.
• Easier Transition for Small Breweries: Many microbreweries start with bottling because they can manually cap bottles without needing large-scale canning lines.

3. Aging & Carbonation Control

• Better for Bottle Conditioning: Some beers (like Belgian ales, some IPAs, and farmhouse ales) undergo secondary fermentation in the bottle, which is harder to achieve in a can.
• Less Risk of Over-carbonation Issues: Bottles can withstand higher pressure variations than cans, which is useful for certain highly carbonated styles.

4. Consumer Experience

• Preference for Glass Drinking: Some drinkers prefer sipping directly from a bottle rather than a can, feeling it provides a better taste experience.
• Presentation & Labeling Options: Bottles allow for intricate labels, embossing, and unique shapes that help a brand stand out on shelves.
• Cork & Cage Presentation: Some premium beers use cork-and-cage closures for an elevated look and aging benefits, which isn’t possible with cans.

What Does Science Say About Canned Beer vs Bottled Beer?

Kathryn Fromuth and Jacquelin Chaparro, researchers from Colorado State University, put the question to the test. They took IPA and amber ale from New Belgium Brewing Company and placed them in brown bottles and aluminum cans. They copied storage conditions these drinks would go through and then tested the results at different intervals over the course of six months. What they found wasn’t as clear as you might expect. 

They found that the beer’s flavor and longevity depend on what type of beer is being stored. The amber ale showed that the fruity flavor and aroma lasted longer in the bottle than in the can (most likely due to the sealing process of the can.) And the IPA lasted longer in the can. So the answer to the question “Which one is best, canned or bottled beer?” depends on the type of beer getting stored.

Are There Really Any Taste Differences Between Canned Beer vs Bottled?

There’s a common misconception that beer from a can tastes metallic. However, modern can liners prevent any direct contact between the beer and aluminum to protect the flavor. 

If you need a final answer in the bottled beer vs canned beer debate, we have one: it’s neither. Pour it in a glass and don’t worry about it.
