Ale.<\/p>\n<p>Until then, canned beer had been associated with industrial beer, and bottled beer with quality craft beer.<\/p>\n<p>This began a debate that still has several dimensions today.<\/p>\n<h2>1. Beer Conservation<\/h2>\n<p>There are three decisive factors when it comes to preserving a beer: oxygen, light, and temperature.<\/p>\n<p><span style=\"font-size: 19px;\">Green, blue, or clear bottles <\/span>let too much light through, causing degradation in the hop compounds that develops the same components responsible for the unpleasant smell of skunk spray.<\/p>\n<p>In practice, <a href=\"https:\/\/www.thebeertimes.com\/en\/the-photochemical-degradation-of-beer-and-the-origin-of-the-skunky-odor\/\" target=\"_blank\" rel=\"noopener\">only amber-colored bottles<\/a> manage to block up to 85% of the ultraviolet wavelengths.<\/p>\n<figure id=\"attachment_5463\" aria-describedby=\"caption-attachment-5463\" style=\"width: 603px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5463 size-full\" title=\"Photochemical degradation of beer\" src=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2016\/09\/cerveza_zorrillo.jpg\" alt=\"Photochemical degradation of beer\" width=\"603\" height=\"216\" srcset=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2016\/09\/cerveza_zorrillo.jpg 603w, https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2016\/09\/cerveza_zorrillo-300x107.jpg 300w\" sizes=\"auto, (max-width: 603px) 100vw, 603px\" \/><figcaption id=\"caption-attachment-5463\" class=\"wp-caption-text\">Photochemical degradation of beer<\/figcaption><\/figure>\n<p><span style=\"font-size: 19px;\">For their part, cans are completely opaque, as aluminum<\/span><span style=\"font-size: 19px;\"> completely blocks light from entering the interior.<\/span><\/p>\n<p>As for oxygen, there is always a space at the neck of a bottle that can store or filter air through the edges of the cap, <a href=\"https:\/\/www.thebeertimes.com\/en\/causes-and-effects-of-oxidation-in-beer-everything-you-need-to-know\/\" target=\"_blank\" rel=\"noopener\">oxidizing the beer<\/a>. Cans, for their part, are completely airtight.<\/p>\n<p>Regarding temperature, a can heats and cools more quickly than a bottle, which can be positive or negative depending on how you manage it.<\/p>\n<p>As for flavor, something that concerns many consumers is that beer might taste metallic, since in the past the liquid was in direct contact with aluminum, but this is no longer the case today.<\/p>\n<p>Currently, cans are coated internally with a water-based polymer film that completely isolates the liquid inside.<\/p>\n<h3>Conclusion<\/h3>\n<p>Cans preserve beer better, especially highly hopped styles that should ideally be consumed shortly after being brewed.<\/p>\n<h2>2. Beer Transport<\/h2>\n<p>The arguments here are easier to calculate, but first let&#8217;s look at the numbers: a 330 ml can weighs about 370 grams and a 330 ml bottle weighs about 565 grams.<\/p>\n<figure id=\"attachment_5614\" aria-describedby=\"caption-attachment-5614\" style=\"width: 472px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5614 size-full\" title=\"Transport of bottles vs. cans\" src=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2017\/07\/Transporte_Cerveza_Botella_Lata.jpg\" alt=\"Beer transport\" width=\"472\" height=\"309\" srcset=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2017\/07\/Transporte_Cerveza_Botella_Lata.jpg 472w, https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2017\/07\/Transporte_Cerveza_Botella_Lata-300x196.jpg 300w\" sizes=\"auto, (max-width: 472px) 100vw, 472px\" \/><figcaption id=\"caption-attachment-5614\" class=\"wp-caption-text\">Transport of bottles vs. cans<\/figcaption><\/figure>\n<p>It does not seem like a big difference at first glance, but when we think about a six-pack, a case of 24 beers, or a fully loaded delivery truck, the difference is significant, with cans also making far more efficient use of space than bottles.<\/p>\n<h3>Conclusion<\/h3>\n<p>Cans win by a landslide.<\/p><div id=\"thebe-1279765582\" class=\"thebe-libros-amazon thebe-entity-placement\" style=\"margin-left: auto;margin-right: auto;text-align: center;\"><div style=\"background-color: #ffffff; border: 1px solid #ccc; border-radius: 12px; padding: 16px; max-width: 320px; margin: 20px auto; text-align: center; font-family: helvetica, arial, sans-serif;\">\n<p><a href=\"https:\/\/amzn.to\/3LddZmQ\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-43340 aligncenter\" src=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/05\/Catar-cerveza-300x300.jpg\" alt=\"Gu\u00eda Pr\u00e1ctica Catar Cerveza Amazon\" width=\"200\" height=\"199\" srcset=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/05\/Catar-cerveza-300x300.jpg 300w, https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/05\/Catar-cerveza-150x150.jpg 150w, https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/05\/Catar-cerveza-370x370.jpg 370w, https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/05\/Catar-cerveza.jpg 500w\" sizes=\"auto, (max-width: 200px) 100vw, 200px\" \/><\/a><\/p>\n<p style=\"color: #0000ff; font-weight: bold; margin: 8px 0; line-height: 1.2;\"><a href=\"https:\/\/amzn.to\/3LddZmQ\" target=\"_blank\" rel=\"nofollow\"><span style=\"font-size: 11pt;\">Gu\u00eda pr\u00e1ctica para catar cerveza: C\u00f3mo apreciar correctamente todas las cervezas del mundo<\/span><\/a><\/p>\n<p><a class=\"fasc-button fasc-size-medium fasc-type-flat fasc-rounded-medium fasc-ico-before dashicons-cart\" style=\"background-color: #ff9900; color: #000000;\" target=\"_blank\" rel=\"nofollow\" href=\"https:\/\/amzn.to\/3LddZmQ\">Comprar en Amazon<\/a><\/p>\n<\/div>\n<\/div>\n<h2>3.

They work better for the light and aromatic styles that most customers prefer today.<\/p>\n<p>In the long run, they could also lower transport and storage costs, making the industry more viable and giving consumers better prices.<\/p>\n<p>For cellared beers and special malt-forward brews, the bottle may have a slight advantage, with a factor of romance and presence that is hard to beat.<\/p>\n<h2>Frequently Asked Questions (FAQ)<\/h2>\n<h3>1. Is it better to drink craft beer directly from the can or from a glass?<\/h3>\n<p>Always from a glass. The can is designed to preserve beer, not to drink from. Pouring the beer into a clean glass allows you to appreciate the color, release the volatile aromas, and generate the right head. Direct contact of the lips with aluminum can add a metallic sensation that, while it does not alter the flavor of the liquid itself, does affect the drinker&#8217;s sensory perception.<\/p>\n<h3>2. How much longer does craft beer last in a can than in a bottle?<\/h3>\n<p>Under equal conditions, cans extend the shelf life of highly hopped styles by 30 to 60 days more than amber glass bottles. The can eliminates two of the three deterioration factors: light and oxygen. Amber bottles block up to 85% of UV wavelengths but are not completely airtight, while cans are opaque and seal without an air gap at the neck.<\/p>\n<h3>3. Why are some craft beer styles never packaged in cans?<\/h3>\n<p>Styles that require secondary fermentation inside the container are not compatible with cans. Traditional Belgian beers such as Trappist, Gueuze, or Lambic ferment inside the bottle with the addition of sugars, generating natural carbonation and live sediment. This process would cause a can to explode. The same applies to long-term barrel-aged beers, where the corked glass bottle is part of the maturation process.<\/p>\n<h3>4. Does craft beer in a can really taste metallic?<\/h3>\n<p>No, if the can is in good condition. Since the 1990s, all aluminum cans have been manufactured with a water-based polymer interior coating that completely isolates the liquid from the metal. The metallic taste some consumers report is usually due to drinking directly from the can, damaged cans, or containers stored at extreme temperatures.<\/p>\n<h3>5. How does refrigeration affect the flavor of craft beer depending on the format?<\/h3>\n<p>The can responds faster to temperature changes: it cools down sooner in the fridge but also warms up faster outside of it. For immediate consumption, the can is more practical. The bottle, having greater glass mass, maintains a stable temperature for longer once served. For cellared beers that require cold maturation, the bottle offers greater thermal stability over the long term.<\/p><div id=\"thebe-2507548652\" class=\"thebe-membresia thebe-entity-placement\" style=\"margin-bottom: 15px;margin-left: auto;margin-right: auto;text-align: center;\"><a href=\"https:\/\/www.thebeertimes.com\/es\/niveles-de-membresia\/\" target=\"_blank\" aria-label=\"Navegar sin publicidad\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/10\/Navegar-sin-publicidad.png\" alt=\"\"  srcset=\"https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/10\/Navegar-sin-publicidad.png 590w, https:\/\/www.thebeertimes.com\/wp-content\/uploads\/2025\/10\/Navegar-sin-publicidad-300x184.png 300w\" sizes=\"(max-width: 590px) 100vw, 590px\" width=\"400\" height=\"245\"  style=\"display: inline-block;\" \/><\/a><\/div>\n<p><script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Is it better to drink craft beer directly from the can or from a glass?\",\n      \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Always from a glass.
