The Maya Popol Vuh describes human beings as literally made of corn.<\/p>\n<p>The fermentation process that produced chicha was radically different from European malting: the grain was chewed to release salivary amylases, enzymes capable of converting starches into fermentable sugars. The resulting mixture was left to ferment spontaneously in clay vessels.<\/p>\n<p>A study published in <em>Frontiers in Microbiology<\/em> (2020) confirmed that traditional Peruvian chicha contains a complex microbial ecosystem of wild yeasts and lactic bacteria comparable to modern spontaneous fermentations.<\/p>\n<p>In Mexico, the Rar\u00e1muri (Tarahumaras) of the Sierra Madre developed tesg\u00fcino, a fermented corn beer that remains central to their community rituals.<\/p>\n<p>Unlike Andean jora chicha, which uses germinated corn in a process close to malting, tesg\u00fcino is made with nixtamalized corn \u2014 a process that would reappear, centuries later, in the craft breweries of the 21st century.<\/p>\n<h2>The problem of American barley<\/h2>\n<p>When German immigrants arrived en masse in the United States in the mid-19th century and tried to replicate the Bavarian lagers they knew, they encountered an unexpected obstacle.<\/p>\n<p>American six-row barley had a much higher protein content than European two-row barley. The result was cloudy, unstable beers prone to spoilage \u2014 incompatible with the clear, golden lager that had conquered Bavaria.<\/p>\n<p>The solution came from science, not tradition. Anton Schwarz, one of the most influential brewing scientists of the 19th century, published a series of articles in <em>The American Brewer<\/em> during the 1870s promoting the use of corn grits as an adjunct.<\/p>\n<p>The logic was impeccable: corn contains none of the proteins that generate haze, it is highly fermentable, and it was abundantly available in the Midwest at low cost.<\/p>\n<p>By the 1870s, Pabst Brewing Company and other Midwest breweries were already incorporating corn grits at around 20% of their grain bill to dilute the protein load of American barley and obtain a cleaner, more stable beer.<\/p>\n<p>On how the mashing process interacts with different starch sources: <a href=\"https:\/\/www.thebeertimes.com\/en\/single-infusion-vs-step-mashing-what-is-their-impact-on-the-final-beer\/\" target=\"_blank\" rel=\"noopener\">Simple infusion vs. step mashing<\/a>.<\/p>\n<h2>The year corn defeated Europe<\/h2>\n<p>The symbolic moment of legitimization for corn in brewing arrived in 1878, when Anheuser-Busch presented its corn lager at a competition in France and won the grand prize, surpassing European rivals brewing under the strict Reinheitsgebot.<\/p>\n<p>The irony was perfect. The &#8220;inferior&#8221; adjunct had produced a beer that Old World palates judged superior.<\/p>\n<p>That victory was not just commercial. It established an American brewing aesthetic: pale, clear, effervescent, light-bodied, conceived for mass consumption and hot summers \u2014 an aesthetic that would dominate global consumption for more than a century.<\/p>\n<h2>Building the modern brewing world<\/h2>\n<p>Prohibition (1920\u20131933) did not kill adjunct lagers; it perfected them. When breweries reopened, they competed for consumers who had gone thirteen years without legal beer.<\/p>\n<p>Light, accessible, affordable \u2014 the adjunct lager formula, refined during Prohibition and consolidated in its aftermath, fixed the global model.<\/p>\n<p>Corn can represent up to 20% of the grain bill in mainstream North American beers. Miller Lite, one of the most consumed beers in the world, uses corn as its primary adjunct.<\/p>\n<p>Anheuser-Busch&#8217;s Budweiser, by contrast, uses rice \u2014 a different adjunct with similar but not identical sensory objectives. By the late 20th century, adjunct lagers represented the majority of global beer volume.<\/p>\n<div id=\"thebe-3185146286\" style=\"margin-bottom: 20px;margin-left: auto;margin-right: auto;text-align: center;\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-9395258998211551\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block; text-align:center;\" data-ad-client=\"ca-pub-9395258998211551\" \ndata-ad-slot=\"1179889612\" \ndata-ad-layout=\"in-article\"\ndata-ad-format=\"fluid\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div>\n<h2>The craft movement condemns corn under an imported purity dogma<\/h2>\n<p>The American craft movement, which took root in the 1970s and exploded in the 1990s, defined itself partly in opposition to the adjunct lager.

Corn went from being a technological savior of the American brewing industry to the symbol of everything the craft movement despised.<\/p>\n<p>The great irony of this prejudice is that it ignores the technical reality that forced industrial breweries to use corn in the first place. The large companies did not start using adjuncts out of sheer greed.<\/p>\n<p>They did so out of an inescapable agronomic necessity \u2014 American six-row Midwest barley had excess proteins that created haze and instability. Corn solved that chemical problem brilliantly and scientifically.<\/p>\n<p>The result was a paradox and a profound historical amnesia. The movement that proclaimed itself the defender of beer history and tradition ended up demonizing the oldest and most native fermented ingredient on the continent.<\/p>\n<p>It would take decades and the arrival of the terroir obsession for new generations of brewers to realize they were rejecting their own agricultural history.<\/p>\n<h2>The vindication of corn as an ingredient<\/h2>\n<p>Corn&#8217;s rehabilitation as a craft ingredient did not arrive as a manifesto. It arrived as experimentation.<\/p>\n<p>The first vector was historical \u2014 the rediscovery of Cream Ale as a genuinely American style. Cream Ale, a pre-Prohibition style that typically incorporated 20\u201330% corn, was not an industrial product; it was the American answer to the German lager, brewed with local ingredients. Brewers who took it seriously had to take corn seriously with it.<\/p>\n<p>The second vector was geographic: the explosion of craft Mexican lagers. Seeking authentic versions of the styles popular among Latin American communities, brewers discovered that nixtamalized corn was the key to the flavor profile they were after.<\/p>\n<p>Dangerous Man Brewing (Minneapolis) partnered with Nixta Tortiller\u00eda to produce Heirloom Sipper, a lager made with five varieties of nixtamalized Mexican corn \u2014 yellow, pink, red, white, and blue \u2014 that foregrounded the complexity of the grain.<\/p>\n<p>Bierstadt Lagerhaus (Denver) used Bolita Belatove and Bolita Azul corn from Oaxaca in their Heirloom Corn Lager: varieties with flavor profiles impossible to replicate with standard industrial corn.<\/p>\n<p>A 2020 study published in <em>Food Research International<\/em> (<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC7404799\/\" target=\"_blank\" rel=\"noopener noreferrer\">PMC7404799<\/a>) on Mexican pigmented corn beers identified specific aromas \u2014 fermented fruits, tortilla, dried chile, bread \u2014 that only appear when varieties with their characteristic phenolic profiles are used.<\/p>\n<p>The conclusion was unambiguous: corn, like hops or malt, has a sensory complexity that depends on variety, origin, and process.<\/p>\n<h2>What really changes when corn is in the glass?<\/h2>\n<p>For a trained taster, the presence of corn in the grain bill leaves specific, identifiable signals:<\/p>\n<h3>1. Body and texture<\/h3>\n<p>Corn is highly fermentable: its starches convert almost entirely into fermentable sugars, with minimal residual dextrins. The result is a lighter, drier body than the 100% malt equivalent.<\/p>\n<p>The mouthfeel is thinner, perceived as more &#8220;refreshing&#8221; or as less complex, depending on context and the taster&#8217;s expectations.<\/p>\n<h3>2. Color<\/h3>\n<p>Corn contributes virtually no color. Incorporating it into the grain bill produces a paler beer than the all-malt equivalent. This is one of the reasons the American adjunct lager aesthetic evolved toward a very pale gold.<\/p>\n<h3>3. Foam<\/h3>\n<p>Here corn works against the brewer. As a low-protein adjunct, it does not contribute the compounds that favor foam formation and retention.<\/p>\n<p>Proportions above 25\u201330% noticeably reduce collar persistence, which partly explains why industrial adjunct lagers are served at very low temperatures.<\/p>\n<h3>4. Flavor profile<\/h3>\n<p>Standard industrial corn contributes a neutral character \u2014 its function is precisely to &#8220;not taste.&#8221; But nixtamalized corn or heirloom pigmented varieties introduce a gentle sweetness, a slightly oily character, and in colored varieties, phenolics that add complexity.<\/p>\n<p>The difference between a Mexican Lager made with Bolita Azul corn and one made with conventional dent corn is as perceptible to a trained taster as the difference between two distinct hop varieties.<\/p>\n<h3>5. Fermentability and attenuation<\/h3>\n<p>A grain bill with 20\u201325% corn will produce a measurably drier beer than the same all-malt bill, since corn adds fermentable sugars without contributing non-fermentable dextrins. For a brewer seeking precise control of final gravity, this is critical technical information.<\/p>\n<h2>Frequently Asked Questions (FAQ)<\/h2>\n<h3>1. Does corn need to be gelatinized before mashing?<\/h3>\n<p>Yes. Corn starch gelatinizes at higher temperatures than barley malt starch \u2014 between 62\u00b0C and 72\u00b0C depending on the variety. This means that if raw corn is added directly to the mash, the malt enzymes will not be able to access its starches. Industrial brewers solve this with a separate cereal cooker, while craft brewers using nixtamalized corn or pre-cooked corn flour take advantage of the fact that the prior alkaline or thermal process has already gelatinized the starch, simplifying the mash.<\/p>\n<h3>2. What is the technical difference between grits, corn flour, and nixtamalized corn?<\/h3>\n<p>Grits are degerminated, defatted corn semolina, designed to contribute fermentable sugars without flavor or fat that could go rancid. Conventional corn flour retains the germ and contributes more body but has lower stability. Nixtamalized corn, treated with lime or ash, modifies its chemical structure: it releases niacin, reduces phytates, and generates distinctive aromatic compounds evoking fresh tortilla. Each format requires different adjustments in the mash and produces radically different sensory profiles.<\/p>\n<h3>3. Does beer made with corn contain gluten and is it suitable for celiacs?<\/h3>\n<p>Not by default. Corn is naturally gluten-free, but in the vast majority of beers that use it, corn functions as an adjunct alongside barley or wheat malt, which do contain gluten. To obtain a truly gluten-free beer using corn, the brewer must work with a 100% corn grain bill or combine it exclusively with other gluten-free grains such as sorghum, rice, or millet, and use external enzymes to compensate for the absence of diastatic power from barley.<\/p>\n<h3>4. What is the maximum recommended corn percentage without compromising foam retention?<\/h3>\n<p>Most experienced brewers set the practical limit between 20% and 30% of the total grain bill. Below 20%, the impact on foam is minimal and barely perceptible to the average consumer. Between 20% and 30%, the reduction in collar persistence is noticeable but manageable with techniques such as mashing at lower temperatures to preserve malt base proteins, using small proportions of caramel malts, or adding natural foaming agents. Exceeding 30% requires significant technical compensation and is generally only justified in styles where extreme dryness and light body are the central objective.<\/p>\n<h3>5. Is Cream Ale an ale or a lager, and what role does corn play in its profile?<\/h3>\n<p>Cream Ale is technically an ale, fermented with Saccharomyces cerevisiae yeasts at typical ale temperatures (18\u201322\u00b0C). However, many brewers condition it at cold lager temperatures (close to 0\u00b0C) for weeks \u2014 a process called cold conditioning that produces a cleanliness and smoothness atypical for an ale. Corn plays a key structural role: by contributing highly fermentable sugars without proteins or dextrins, it produces an exceptionally light and dry body that defines the &#8220;smooth&#8221; (cream) character of the style. Without corn, the beer tends to feel denser and less refreshing, losing the identity that distinguishes it from an English bitter or an American pale ale.<\/p>\n<p>{<br \/>\n  &#8220;@context&#8221;: &#8220;https:\/\/schema.org&#8221;,<br \/>\n  &#8220;@type&#8221;: &#8220;FAQPage&#8221;,<br \/>\n  &#8220;mainEntity&#8221;: [<br \/>\n    {<br \/>\n      &#8220;@type&#8221;: &#8220;Question&#8221;,<br \/>\n      &#8220;name&#8221;: &#8220;Does corn need to be gelatinized before mashing?&#8221;,<br \/>\n      &#8220;acceptedAnswer&#8221;: {<br \/>\n        &#8220;@type&#8221;: &#8220;Answer&#8221;,<br \/>\n        &#8220;text&#8221;: &#8220;Yes.

To obtain a truly gluten-free beer using corn, the brewer must work with a 100% corn grain bill or combine it exclusively with other gluten-free grains such as sorghum, rice, or millet, and use external enzymes to compensate for the absence of diastatic power from barley.&#8221;<br \/>\n      }<br \/>\n    },<br \/>\n    {<br \/>\n      &#8220;@type&#8221;: &#8220;Question&#8221;,<br \/>\n      &#8220;name&#8221;: &#8220;What is the maximum recommended corn percentage without compromising foam retention?&#8221;,<br \/>\n      &#8220;acceptedAnswer&#8221;: {<br \/>\n        &#8220;@type&#8221;: &#8220;Answer&#8221;,<br \/>\n        &#8220;text&#8221;: &#8220;Most experienced brewers set the practical limit between 20% and 30% of the total grain bill. Below 20%, the impact on foam is minimal and barely perceptible to the average consumer. Between 20% and 30%, the reduction in collar persistence is noticeable but manageable with techniques such as mashing at lower temperatures to preserve malt base proteins, using small proportions of caramel malts, or adding natural foaming agents. Exceeding 30% requires significant technical compensation and is generally only justified in styles where extreme dryness and light body are the central objective.&#8221;<br \/>\n      }<br \/>\n    },<br \/>\n    {<br \/>\n      &#8220;@type&#8221;: &#8220;Question&#8221;,<br \/>\n      &#8220;name&#8221;: &#8220;Is Cream Ale an ale or a lager, and what role does corn play in its profile?&#8221;,<br \/>\n      &#8220;acceptedAnswer&#8221;: {<br \/>\n        &#8220;@type&#8221;: &#8220;Answer&#8221;,<br \/>\n        &#8220;text&#8221;: &#8220;Cream Ale is technically an ale, fermented with Saccharomyces cerevisiae yeasts at typical ale temperatures (18-22\u00b0C). However, many brewers condition it at cold lager temperatures (close to 0\u00b0C) for weeks \u2014 a process called cold conditioning that produces a cleanliness and smoothness atypical for an ale. Corn plays a key structural role: by contributing highly fermentable sugars without proteins or dextrins, it produces an exceptionally light and dry body that defines the smooth (cream) character of the style. Without corn, the beer tends to feel denser and less refreshing, losing the identity that distinguishes it from an English bitter or an American pale ale.&#8221;<br \/>\n      }<br \/>\n    }<br \/>\n  ]<br \/>\n}<\/p>\n<h2>Recommended<\/h2><div id=\"thebe-4193836825\" class=\"thebe-adsterra-300-x-250 thebe-entity-placement\" style=\"margin-top: 15px;margin-left: auto;margin-right: auto;text-align: center;\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-9395258998211551\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-9395258998211551\" \ndata-ad-slot=\"1930811761\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div>\n<ul>\n<li><a href=\"https:\/\/www.thebeertimes.com\/en\/the-battle-for-the-survival-of-pulque-the-elixir-of-the-ancient-mexicans\/\" target=\"_blank\" rel=\"noopener\">The battle for the survival of pulque, the elixir of the ancient Mexicans<\/a><\/li>\n<li><a href=\"https:\/\/www.thebeertimes.com\/en\/single-infusion-vs-step-mashing-what-is-their-impact-on-the-final-beer\/\" target=\"_blank\" rel=\"noopener\">Simple infusion vs. step mashing: impact on the final beer<\/a><\/li>\n<\/ul>\n<div id=\"thebe-3481599925\" class=\"thebe-adskeeper-fin-articulo thebe-entity-placement\" style=\"margin-top: 20px;margin-left: auto;margin-right: auto;text-align: center;\"><div data-type=\"_mgwidget\" data-widget-id=\"1705281\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script><\/div>","protected":false},"excerpt":{"rendered":"<p>Corn was being fermented in America thousands of years before European barley arrived; later condemned by the American craft movement under an imported purity dogma, today it reclaims its place as a terroir ingredient.<\/p>\n","protected":false},"author":1,"featured_media":41639,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"wpai_generated_summary":"","footnotes":""},"categories":[21153],"tags":[21796,21480,21134,21222,21275],"class_list":["post-47244","post","type-post","status-publish","format-standard","has-post-thumbnail","category-history","tag-corn","tag-craft-beer","tag-history","tag-ingredients","tag-mexico-en"],"_links":{"self":[{"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/posts\/47244","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/comments?post=47244"}],"version-history":[{"count":1,"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/posts\/47244\/revisions"}],"predecessor-version":[{"id":47246,"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/posts\/47244\/revisions\/47246"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/media\/41639"}],"wp:attachment":[{"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/media?parent=47244"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/categories?post=47244"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.thebeertimes.com\/en\/wp-json\/wp\/v2\/tags?post=47244"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
