The next line for The Most Interesting Man in the World may come from a fan with a phone, not a copywriter with a brief. Dos Equis is asking consumers to help write the next national ad for one of beer advertising’s best-known characters, a move that comes as beer brands fight harder for attention in a softer U.S. market. The Heineken-owned Mexican beer brand is inviting fans to submit original “legend lines,” with three winning entries set to appear in a national TV commercial airing during College Football season.

The idea builds on a behavior Heineken says fans were already doing on their own. “One of the most memorable parts of The Most Interesting Man campaign has always been the legend lines featured on the TV commercials, and for years we've seen fans contribute to the iconicity of this campaign by writing their own lines on social and beyond,” said Alison Payne, Chief Marketing Officer at Heineken USA, in the announcement.

Fans can enter by commenting on official social posts, including the brand’s Instagram contest post. One winner will be selected each month from May through July. The selected comments will become part of the brand’s next national TV campaign. The College Football timing gives the contest a visible endpoint, moving the winning lines from social comments into a national media setting. Prizes include VIP access to Fuerza Regida’s “This Is Our Dream” stadium tour, a specialty dining experience curated by Phil Rosenthal and a college football game arrival with The Most Interesting Man.

The campaign is a social contest on the surface. However the larger business question is if a familiar advertising figure can help Dos Equis remain relevant at a time when beer brands are competing harder for fewer casual drinking occasions.

A Softer Beer Market Raises The Stakes

The U.S. beer market is not in an easy-growth period. Overall U.S. beer production and imports declined 5.7 percent in 2025, according to the Brewers Association. Craft brewer volume sales fell 4 percent, while craft retail dollar sales declined 3.6 percent to $27.8 billion. Craft still represented 13.3 percent of U.S. beer market volume and 24.6 percent of the $113 billion U.S. beer market by retail dollars, but the broader category signal is clear. Beer brands need to work harder to earn attention.

The pressure is not limited to beer brands competing with one another. Beer is also competing for occasions against spirits, ready-to-drink cocktails, hard seltzers and nonalcoholic beverages. This makes cultural visibility more important, particularly for brands that depend on social settings, sports viewing and group occasions.

This is an ongoing opportunity for Dos Equis because imported beer remains a meaningful part of the U.S. category. The Beer Institute says imported beer accounts for nearly 18 percent of all beer consumed in the United States. Mexican import beer remains one of the more visible segments of the import category, even as the broader beer market becomes more competitive. Imported beer has scale, but brands still need distinctiveness in a market where consumers have more beverage options.

Heineken also has a reason to keep investing behind the Mexican beer brand. In its 2025 full-year results, the company said Dos Equis, Tecate Original and Indio delivered steady low-single-digit volume growth within its Mexico portfolio.

Why Dos Equis Needs More Than Nostalgia

The Most Interesting Man in the World remains one of beer advertising’s most recognizable assets. Recognition alone, however, is not enough. A revived campaign can remind people of what they liked in the past, but it still has to give them a reason to care now.

The comment-driven approach is more useful than a simple return of the character. The brand is not only bringing back a familiar figure. It is asking fans to help write him as the character has always been built around language. The appeal came from short, dry, third-person lines that made ordinary advertising feel like comic folklore. The brand cites examples such as “he parallel-parked a train,” “when in Rome, they do as he does” and “he is the life of parties that he has never even attended.” The structure is easy to recognize and easy to imitate.

Dos Equis is not alone in trying to make a familiar beer brand feel current. Miller Lite has leaned into nostalgia around its 50th anniversary with “Legendary Stories Start With A Lite,” while Coors Light turned a spelling mistake into a limited “Mondays Light” campaign, showing how beer brands are using humor and history to stay visible in a crowded category.

The Comment Section Becomes The Creative Test

User-generated content often sounds better in a brand plan than it performs in the market. Much of it is hard to control. The Most Interesting Man campaign is not asking consumers to post general lifestyle content or explain why they like the beer. It is asking them to write within a specific creative structure.

A clear format gives fans a game to play. It also gives the brand a cleaner way to judge submissions. The best line can function as a social comment, a caption, a short-form video prompt or a TV voiceover. The entry itself can become usable campaign material.

Also the campaign also reflects how brands are treating the products and events as connected parts of the same content strategy. “Premium beverages set the tone and often become one of the most shared parts of the event on social media, helping reinforce the brand’s cultural relevance,” said Candace Youde, Cofounder of élever.

The Risk Is Whether Fans Can Match The Original Writing

The risk is that participation can become a gimmick if the final creative does not match the quality of the original campaign. The Most Interesting Man worked because the writing was precise. Opening the format to fans may generate engagement, but the brand will still need to curate carefully.

A weak winning line could make the campaign feel like a social stunt. A strong one could make the character feel current without changing what made him familiar. This is a balance they will have to manage. The brand needs fan involvement, but it cannot let the character become generic humor.

The Bottom Line For Dos Equis

Dos Equis is not trying to reinvent their original campaign. It is trying to make him participatory, which is a stronger strategy than simply reviving a familiar campaign.

Beer brands are facing a tougher market, and imported beer brands still need to earn attention even when the segment remains important. Dos Equis brand has a recognizable campaign asset, a repeatable writing format and a social audience that already understands the joke. The test for The Most Interesting Man in the World will be if fan-written lines can make a familiar character feel relevant again at a time when beer brands need more than recognition to win attention.
