Demand for Bud Light has "plummeted" since the brand became embroiled in controversy over a promo with transgender influencer Dylan Mulvaney, according to the founder of a mobile bartending company. 

"There has been a ‘significant shift’ in consumer preferences," Catarina Tucker, the founder of Barnastics, told Fox News Digital. "Bud Light, once a popular option, is no longer capturing the attention or enthusiasm of event organizers and attendees."

Since the promo was first released in April, the brand has faced harsh backlash from consumers, some stores have been forced to give away the beer for free, and Bud Light has bought back expired beers from wholesalers, according to the Wall Street Journal.

Tucker said the liquor stores she works with have yet to sell Bud Light at a discount, but she has seen the backlash in real time. 

Barnastics allows customers to build a custom proposal, which allows the company to see when demand for products shifts. 

"[Demand for Bud Light] has plummeted completely. No one wants it at their event anymore," Tucker said. "There are a couple clients that have expressed to me their feelings behind it, and it’s no longer popular."

Tucker said consumers are becoming increasingly aware of whether the brands they support align with their values, and as a result, "are actively seeking alternatives to Bud Light, gravitating towards craft beers, specialty cocktails, and premium spirits."

Tucker said she does not foresee popularity of the beer picking up any time soon.   

"With the feedback that I’ve gotten and how strongly a lot of clients feel about it, it [the company] doesn’t switch gears, I don’t see the popularity picking back up," she said.

"Sometimes things blow over" she added, but recognized that Bud Light’s actions "hold a lot of weight" with their consumers.

But, Tucker said she has not seen the same plummeting demand for Budweiser, or other Anheuser-Busch products. "Anything Bud Light, they just won’t support," she added.
