NEW YORK – Coke (KO) and Pepsi (PEP) want to shake their Big Gulp image and cultivate a more hipster appeal.

The two soda giants are trying to rehabilitate soda’s cheap image and fetch higher prices as Americans keep cutting back on sugary fizz.

That means more stylized cans and bottles of Coke and the expansion of Mexican Coke, which is sweetened with sugar instead of high-fructose corn syrup. Pepsi is pushing “craft sodas” and even plans to open an eatery “honoring the kola nut” in New York City in the spring.

A press release for Pepsi’s Kola House last month was peppered with marketing buzzwords, and said the lounge would have a “resident cocktail curator” and “artisanal menu.” The idea is that its mere existence could burnish soda’s image, even if most people never go.

“At the end of the day, we just have to stay culturally relevant,” said Seth Kaufman, chief marketing officer for PepsiCo beverages in North America.

Soda remains a big business, with the familiar sizes like 12-ounce cans and 2-liter bottles still accounting for the vast majority of the market. But Americans are reaching for alternatives, with soda facing a proliferation of competitors and being blamed for fueling obesity. Between 2000 and 2014, U.S. soda volume fell 14 percent, according to industry tracker Beverage Digest.

If they’re selling less soda, Coke and Pepsi at least want to give it more cachet and charge more for it.

It’s why PepsiCo in 2014 introduced Caleb’s Kola, which comes in a glass bottle with the words “Honor in craft.” At a Beverage Digest conference in soon after, CEO Indra Nooyi said soda had lost some of its “cool factor” and that drinks like Caleb’s were helping bring it back.

That cool factor comes with a price. At a New York City grocery store, a 20-ounce bottle of Pepsi was selling for $1.49, compared with $1.99 for a 10-ounce bottle of Caleb’s.

PepsiCo also introduced Mountain Dew Dewshine that comes in a glass bottle and is made with sugar instead of high-fructose corn syrup, and displayed a soda called “1893” at a trade show. Like Caleb’s, 1893 is a reference to Pepsi’s creation by Caleb Bradham in 1893.

“It does address the coolness problem — or attempts to address the coolness problem,” said Ali Dibadj, a Bernstein analyst.

Dibadj said the focus on craft sodas is an attempt to emulate what happened in the beer industry, where craft beers have been the main driver of growth. But Dibadj thinks craft’s potential on soda may be more limited, since soda’s problem for most people isn’t taste, but the calories.

There is no definition for what makes a soda “craft,” but the trend is characterized by traits such as glass bottles and ingredients that are seen as more wholesome. Jaime Jose, a 21-year-old student from New York, doesn’t drink soda but said she’s tempted to buy the glass bottles of Coke as an occasional treat.

“It’s that retro thing of having a story behind it,” Jose said.

The idea is compelling enough that Coca-Cola created a “craft beverages team” last year that oversees recently acquired brands like Hansen’s.

It’s also presenting its flagship soda to fit craft sensibilities. Sandy Douglas, head of Coke North America, said last year that Coke’s packages by the end of the 1990s were all “huge” and “boring.”

But he said the newer aluminum bottles and mini-cans were winning back customers, particularly those with more earning power. He also said the smaller sizes were in line with the desire for more modest portions.

Coke Chief Financial Officer Kathy Waller said she thinks such alternative sizes could “easily go to 30 percent” of sales, up from about 15 percent last year.

Mexican Coke is also expanding distribution and enjoying double-digit volume growth, although it remains relatively minimal. The glass bottles and sugar that made it popular among certain circles are in step with the desire for “authentic” foods marketers say people increasingly want.
