Lemon-do is the company's first stab at hard seltzer, and it may be the only product of its kind for some time. Garduño said since the drink was created for a "specific slice" of Coca-Cola's market, it will probably remain a Japanese exclusive.
"I do not think people around the world should expect this kind of thing from Coca-Cola," he said.
"I think the culture here is still very unique and special, so many products that are born here will stay here."
Unlike the Japanese spiked seltzer, the coffee concoction actually contains Coke and a hefty dose of caffeine. It is not guaranteed, but Javier Meza, the company's global leader in sparkling beverages, said that it could see a US debut as soon as 2020.
