Lemon -do is the company's first sting on hard seltzer, and it can be the only product of its kind at any time. Garduño said since the drink was created for a "specific slice" of the Coca-Cola market, it will probably remain a Japanese exclusive.
"I don't think people all over the world should expect to see this kind of thing from Coca-Cola," he said.
"I think the culture here is still very unique and special, so many products born here will stay here."
In contrast to the Japanese spiked seltzer, the coffee convection actually contains coke and a heavy dose of caffeine. It's not guaranteed, but Javier Meza, the company's global marketing manager for sparkling drinks, said it could see a US debut as soon as 2020.
