Ever hear the saying, "the demand is outpacing the production"? That's what's happening to White Claw's hard seltzers.

According to WIVB, there's a nationwide shortage of the popular drink.

White Claw suggests it became the victim of its own success, with demand taking off faster than expected.

Sales for the drinks have exploded -- climbing 300 percent in July compared to July of 2018.

White Claw says it's hard at work to increase its supplies. No word on when they will be able to properly keep up with demand.

Everyone seems to have one of these in their hands at parties these days, so it's not surprising.
