And the Mad Money host believes the rise of craft beer is a major trend that's sweeping not just the nation, but the entire globe.
According to the website run by the Brewer's Association, a craft beer is a beer made by a brewer who has either an all malt flagship or has at least 50% of its volume in either all malt beers or in beers which use adjuncts to enhance rather than lighten flavor.
"This is a real business—exports of craft beer soared 72% last year, and the markets in Canada, Brazil and Japan more than doubled.
And competition is growing at a rapid rate.
"Privately held Brooklyn Brewery, the company behind a craft beer called Brooklyn Lager, sold 176 thousand barrels of beer," Cramer said.
