Todd Bellomy, of the Sam Adams Brewery in Boston, Mass., said that fire and weather have also affected hop yields in recent years. In 2006, a hop warehouse in Yakima Washington caught fire and as much as 2 percent of the world hop supply was lost, he said.
Other hop growers have struggled with flooding and drought, which further strained depleted hop stores, Bellomy said.
Hops are a small, vine-grown plant used in brewing beer. The crop is grown world-wide and in varying climates. Hops are grown largely on the West Coast in the United States. The crop is harvested in late summer and processed for use in brewing.

Sam Adams, owned by the Boston Beer Company, initiated a hop sharing program last year, allowing smaller breweries to buy hops at a set price. Boston Beer Company imports its hops from Germany and England at fixed prices.
Bellomy said it would be tough telling whether the market will stabilize this year. “We won’t know until October or November,” after the crop is harvested and processed, he said.
Olsen predicts that the market will stabilize in one or two years. “There are more acres going in,” he said. Brewers will not see an immediate increase though, as it takes a few years for hop crops to mature, he said.
“Prices will go down [eventually], but not to where they used to be,” Olsen said.
Craft brewers will also have to adjust to the type of hops farmers are planting, he added.
“International buyers want high-alpha hops, and craft brewers use aroma hops,” Olsen said.
High-alpha hops allow brewers to use less hops in their recipes, while craft brewers tend to use larger amounts of aroma hops in their recipes. But, “there’s no real difference between aroma and alpha,” and brewers will adjust to survive, he said.
