Beer, malt beverage and cider sales volumes fell 6.3 percent in the four weeks ending May 2, according to Nielsen data.
The decline is primarily attributed to surging gas prices, which are forcing American consumers to reduce discretionary spending on impulse purchases.
Convenience stores and gas stations experienced the steepest drops in sales, with volumes down about 9 percent year over year.
California saw the largest decrease in beer sales nationwide at 16 percent, correlating with its persistently high gas prices, while Arizona and Texas also reported significant declines.
The overall drop in alcohol consumption is also influenced by younger generations drinking less due to health concerns, contributing to a record-low national drinking rate.
