For the first time in three decades, Californians have reduced their annual consumption in all three categories of alcoholic beverages - beer, wine and hard liquor, researchers reported Wednesday.

Statistics compiled by the California Board of Equalization showed that per capita consumption of beer in the 1987-88 fiscal year declined by 4.4 percent. Use of wine decreased by 3.8 percent and of liquor by 4.9 percent."For the last 30 years, for most of that period, they were all up in per capita consumption," said board researcher Mark Lauchli. "Then distilled spirits started to drop, then wine and now beer."

However, Lauchli said, despite the declines, Californians on the average still are drinking almost 60 percent more beer than they did 30 years ago, twice as much wine and slightly more liquor.
