Bayside Distributing was founded in 1948. Its first location was in an old mill building on the tidal portion of the Lamprey River in Newmarket. At the time there were at least six companies distributing beer in the seacoast, none with any large market share. Many of Bayside’s brands from 1948 no longer exist. The building was old, and inefficient, with low ceilings and uneven wooden floors. In many places the river was visible thru the floor. Cases were unloaded from tractor trailers one at a time.
