 The Company's extensive connections in Europe enabled it to branch out into production of food-processing ingredients.In 1863, Erhart and Pfizer began importing crude argols — the tartar deposits formed in wine casks during the aging process—from France and Italy and set up their own refining operation for the manufacture of tartar and tartaric acid, which was used by bakers, beverage manufacturers, and in cooking.Sales began to climb, and by 1871, revenues of the young company were about $1.4 million.
