1838, the first bottles of Lea & Perrins Worcestershire sauce were released to the general public. Worcestershire sauce has been a generic term since 1876, when the English High Court of Justice ruled that Lea & Perrins did not own a trademark for the name Worcestershire. Ingredients The original ingredients in a bottle of Worcestershire sauce were: Barley malt vinegar Spirit vinegar Molasses Sugar Salt Anchovies Tamarind extract Shallots (later replaced by onions) Garlic Spices Flavourings Since many Worcestershire sauces include anchovies, it is avoided by those who are allergic to fish, and others who avoid eating fish, such as vegetarians. The Codex Alimentarius recommends that prepared food containing Worcestershire sauce with anchovies include a label warning of fish content, although this is not required in most jurisdictions. The US Department of Agriculture has required the recall of some products with undeclared Worcestershire sauce. Several brands sell anchovy-free varieties of Worcestershire sauce, often labelled as vegetarian or vegan. Generally, Orthodox Jews refrain from eating fish and meat in the same dish, so they do not use traditional Worcestershire sauce to season meat. However, certain brands are certified to contain less than 1/60 of the fish product and can be used with meat. Although soy sauce is used in many variations of the Worcestershire sauce since the 1880s, it is debated whether Lea & Perrins has ever used soy in their preparation. According to William Shurtleff's SoyInfo Center, a 1991 letter from factory general manager J. W. Garnett describes the brand switching to hydrolyzed vegetable protein during World War II due to shortages. As of 2021, soy is not declared as an ingredient in the Lea & Perrins sauce. Varieties Lea & Perrins The Lea & Perrins brand was commercialised in 1837 and continues to be the leading global brand of Worcestershire sauce. On 16 October 1897, Lea & Perrins relocated manufacturing of the sauce from their pharmacy in Broad Street to a factory in the city of Worcester on Midland Road, where it is still made. The factory produces ready-mixed bottles for domestic distribution and a concentrate for bottling abroad. In 1930, the Lea & Perrins operation was purchased by HP Foods, which was in turn acquired by the Imperial Tobacco Company in 1967. HP was sold to Danone in 1988 and then to Heinz in 2005.
