Mineral Water

• The water used to make Becherovka always comes from Karlovy Vary, Becher's hometown and the Czech Republic's most famous spa destination. The high mineral content of Karlovy Vary water is said to have unique healing properties, particularly for digestive ailments.

Herbs and Spices

• Like most blends of herbs and spices used in popular products, the ingredients in Becherovka's mix are a well-guarded secret. According to the company's website, only two employees, the production manager and director of strategy and product development, are privy to the secret recipe. The company does reveal that the mystery herb-spice blend is macerated in a concentrated alcohol, which is then added to other ingredients to create the final product.

Other Ingredients

• The only other ingredients in Becherovka are alcohol and natural sugar. In addition to owning a shop, Josef Becher also made his own hard alcohol with a stillhouse he rented in town. Becherovka was developed using Becher's alcohol and a recipe of herbs and spices provided by an English physician, Dr. Frobrig. As for sugar, Becherovka contains real table sugar rather than artificial sweeteners to ensure a 100 percent natural product, according to the company's website.
