Apart from trading in spices and colonial goods in his shop, "Haus der drei Lerchen / Dům U Tří skřivanů" ("House of the Three Woodlarks"),[3] he also produced alcoholic beverages.

In 1805 Prince Maxmillian Friedrich von Plettenberg arrived in Carlsbad for medical treatment, accompanied by his personal physician, Christian Frobrig from England.

Becher tested this recipe for two years, after which he began selling this new "English Bitter" liqueur, which was intended for the treatment of diseases of the stomach.

During the First World War, his Karlsbader Becherbitter was sold in Bohemia, Austria, Germany, Poland, Spain, Italy, Turkey and Egypt.

After the Second World War, Karlsbader Becherbitter became known as Becherovka following the dispossession and forceful expulsion of the German population of Karlovy Vary by the Czech state (see Beneš decrees).

[4] The Czech producer says that only two people know the secret of the entire production process and are allowed to enter the Drogikamr room – where, once a week, they mix the herbs and spices used in the drink.
