Süßmost – Volksgetränk! (“Sweet must – popular drink!”) is a “practical guide for making unfermented fruit and berry juices at home and in the family”, edited by Maria Kirschner and Alfons Baumgärtner and published by the Catholic Hoheneck-Verlag who dedicated several of its titles to the fight against alcoholism. In 1934, it was located in Berlin SW 48. Baumgärtner may or may not be identical with the clergyman of this name. The cover illustration is by Paula Fischer (signed as “PF”).
