Lentia Enterprises offers authentic sourdoughs made in Germany by Ireks. Rye and wheat sours come as concentrated liquids and dry powders. Produced by the classic three-stage method, they use controlled strains of bacteria and a natural fermentation process. The degree of acidity varies from 100 to 200 for liquid forms and 40 to 170 for the dry styles. Some emphasize flavor while others heighten aroma.
