Forgotten styles brewed according to their historic recipes by Dr. Fritz Briem, Munich, Germany. It was named after the Polish town of Grodzisk Wielkopolski or Grätz in German. Our historic version is brewed according to theGerman Purity Law with air-dried barley malt & beech smoked wheat malt and hopped with Perle & Saaz. A sour mash is created using the old and forgotten technique called “Digerieren”. Finally a three month aging & maturation process creates a complex sour, smoky & heavily hopped wheat ale.
