Since 200AD Maltsters have used floor maltings, a traditional method for malting barley. After the malt had been steeped it was laid out on the floors to germinate over the course of approximately 5 days. During the germination period, traditionally the malt had to be turned by hand every 8 hours, a skilled task using the shovel to turn the ‘couch’ to prevent the roots from matting. Turning the germinating grain maintained optimal conditions, ensuring even temperature and moisture.
