Corn
I have some flour which was ground there yesterday, unfortunately because of health and safety laws they cant grind and sell the flour produced.
One of the two waterwheels is in working order and was turning yesterday. The miller explained many things to me. The gearing on the mill is in two parts, a lower part which looks like its cast from iron. The upper parts are made from wood. Each wooden tooth is made to be replaced easily so that if there is a catastrophic failure the wooden teeth sheare off and can be replaced easily and fairly quickly in a matter of hours, this negates the issues that would arise if the Iron gearing were to shatter, this might take a good deal longer to repair. Incidently the wooden teeth are I was told made from wood of fruit trees, this being a naturally self lubricating kind of wood, this means that no grease could therefore come into contact with the flour.
There is still a steam engine on the site, but while I took pictures of it, my attention was drawn to the mill wheels and the stones grinding corn. The water supply to the mill isnt great so it doesnt run at what would have been its full operating speed, but it is magic to be in there when that wheel is turning, the mill does have a life of it's own.
The miller said that there have been suggestions that at some point in the future they might dredge the water course that supplies the water and try to restore a better flow, I can only imagine what it must feel like to be in there if the mill was going at full pelt.
