I enjoy sauerkraut too, and buy mine from the supermarkets here. Eat a bit too much and it does cause problems with the 'inards' though.It all seems very green round your way.
Love sauerkraut, You can buy it in tins over here, the Alsacians eat it with all sorts of meats, sausages, charcuterie and washed down with white wine. Yum Yum!!
They call it Choucroute Garnie.
