Fermenting Away

OK, the sauerkraut is finally finished and on its way. I got delayed by a day but was out early this morning and collected about 25 pounds of cabbage. All shredded and salted and muddled and in the crock. All that cabbage and it only filled the crock about a third of the way (It's marked 10 gallon) after the muddling and salting. The crock has been in the family for who knows how long and my mother passed it to me. How much kraut and how many pickles has it made? BTW 25 pounds of cabbage is a lot of cabbage to shred. We should have sauerkraut by August.
