Sourdough starter

Lately I've been making a lot of sourdough with the whey from our kefir during the cheese making process but I was fortunate enough to head down to Arroyo Grande to pick up some sourdough starter from a lady on Freecycle. She has a starter that is over 100 years old and it smells delicious. The poor thing is very set in its way so I'm trying to coax it to start on a different feeding cycle so that I can make bread more frequently than just once a week. I'll have to see how it goes as we start making bread with it on a more regular basis.
