Yeast and Fermentation / Increase in FG in secondary?

« on: December 19, 2012, 06:23:05 pm »

Is it possible to have final gravity increase in the secondary?  I brewed an alt with German Ale yeast and have a final gravity of 1.009 while in the primary.  After letting it sit in the secondary for 10 days, the final gravity was 1.015. Is this possible or did I likely misread my hydrometer after the primary?
