I do. I also "lagered" my BGSA in carboy. Brought the temp from upper 70's down to 31F by ramping down 4 degrees per day on my digital controller. I believe it sat at 31 for 3 weeks once it got to that temp. Helped clear the Duvel yeast and the result was pretty good. Unlike most, I did not re-yeast at bottling time and they still carbed up fine.
