I have 2gal of oktoberfest slowly bubbling in my cellar. I went with 2 gal simply b/c I didn't have time in advance for a starter and figured 2 gal would be more like an oversized starter and give me some yeast for some 5 gal batches I want to brew. Problem is I was planning to brew tomorrow but not sure what racking would do to the octoberfest while its still bubblin slowly? My ideas are to rack it and save the cake, or tip the carboy and attempt to syphon off some off the cake, or shake the heck out of it and just draw a couple cups off. What would be the best or should I just wait til its done fermenting?
