I'm constructing a german wheat ale and I have a question. It took about 36 hours for fermentation to start, after that it bubbled like mad for about 18 hours, and then shutoff completely. Should I wait to rack the beer to the secondary any longer?......the instructions I got in the past say wait 5-7 days.....it has been 4 days since yeast pitch....I'm in a time crunch.....this needs to be ready for Christmas.......thanks.......oh yeah, it has been cold here at my location, Texas,......60 to 75 degrees F
