I just completed my first transfer to my glass carboy for my German Style Light. I purchased an auto-siphon from the local brew store and it worked wonderfully. I filled the carboy with sanitize solution and siphoned out the solution to clean the siphon and hose. This brew already started out much clearer than my first brew after my primary fermentation. With the addition of a three day secondary fermentation to allow the brew to settle more this should be a very smooth batch.
