I recently brewed a porter and, for the first time, left it in primary for the entire time, rather than moving it to secondary as I've done in the past. When I siphoned the finished product into my keg, I had trouble with the residual particles of yeast, hops, etc. mixing into the beer I was trying to move into my keg. Any advice on good ways to ensure the end product is as clear and particle-free as possible? I was pretty careful with the siphon and didn't end up with too much junk, but I did miss out on the last 1/2 gallon or so of beer in the fermenter because it had too many floaters. Sad.
