First let me say I've only made two batches of beer. So I'm still a newbie. When I made my last batch, a honey wheat, I siphoned from the kettle to the fermenter. I didn't pour all of the wort in. There was an inch or so of sludge, for lack of a better term, in the bottom of the kettle. Do I pour everything from the kettle in? Or siphon and leave the residue on the bottom? The beer turned out fine, just wanting to get the most out of it.
