I must be doing it wrong because every time I rack from the brew pot to the fermenter I get hops clogged in the auto-siphon. After cooling, I stir in order to create a whirlpool and let it sit for 15 minutes. I try to hold the siphon high in order to avoid any hop remnants, I use plugs. But bits of hops get caught. I do 3 gal. boils so that may affect it too.
