anyone know what the real signicance is to the s type air lock versus the 3 piece. just curious. All i know is they say the s-type is better for secondary fermentation for some reason
I always use blow-off tube for the first 4-5 days, then S type. I find you are much less likely to get whatever you've filled the airlock with sucked backed into the fermenter with the S type, and they require less refilling (for longer fermentations.)
I use both, 3 piece is alot easier to clean. But I like the sound of the bubbles coming from the s type. Sometimes I listen to the sound in bed, it is like a lullaby. It is such a beautiful sound. Blurp, Blurp, Blurp, glipp, Blurp , Blurp, ahhhhhhhhhhhhhhhhhhhhh!
