I brewed a double batch of premium american lager the other week and NC into 2 cubes. Last night had planned to dump them both into the 60L fermenter and use some saved yeast from Bohpils which I racked. Opened the first, all smelled nice and dumped it, opened the second and initially got a strong smell of plastic/chlorine smell, no smell of wort at all. Just inside the openening of the cube was some white sludge. Last time I had an infection in the cube the thing swelled up pretty quickly while the bacteria did it's job, this time there was just a sludge and no smell. I decided not to risk the whole lot and recapped the cube.
I took a smell of the cube today and there wasn't the strong chemical smell, but I could smell the wort, so maybe the initial hit of the gas in the cube last night stopped me from smelling other things? Any idea what could cause the smell/slugde. I always soak the inside of cubes in napisan unscented and rinse with cold water 3 or 4 times.
I tested the grav in the fermenter and it was 1.074 instead of the target 1.056. When draining to the 2 cubes is it normal for one cube to be higher grav than the other? Is it like draining a mash where the first runnings is higher than second? I do top up 10L after the boil but don't think I would have filled one cube and then just topped up the other. Maybe I got more that 65% efficiency with the rice and better milling of the grains this time. Anyway, added 6L of water to get it down to target OG.
Hope the 40L of weizen I have is ok.
