I use a robobrew v2 for mashing, but threw the malt pipe into storage and just use a grain bag on the false bottom to be able to use way more grain. I use the pump to recirculate wort from the bottom where the heating element is to a floating mash cap with a 1/2" barb added in the middle for the wort to flow through. I turn off the pump when I reach mash out temp and slowly drain the wort to a boil kettle through the bottom ball valve while adding sparge water through the mash cap fitting. If I fly sparge like that very slowly, I get 90%+ efficiency but noticed yesterday that I kept getting an air pocket in the hose to the boil kettle right at the barb if I throttled the ball valve down that far. I ended up having to sparge way faster to avoid the air in the line and my efficiency dropped to 78%. I don't understand where the air was coming from, I have teflon tape on all connections and 3/8" silicone hose forced on the 1/2" barb! any ideas on how to tighten this thing up?
Also, did this 10-15 seconds of air infusion make this a highdo beer, I used 40mg/l smb in the mash and 15mg/l in the sparge water. I should have practiced with just water...
