Two part question:
anyone know the formula for approx. % of alcohol by Vol. for OG reading and the FG. Had 1048 OG and 1010/11 FG after racking to secondary.
also had issued with autosiphon. noticed small stream of air bubbles as it did it’s thing. Am I in trouble ? 10 gal. on the line.
sorry, have one more. the bung kept popping out of one of my 5gal glass carboys.WTH
Here are some handy links.
http://www.brewheads.com/calc.phpPossible your beer will have a short shelf life because of the O2.
The bungs can have issues when wet.
ABV is (OG-FG) x 0.133, so in your case it’s (48-10)x0.133 = 5.1%
It’s quite possible that the bubbles in the autosiphon were CO2 coming out of solution, not air. Tighten your wormscrew a little to see if you can eliminate the bubbles.
Sanitize the bung, then wipe it with cheap vodka and allow to dry for 10-15 seconds and it’ll be squeeky dry and will stick to the glass.
