hey guys, got a problem. i made a midwest irsh red ale. i've opened 4 of them so far and all seem to have sort of a watery taste and varying degrees of flat. i usually open a beer about 1.5-2 weeks in bottle to check carbing and found that one to be almost completely flat. they have now been in the bottle for 4.5 weeks(grolsch bottles with 2 uses on the seals). i only did two things different than the last 4 brews, left in primary 4 days longer, and normally i use vodka to remove the bubbles left from star stan in the bottles. this time i did not not, and i fear that too much sanitizer was left in the bottle. just wondering of anyone cares to chime in on this one.
