17 days ago I made a batch of Java stout. The OG was 1.046. The first couple of days I had normal fermentation.. pretty slow at first, but good airlock action during the first 3 days... then all of a sudden it stopped. I have had this happen before and everything worked out fine, so I thought I would just wait it out and see what it does. I tested it right after it stopped bubbling and the gravity was at 1.035. I let it sit for 10 days and the gravity had dropped to 1.030. The temperature has fluctuated a little but not too much. The only thing I can think of is maybe I didn't get enough Oxygen into the wort before I pitched the yeast. Should i try to re-oxygenate the beer and pitch new yeast?
