Someone please help. I am currently brewing a oatmeal stout. Start date is 4/3/11 OG= 1.0426. Today (4/13/11) I transfered into a secondary and took a reading SG= 1.03528. Why is it still so high? Tastes fine. The temp has been fluctuating alot though due to the weather (temp has varied between 65 and 75)......... What is going on?
