After 11 days in secondary The Wort seems to have developed a haze, I'm concerned about infection. I have placed it in the Refrigerator to Crash Cool, hope this clears it up. Plan to Prime with 3/4 cup corn sugar, but the LHBS guy suggested that I use Yeast in addition to priming sugar. Is this necessary? 1.071 OG- 1.017 SG at racking to secondary.
