I made my first ever partial extract lager with a rice specialty grain and lager Yeast. I 2 stage fermented were the primary was at 70-72deg for 4 days and then secondary was at 36deg for 12 weeks. It was clear at that time and I tasted it before bottling and it was the best beer I have ever tasted. I bottled and naturally carbonated for 30 days at 62deg then refrigerated for 3 days. I was shocked at how much the flavor had changed and how cloudy it got. What went wrong?
