I brewed it this past weekend. OG was just about dead on at 1.064. Since this is my first beer I have a couple of questions about fermentation. My plan is to rack on the fruit puree in the secondary after it reaches fg. I'm taking my first hydro reading at 7 days (tonight). Is it correct to wait until primary is completely finished? Also, is it necessary to move it to a third carboy for clarification ?
