Started my first kit two weeks ago (click). It's sitting in the carboy and airlock activity is nil. SG was 1.048 and current gravity is 1.020. I've never done beer before so do I just add the carbing sugar when the SG stops dropping and bottle? or is there an actual gravity value I'm shooting for?
You should take two sg readings two or three days apart - see if the gravity is stable. Also, I normally leave it in primary for three weeks before bottling. Your gravity is a little high, but not that unusual for an extract.
