This is my first batch ever, a Kolsch from a kit. It fermented like crazy the first 2 days, but after 4 had stopped bubbling, so I moved it to a secondary container. As I was transferring, I noticed a thick layer of lumpy light-tan sediment at the bottom of the primary, which I did not transfer. Is this where most of the yeast was? I'm now worried that there might not be enough yeast in the secondary to complete a proper amount of fermentation.
Also complicating matters is that a friend advised that I didn't need to take the OG reading.
So should I add more yeast into this secondary container?
