I made my first batch a couple of months ago. It was a stout from an extract kit. I followed the directions and ended up with an OG of 1040 and a FG of 1008. The fermentation was pretty strong for about three days. After a week and a half I bottled it with brewers sugar (3/4 cup for a little over 5.5 gallons of beer). I used iodophor to sterilize everything, using a 1 tbsp iodophor/5 gallons of water solution. I just dunked the clean bottles in making sure the inside was coated with solution, and then let them drain upside-down for at least 10 minutes if not more. I stored the bottles in an area that was about 70 F.
Two weeks after bottling, I popped some open to try it. It was pretty good, although still had a bit of a "young" taste to it. It had decent carbonation. But I was rather surprised that there was absolutely no sediment at the bottom of any of the bottles I finished. Recently, after another two weeks, I have opened a few more, and although it seemed a bit drier to me, I still had no sediment.
I know there was yeast in the beer before I bottled since I had a good fermentation, and a nice layer of trub, but I was wondering if I killed my yeast while bottling, and the carbonation is just what is left from the initial fermentation. Or is it that there sometimes just isn't sediment with bottle conditioning (which I would find that rather unusual)?
