Brewday - "77 Ringwood Stout"

A fellow homebrewer provided a 2ml sample of the infamous Ringwood yeast.  Using my newly acquired stir plate (also donated), I was able to gradually step this to a final 1L starter volume.  Initial plans were to pitch to a pale ale; however, upon researching suggested styles for the yeast, I opted for a Stout.  Stout in the middle of summer?  Hell ya!  The photo below was taken approximately 15hrs from pitching.  I aerated the hell out of the wort.  I attacked it for 5 minutes with my Fizz-X (which I love BTW).  Open vessel fermentation FTW!

I plan to go direct from Primary to bottle.  Hydro sample was outstanding.

  1. Stepped 2ml of Ringwood Yeast provided by fellow homebrewer. Will pitch decanted 1L starter tomorrow morning once wort equalizes to cellar temperature. Still need to test starting gravity.

  2. Tested 1.053 although the final volume was slightly lower than I anticipated. Pitched my Ringwood yeast to a heavily aerated wort around 12 noon today. I've read online regarding a recommended 2nd aeration after 24hrs. This has to do with Ringwoods heavy oxygen demand.

    1. Chunky Krausen this morning! I suspect it started up sometime during the night. This would have put the lag-time somewhere is the neighborhood of 12-15hrs
