Ok. So if I'm understanding this correctly, as long as your sanitation process is meticulous, you could drain say a gallon of chilled wort into your flask, aerate with oxygenate, pitch your yeast into the flask immediately (assuming it is at the proper fermentation temp) and then carefully add that to the main body of aerated wort when it reaches high krausen. Has anyone done this on a homebrew scale? I like the idea and many times weather, work and other conflicts have prevented me from pitching starters within 48 hours of making them. This process could also save one the time and expense of making starter wort and ensure a rapid start. What am I missing?
