... I would be interesting to see if BRY-97 started faster when underpitched when pitched into well-aerated wort. Dry yeast can make a brewer lazy in the aeration department because of its reduced dissolved O2 requirements
I can add anecdotal evidence to aerated vs non aerated wort if underpitching Bry-97: when I first began trying to make Bry-97 start faster I first tried aeration with the ‘one pack in a batch’ method. I’ve personally experienced 36 hr long lag times.
So, I went down and bought the O2 bottle and regulator. I didn’t notice a discernible difference. I still saw long lag times. Frankly, I don’t remember if they were less than 36 hrs or not but I recall be frustrated.
After a conversation with a company rep and fellow brewers, what ended up working for me was pitching to the mfr recommended weight per SG and volume coupled with their method of pitching while filling and pitching yeast nutrient along with the yeast.
Using this method I get remarkable 16 hr +/-2 hr lag consistency. I don’t even know where the O2 bottle is anymore.
