I started using the tailored organic staggered nutrient addition (TOSNA) protocol in my mead-making. I have yet to run any one-to-one tests between TOSNA and non-TOSNA brews, but I assume the former is significantly better than a one-time addition of Fermaid-O, and even better than a one-time addition of DAP. Most homebrewers writing online are unified that staggered nutrient additions, and Fermaid O + GoFERM in particular, are superior yeast nutrient regimens than other approaches. Now, they are almost certainly correct. The theoretical arguments I have read about reducing off-flavors and keeping fermentation temperatures down seem plausible, and I do not imagine that so many serious mead-makers are completely wrong. However, there is very little (if any) published research about yeast nutrition to support these claims, so far as I can tell. Where is the evidence for TOSNA's detailed protocols? Where are the publications that support the many claims made about it?
Again, I'm not asking these questions to cast doubt on TOSNA; rather, it is just odd to me that we seem to be at the mercy of anecdotal evidence for proper yeast nutrition. Am I right in that conclusion?
