Before you use it
Organic nitrogen is roughly a fifth as concentrated as DAP by weight, so the doses look large next to a nutrient blend. That is the product, not a mistake.
Description
Yeast autolysate: nitrogen the yeast digests out of dead yeast rather than out of a salt, which is why it feeds steadily instead of all at once. The organic backbone of TOSNA, and OMRI-listed, so it suits meads and ciders that want no synthetic nitrogen.
