An essential part of a good fermentation is healthy yeast.
In this Technical Presentation Brittney Christianson of Lallemand Brewing provides an overview of yeast nutrition basics for all-wort and sugar-based fermentations.
This 20 minute webinar will cover:
What nutrients wort provides yeast
The nutrient mix yeast needs for a good fermentation
The importance of nitrogen, zinc and oxygen to your yeast

I have made a home scale very small Bioreactor for growing up yeast cultures of Kveik Yeast for drying and freezing yeast slurry , Its a 1 quart to 1/2 gallon reactor depending on which jar i use. Basically its a ball airlock lid( the kind for fermenting vegetables with a built in airlock) that i drilled a second hole in and put a stainless steel air stone that is hooked to an air pump and it sits on a Stir plate, so, if my understanding of the process is correct this would be a Very Basic Bioreactor. My issue is the feeding schedule for optimum yeast growth and how much sugar and nutrient i should be feeding it daily. I have Fermax yeast Nutrient and I am doing my Grow up with white Table sugar because its a cheap easy sugar source. I am building up a personal yeast bank of Kveik yeast strains for use in Home wine,beer and mead making. So My goal is the highest biomass I can achieve with the limits of my home made set up. My reactor it self is working so far I am just not sure on a rough estimate of how much sugar and nutrient to feed it daily. I dont have a super accurate Gram scale(yet) so I am using measuring spoons and cups at this point At the present time, I am doing roughly 1/2 teaspoon of yeast nutrient and about 1/4 cup of sugar daily in a 1 quart volume of water I was wondering how these amounts look and if i should change them, if so how much of each would you suggest. The yeast nutrient I have is a General purpose nutrient designed for home wine,beer and mead making. My sugar source is currently white table sugar due to price and ease of access. Any suggestions you can offer would be greatly appreciated.
