Pop Quiz - Yeast

[franc1969]

This chart makes me feel so much better about my recent fermentations. I used Syrah on Syrah, AMH on Zinfandel. Both from juice- the progress was about what is on your chart. I was pretty concerned that I had done something odd- AMH went faster than I thought and SYR slower, based on ScottLabs descriptions of 'slow' and 'moderate'. I am interested in how MLF goes with the different yeasts- do you keep runs separately through aging, or press and age altogether in the same carboys?
As far as nutrient goes- I actually found no issues when I missed the last addition of nutrients for all yeasts- this was juice so might be different with grapes. I ended up using just the package suggested amount, when I had planned 1.5x as cmason1957 says.

Attached is my progress chart for a Tannat I have going. The pH is really low at under 3.2 and I was concerned about it's progress which is why I'm taking almost daily readings. The AMH per Scott Labs is a slow fermenter with a low nutrient demand. I was concerned about the AMH and Syrah and although they are slightly behind I'm really not concerned at this point.

Simply due to the quantities and carboy sizes I can't keep them separate. I wish I could but I just mix them together after press. I sometimes skip nutrients as well but with the low pH I wanted to take every precaution.
