I like to do my primary fermentation in a bucket, easier to stir, easier to take hydro readings, etc.
The key to SNA is based on specific gravity and not really on time. To do it the way intended you add nutrients at specific gravities of fermentation because each one seems to be different based on yeast, temperature, oxygen levels, PH, etc.
You can use a wine thief or clean and sanitized turkey baster to extract and measure. I'm just a little paranoid so I use the bucket and just put in the sanitized hydro meter in to take the reading.
- As a general rule of thumb, I would say you could do the second addition in 24 hours, and the third after three days. But you really do want to go off of SG (specific gravity).
Hope this helps.
