And are you implying that the Star-San and 1-step cleaners are never really sanitizing the brewing equipment?
Sorry about the confusion. The distinction is between Sanit
izing and Steril
izing. Sanitizing merely lowers the count of living contaminants to a specified degree. Sterilizing lowers that level to zero living contaminants (including spores and such)
StarSan is definitely an effective sanitizer
. When used according to the label, Starsan will effectively lower contamination levels to an acceptable, sanitary level. One-Step, last I looked, no longer carries the sanitizer label because in order to do so they need to be FDA registered as a sanitizer (read $$$ for testing the product's sanitizing ability). For this reason 1-step can only be considered a cleanser.
In the case of yeast banks of any kind, you NEED to have sterile conditions, and this requires autoclaving everything
you use; vials, water, glycerin, utensils, etc.
