Two short questions:
1. A fellow brewer recently returned a 5 gallon keg that he had cleaned and then sanitized with an idopher solution. The keg is about 3/4 full of this solution and I have never used idopher below so I am unsure if I just dump the sanitizer out and then use the keg or do I need to do several final rinses before using the keg? The solution has been in the keg for 2 weeks. I have only been using Starsan for my brewing.
2. Made my first attemp at yeast washing 2 weeks ago and I was able to collect 3 pint jars with white yeast sediment on the bottom. I know I should make a starter from the sediment a few days prior to brewing but what I don't know is what signs should I be looking for that will show me that the washed yeast is viable?
Thanks for any input.
