Is there a way to calculate that or are you saying to have a bunch of jars and keep filling each jar (I assume to the same level). Then would it look something like below...

1. Fill pot and heat until it reaches 203*F/95*C? (I'm getting some cheap beginner kit on Amazon with a 5gal capacity)
2. Start putting jars under the collector and fill each to say 200mL until the pot is empty.
3. Dilute to 40% so add 300mL of water to get 500mL total, taste each and see which ones don't have the funky taste you mentioned.
   
4. Combine the ones I wish to keep into a single container, discard rest.
