First off, a riddle:
You have an old time balance scale (see pic) and 8 balls of all the same size...no difference except one weighs less than the others. You can use the scale twice, no more. How do you definitively figure out which ball weighs the less? Answer at the very bottom:
So, I have a dry stout that tastes sour...kinda plastic-like...very unappealing. I used irish yeast and was afraid I had a bad yeast ester thing going on, but it was too strong a taste. So I took it to the LHBS to give them a taste. They picked it up as well and said most likely culprit was water chemistry. I also have a Nalgene bottle that I keep filled up with pre-boiled water that I didnt think to mention while at the shop.
Spoiler alert: I have three scenarios to check: 1) brew with pure RO water and build up a profile 2) brew with straight tap water 3) water isnt the problem, its the nalgene that is throwing the off-flavor. I plan on making two half batches using 1 and 2, if neither are the problem, it's curtains for my nalgene bottle.
Answer to the riddle:
you pick 3 balls for one side of the scale, 3 for the other. If they weigh the same, you put the other 2 balls on the scale, one to each side.
IF they do not weigh the same, you take the three from the lighter side, pick 2 and weigh them. If they are different, you found the lighter. If they are the same, the one you didnt put on there is the culprit.
