Great podcast. While some may have found the chemistry too much, I can’t wait for the follow-up episode. I especially liked John’s thoughts on adjusting water profiles to ‘match’ classic brewing styles that evolved to work with the local water. The idea of small adjustments instead of trying to recreate the water makes a lot of sense and is on my list to try next brew day.

For John, I’ve been on the list with Amazon for a copy of the book for months. Can’t wait.

All the best…
