Wulf, How much and where/when is your water classes you mention... I am very much interested in attending to see if I am doing things properly.

However, I have/plan on further treating my stored water when/if i need them.

My current process:
- Save 2-liter soft drink bottles as I use them.
- When I do homebrewing at home I use my left over sanitizer (Star-San)to sanitize the clean 2-liter bottles, and immediately fill/seal the bottles with Aurora Tap water.
- Stack the bottles in a cool-dry crawlspace under the house using repurposed 2-liter bottle plastic trays that hold 8.
