If they weren't used in one season, the unopened jugs were stored in the basement in an undisturbed corner. One day I went down to that area of the basement and noticed the floor wet over a rather large area. Picking up one of the gallon jugs, one could see fine holes all over it like it had rubbed a porcupine. The jugs were about 6 months old and were in the process of totally breaking down. Also, if you plan on transferring the distilled water to another container, you risk airborne contamination.
Distilled water has a very flat, uninteresting taste.
