The fifth beer that I brewed.
This beer was so defective that there was no workaround for it, and I had to throw away the whole batch.
The fact that it was a Blonde Ale also helped, as it is a style that is quite “straight to the point”, where all the off-flavors are quite noticeable.

Notes
The beer had a heavy presence of chlorophenol and I considered it undrinkable. Due to that, the whole batch was thrown away.
The causes that were considered the most probable were the use of old grains (the malt was given to me by a friend who had them as leftovers) and chlorine presence in the water (by using the unfiltered line instead of the filtered one).
