Should have made this more clear...

The "sharp" tasting beer is the fresh one, in the keg 4 days. It had chemicals added to the water. Very good, with an edge to the flavor. More hoppy.

The "mellow, smooth, well balanced" beer is the one that is about 6 weeks old, with standard tap water (filtered). Good, more malty.

If gypsum was the major addition then your hops should be a little sharper and the beer should be a little dryer.

Yes, Gypsum and CaCl2. That's it. The beer turned out so good, brewed up another 10 gallons yesterday, Classic German Pils. But TexMalt was used this time...it's a long shot.
