A F.G. of 1.007 should be a dry beer.  The beer could lack bitterness.  However, the flavor of pilsner malt definitely leaves a graham cracker sweetness on the tongue.

Less like a cracker/bread and more like tart and maybe a bit citrus.  Now that I think about it, seems more like acetaldehyde than ester (no banana).  Maybe in retrospect I should have d-rested for longer.  Well I suppose the good news is I think there's still plenty of yeast in my secondary to perhaps clean it up during lagering...   Thinking about bringing it back to D-rest temperatures again for a few more days clean out some acetaldehyde if indeed that's the issue

If not, then hopefully the cold/carbonation will help mellow it out.

I have had many beers taste off in different ways when I have sampled them short of being completely finished, meaning bottle conditioned or fully carbonated in a keg. I feel like when I taste them at this early stage there are likely to be flavors that will transform or go away. I also think that when I am tasting at this stage I am actively seeking flaws and may find ones that are not necessarily really there. A sort of confirmation bias. Maybe I was worried about fermentation temp and sure enough some fruity esters or what not. I often end up loving beers when I am simply drinking them that I had been concerned about during the process.
Don't let the bastards cheer you up.

Curious what does the gypsum do?  Just change the water profile to emphasize the hops over malt/sweetness?  Here's the profile I was aiming for:

50ppm CA, 4ppm Mg, 16ppm Na, 55pm CL, 58ppm SO4


First, I am no expert on water chemistry. Far more brewers have far more knowledge than I do.

Having said that, yes, the sulfate will give a ‘sharper’ hoppiness. You can add gypsum after the fact to dose your beer to test this.

Likewise, you can add Calcium Chloride to accentuate a malty perception.

The profile you targeted was a neutral or balanced profile because the chloride (Cl) and sulfate (SO4) are about the same (underlined above). You can tilt it towards one or the other to create a more malty or more bitter profile.

To make fine tune adjustments to taste, the SO4/Cl ratio can be tweaked.  I use John Palmer’s range as a guide:

    * 0.6-0.8: Malty
    * 0.8-1.5: Balanced (you’re at 1.05)
    * 1.5-2.0: Slightly Bitter
