I'm puzzling over a very minor thing I find in a few of my beers. Difficult to properly describe but I'll do my best. Currently I have a nice pale ale on tap. It probably has too much hop flavor and aroma to nail the BJCP description, more of an IPA with lower end hop bitterness and on the low end of abv. It has no off flavors, it's properly carbonated, looks great, smells great. Upon taking a drink, it starts great and ends great, but there is a middle that seems, for lack of a better term, hollow.
I have two theories.
1. When you first take a drink it's full of carbonation, which amplifies everything, but as the carbonation diminishes it seems like the flavor and aroma and mouthfeel drop. Then after swallowing it kicks back up because now you have retronasal. In other words, nothing is wrong.
2. I'm missing some water ions and that is causing the mid palate hollow thing. My well is quite low in NaCl and I don't ads any.
The adjusted water on this beer is
