acetose

Nothing gloomy, nor acetose, nor piously-angular can be observed in them; nothing pre-eminently lustrous is seen in the halo of the respective worshippers; yet there is a finish about them which indicates that they have no connection with the canaille, and that they are in some instances approaching, and in others directly associated with, the “higher middle class.”

Sour, acid, tart, acrid, acidulous, acetose, acerbitous, astringent.
