Chogo (調合): Blending and Adjusting Sake for Consistent Quality

Two tanks of sake sit side by side in a storage building. Same rice, same yeast, same recipe, same brewing season. Yet one tastes rounder, while the other carries sharper acidity. So what happens next? Somebody tastes both, then decides how the finished sake should reach the bottle.
