Slightly, not too much. All I ever did was throw in some coffee grounds at transplant time. Coffee grounds are very slightly acidic. Not enough to really make all your soil acidic, but locally around each plant it seems to give the peppers what they need without going to the trouble of making the whole soil acidic.
ie... If you did a test of the over-all soil Ph even where the grounds are, it won't have changed much, but the tiny root hairs directly touching a particle of coffee grounds can pick up whatever it needs.
