Stuart is partially right. Ascorbic acid (Vit C) helps gluten development and makes lighter breads.
Regarding the spice additives mentioned above, the amounts used should be just a pinch because at high levels they work against rising. Amts should be under 1/4 tsp per cup of flour.
BTW, I failed to mention another reason that the sourdough bread is coming out dense. Wetter doughs will rise better than drier, flour-filled ones. So be judicious adding flour when kneading. If you knead long enough, a slightly sticky dough will suddenly turn beautifully elastic.
A general rule of thumb for breads, after kneading, to see if they have to much water or not is to shape the dough into a ball and slap your palm on it. Let it there for 10 seconds. If you then pull your hand off and dough sticks to it, it's too wet; conversely, if dough doesn't quite stick, it's just right.
