Whisk in the half and half, then stir in the potatoes, rosemary and thyme.
Cook over medium heat, being careful to not let the soup boil, until the potatoes are tender about 15 minutes.
Stir in the reserved clams, reserved bacon, and red wine vinegar. Season to taste with salt and pepper.
Cook until heated through, another minute or two, and serve.
