Does cultured butter have lactose?

Butter has virtually no lactose (and thus it is legal). Cultured butter is regular butter with a bacteria culture added to it to give it taste. This culture will eat up any lactose that remains in regular butter. So cultured butter has less lactose than regular butter. This is why (I think) Elaine says this is the best kind of butter for us.
