UPDATE:
Company email:
"I just got off the phone with Rich, who is a sales/marketing guy. He confirmed that all flavors except the Honey Basil* are vegan. The clarifying comes from a type of paper filter, and the particular brewing process that makes a clearer product. He couldn't expand on "type of paper filter" other than to say that the owner explained it to him several times and that it's definitely vegan."
Company email:
"I'm not certified vegan, but none of those things are used. Nothing else that is animal based, either."
