The following is the e-mail response from Caribou Coffee when asked which of their menu items are vegan:
Thank you for your email and thank you for your interest in Caribou Coffee.
As we have many different options that have numerous variables, such as milk choice and different flavoring options. So unfortunately we do not have a list constructed that contains all vegan options.
I can tell you all of our coffee (whole bean and dripped brew) are vegan, and we do offer soy milk as an option.
I hope this is helpful and if you have any additional questions please do not hesitate to contact us as your comments are very important to us.
