No, they do not. If you have allergies or dietary requirements that necessitate avoiding things like dairy, nuts, fruits etc then you do not need to worry.
The descriptors that we use for our coffees are just a way of communicating the things that we think each coffee tastes like. All of our coffees are 100% unadulterated and the flavours present are created by the type of coffee plant, where it's grown, how it's processed, and how it's roasted - no additions of other things, just 100% roasted coffee in the bags and nothing else :)
Our production facility is compliant with all HACCP and Environmental Health requirements relating to food safety and allergens. If you require more information please get in touch at orders@ozonecoffee.co.uk.
