i know at one stage they were advertising it on the container - i know nescafe was water processed. i now have a coffee machine so use ground blend rather than instant and use vittoria as they are water decaffenated also (again big letters on container tell me this LOL). I can't remember about moconna although drank it with pregnancy number 1 before I realised there was an issue with decaf and everything was fine. so maybe just look on the bottle and see whether it says water decaffinated somewhere - else maybe they have a customer enquiries number you could ring???
