I am mainly a Nigerian rancher. I got a mother and daughter Saanen recently and can’t seem to correct a distinct goaty aftertaste. I don’t have this issue with my Nigerians. Only this Saanen’s milk seems to have a chemical aftertaste. Any ideas on how to correct this? She’s got a clean environment and all of the milking tools are cleaned daily. Stumped on what to do or is this just the natural flavor of Saanen milk?
