An acquired taste, I'm sure. I sampled Retsina once, and was not pleased! It tasted like turpentine, to me.
But I understand. Being from southern New England, I often wax poetic over clam cakes. Those who've never enjoyed them react with disgust when they learn what they are. Non-natives who sample them for the first time also react with disgust. Having grown up with them as a summertime seaside treat, I regard them as celestial ambrosia. De gustibus non est disputandum.
