Don't know what retsina is,
Retsina is a greek wine, where fur three resin has been used as
a preservative (no, not that type...), and which gives it a
scent of turpentine. However the whole story reminded me of my
mother giving me castor oil when I had a bad cough. Who dared
cough after a good dram of castor oil??
Best regards from Niels in springtime Denmark, where the beech
leaves are as pretty end light green as ever.
