Wow.  For some reason, the JJ Prum 2015 wines have not shut down.  This one is amazing.  It will get better as well and probably has 50 years of great drinking ahead.  One of the truly great wines out there and when one factors in price, there are not many better values.  This was from a 375ml bottle.  Light golden in color.  The nose is clean with minerals, wet rocks and slight peach and grapefruit.  On the palate, this is sweet, not cloying.  Great acidity.  More about minerals but some stone fruit.  Deep and contemplating.  Long finish.  Spectacular.
