In anticipation of getting in the newest SandiSkerk wines from Oliver McCrum, I cracked on Fri night:
1. Skerk Terrano IGP: Venezia Giulia (15%;; OliverMcCrumImports) Prepotto 2011: Very dark/near black color; very intense Refosco/black cherry/boysenberry/RCCola bit peppery/licorice bit earthy/dusty rather complex nose; fairly tart/tangy very intense Refosco/black cherry cola/RCCola/licorice some earthy/dusty/peppery rather tannic/hard complex flavor w/ modest hard tannins; very long intense Refosco/black cherry cola/RCCola/boysenberry bit earthy/dusty/rustic slight herbal/thyme complex finish w/ modest rough/gritty tannins; a pretty classic Refosco but a bit on the rough/rustic side and needs more yrs for the tannins to resolve, if they ever will. $35.00 (VintBerk)
And a wee BloodyPulpit:
1. We tasted this wine almost 2 yrs ago:

that will go another 10 yrs; almost a Sforzato Teran; one of the best Terans I've had. $35.00 (VintBerk)

The wine seems to be getting a bit harder & more rustic in the last two yrs. Not sure it will ever outlast the tannins.
2. Terrano or Terran: This is a grape variety found mostly in the Kras region of Slovenia & Italy. According to Wikipedia:

I have no idea what that statement means and why the decline in bivalent iron is the death knell.
Several yrs ago, there was a move afoot to forbid the use of the grape name Teran/Terrano on the label unless it was grown on the Slovenian Karst/Kras. Don't know if that ever went thru or not.
