A lot of the folks mentioned upstream are buying fruit from Houyi (past tense now its owned by Realm) and Melanson. Dont know many others selling fruit. If I am not mistaken, there are only 10 estate wineries on the hill -
Chappellet
Colgin
CONTINUUM
Bryant
Gandona
BRAND
OVID
David Arthur
REALM
Del Dotto
As for wineries with estate vineyards, Bryant has pulled things in drastically and are making outstanding expressions of that hill. OVID also with Austin Peterson who is one of the most brilliant winemaker/viticulturists in Napa Valley. He has also been pulling in extraction and oak usage a lot over the last several vintages.
Gandona and BRAND have new winemaking teams in place but 23’s will be first vintage for new team at Gandona and Brand will be the 24’s - Both are now Graeme MacDonald.
I’ve searched out Pritchard Hill wines for years so was all over wines from Houyi (Bevan, 9 Suns) and stopped buying for reasons you mentioned. With my eyes closed I could never tell they were from Pritchard Hill and they just lacked that something compelling to make me keep shelling out $150+ for them.
Hopefully Realm can tease something more out of the site.
For me, the “king” of Pritchard Hill is actually the “queen” of the hill, Helen Turley. There had been wines off the hill for decades, but what she did with Bryant and Colgin in the 1992-1997 time frame was literally to make PH the Rodeo Drive of Napa. She made the hill and her effects are still felt all this time later.
