91+ Mark Squires - Robert Parker's Wine Advocate

"The 2017 Riesling Argetsinger Vineyard, another late release, has just three grams of sugar (owner Morton Hallgren said, "Our sugar analysis is only accurate down to plus or minus one gram per liter, so it can be between two and four grams per liter") plus eight grams of total acidity. It comes in at 12.7% alcohol. Steely, deep and perhaps a touch reductive, this powerful Riesling is another classic from this vineyard. It's not for the shy, though, and winemaker Morton Hallgren has built this for the long haul. As it airs out and warms, this gripping Riesling becomes a little friendlier, but only a little. It's not entirely clear where the ceiling is for this wine just yet, but let's start here and see where it goes in time. It does need to come into better balance. If you like your Rieslings softer and sweeter, this isn't going to be for you. It definitely needs a food pairing—and perhaps a bit more cellar time."
