On the subject of surprising RS levels, I just opened a 2018 Carl von Schubert/Maximin Grünhaus Gutswein Riesling. Entry level bottling, apparently a blend of fruit from 3 grand cru vineyards and incredible value at less than $15 USD. LCBO says it has 10 g/L RS, their tech sheet says 8.1, but man, this is rattlingly acidic (8.4 g/L TA says same tech sheet), and during a hot year, too. Yowza! A wine I think even Adam could love.
It is a mistake to think that high acidity can always balance high RS - indeed you easily may have both: sour-sweet.
With 8.1 g RS and 8.4 TA it wouly be legally ok to label it dry, but I doubt itwould taste really dry - but 10g RS would be too high.
I know Schubert/Grünhaus quite well, and the Gutsriesling is usually excellent, but rarely tasting really dry (not to speak of bone-dry)
I’m repping a Niagara riesling right now in my Canadian monthly wine club, and I immediately thought of Adam’s rant.
The winemaker (Ryan Corrigan) told us he wanted to make a riesling that pairs with oysters. Bone dry.
Interesting style, in that it’s fermented in a combo of neutral puncheons and clay amphorae. Less than 2.0g/L RS.
Ryan says he gets a lot of weird looks when it’s poured among other Niagara rieslings. I’m not getting much of the tingling acidity… but more like the mid to end-palate salinity of a Muscadet.
The SKU is 2017 “Neptune” Riesling, by Rosewood Estates Winery.
