Lighter and livelier than the 2018 (a warmer vintage, which weighed in a full percent higher in finished alcohol by volume), Rippon's 2019 Mature Vine Riesling strikes a winning balance between fresh green apple, tangy citrus and spring-like florals. It's medium-bodied (12% alcohol) and almost dry, with great concentration and length. Classically built, it should age well for over a decade.

Apple, citrus and crushed-stone notes all mingle easily on the nose of the 2018 Mature Vine Riesling. It's a steely, nearly dry and powerful wine, with ample weight on the palate and tremendous length, the crisp finish echoing with hints of apple, lime, vegetable oil and dried spices and ending on texturally edgy granules of decomposing granite.

The off-dry 2016 Mature Vine Riesling (8.2 grams per liter residual sugar) offers hints of petrol and beeswax on the nose and flavors of peach, mandarin and lime. It's medium to full-bodied, richly textured and features a lingering finish of lime zest and sherbet. It spent 100 days on its primary lees to build texture. Like the 2015, it's another terrific Riesling.

The 2015 Mature Vine Riesling shows hints of honey and bergamot on the nose, followed by a medium-bodied, barely off-dry expression. It shows enormous richness of texture not often found in New World Riesling married to fruit that comes across as savory, despite the hints of honey, peach and citrus lurking within. Then those mouthwatering flavors linger on the finish. It's a true tour de force.
