Frankland Estate was established in 1988 in Western Australia by Barrie Smith and Judi Cullam, who are now assisted by their daughter Elizabeth Smith and son Hunter Smith and a small team of workers. The aim is to produce wines that reflect location, soil and vineyard environment rather than the technical prowess of a winemaker. The winery makes admirable chardonnay and shiraz-based wines, but the rieslings, reviewed here in their versions of 2012, are particularly compelling for their purity, concentration and intensity as well as their immense pleasurable qualities. The wines have been certified organic since 2010. The wines of Frankland Estate are imported by Quintessential, Napa, Calif. Tasted at a trade event in Chicago on May 15, 2013. Three of the label illustrations are one vintage behind.

Frankland Estate’s entry-level riesling among new releases is the Rocky Gully Riesling 2012, a wine lovely in its varietal purity and intensity, in its scintillating limestone minerality, its hints of lemon, lime peel and yellow plum, jasmine and lychee; keen acidity flings a bright arrow from a taut bow-string (not to get carried away by metaphor, you know), while the limestone and flint elements are drawn out finely through the finish. Complicated? Multi-layered? No. Authentic and thoroughly enjoyable? Absolutely. 11 percent alcohol. Drink now through 2015 to ’17. Very Good+. About $21.
Next up the scale in price and a different sort of wine is the Frankland Estate Smith Cullum Off Dry Riesling 2012, fermented with wild yeast in 1,000-liter French oak barrels, a bit more than four times the size of a standard barrique. The balance here is exquisite, and the wine displays tremendous energy and liveliness, great tension and litheness; it’s the sort of wine you don’t want to stop sipping because it feels so good. Delicious, too, with touches of lime peel, grapefruit and lychee, hints of rubber eraser, ripe peach and lilac; nor does it neglect the necessary crisp acidity and chiseled limestone minerality, though fruit is the raison d’etre. 10.3 percent alcohol. Now through 2017 to ’20. Excellent. About $26.
Made from vines planted in 1966, the Frankland Estate Netley Road Riesling 2012 sees only stainless steel in its production, and one understands the motivation; why not give the 46-year-old vines and their grapes the chance to express themselves in the least manipulated manner? The wine is very clean, very bright and engaging, filled with vibrancy and animation yet surprisingly delicate and elegant. Notes of roasted lemon and lemon balm are buoyed by hints of cloves, quince and ginger and a backwash of lychee and oyster-shell; that mineral element carries through to the finish on a tide of limestone and flint and bracing salinity. Lots of power here yet beautifully elusive and ephemeral. 12 percent alcohol. Best from 2014 through 2020 or ’22. Exceptional. About $28.50.
The Frankland Estate Poison Hill Riesling 2012, made completely in stainless steel, brings fruit and mineral elements into perfect balance, which is to say that it’s the most fruit-forward of this group of rieslings yet it steadfastly maintains its foundation in a rigorous structure of brisk acidity and mineral elements that feel crystalline. The wine is vibrant and vividly dynamic, almost glinting with limestone and shale qualities, and it’s quite dry, though the texture feels soft and ripe on the palate, and flavors of roasted lemon, pear, lychee and peach are downright tasty. 12 percent alcohol. Now through 2018 to 2020. Excellent. About $28.50.

The flagship here is the Frankland Estate Isolation Ridge Riesling 2012, made partly in stainless steel, partly in neutral oak barrels, that is, barrels previously used to the point that the wood influence is subtle if not subliminal, which is certainly the case with this wine. This is a lovely riesling, offering wonderful appeal, resonance and elan, yet its primary state for now and perhaps the next six to eight years is of a scrupulous and definitive structure of lithe and austere limestone minerality and whiplash acidity. 11 percent alcohol. Try from 2015 or ’16 through 2020 to ’24. Excellent. About $35.
