Three wines that are certified organic

Organic wines have a growing following in this age of concern for the healthiness of food and drink. The term "organic" refers to wines that have been made from organically grown grapes, and vinified according to certain standards. Many people grow grapes using organic practices but their vineyards are not certified; some are certified but choose not to disclose it on the label; others pay extra for the right to use the certifying body's logo on their packaging. The main certifiers in Australia are Australian Certified Organic (the bud logo), and the National Association for Sustainable Agriculture, Australia (NASAA). These three wines all proudly display their certification.

Kalleske Fordson Single Vineyard Zinfandel 2017, Barossa Valley, $25

Score 92

This has an inky dark colour with strong purple tints and smells of flowers, herbs, spices and blackberry jam. It's very full-bodied and almost lusciously fruit-sweet in the middle with a firm structure of soft but persuasive tannins. Screw-cap; 14.5 per cent alcohol.

Ageing? Drink now to 2033.

Stockists include Nillumbik Cellars, Diamond Creek (Vic);

Temple Bruer Preservative Free Shiraz 2018, Riverland, Fleurieu and Barossa, $22

Score 89

This youngster has a very deep, dark purple-red colour; the bouquet sweetly blackberry-like and very ripe, while the palate is endowed with firm tannins. There's concentrated, ripe berry fruit beneath the tannins. Preservative-free means no sulphur dioxide has been added. Screw-cap; 14 per cent alcohol.

Ageing? Drink now to 2024.

Stockists include Dan Murphy's and BWS Australia-wide; Camperdown Cellars (NSW); Ritchie's (Vic).

Frankland Estate Isolation Ridge Vineyard Riesling 2018, Frankland River, $40

Score 96

This outstanding wine is lovely now and the track-record shows it will age superbly. Delightful aromas of myriad flowers and fresh herbs; frangipani, assorted citrus fruits. It's very intense and bright in the mouth, with vibrant fruit and acidity combining seamlessly. Expressive, refined, tautly focused. Screw-cap; 12.5 per cent alcohol.

Ageing? Drink now to 15 years.
