Alkina Wine Estate

Last verified · September 2026

Most Barossa reds are made to be recognised. Alkina's are made to be told apart. The estate is at Greenock, on the western side of the valley, and instead of blending its Grenache into one house style it splits the vineyard into numbered plots and bottles them separately — Polygon No. 3 is the one the Halliday Wine Companion scored 97.

That is an expensive way to farm and an expensive way to sell. Small parcels mean small ferments, more vessels, more labels and a bottle that costs about a hundred and twenty US dollars, in a region whose reputation was built on generous reds at a fraction of that. It only works if the plots really do taste different from each other.

Barossa Grenache is worth meeting on its own terms. It is not the region's famous Shiraz: lighter in colour, higher in perfume, red-fruited rather than black, and it has spent the last decade being taken seriously by growers who used to treat it as blending material.

The certification is the tidiest on this page. Southern Cross Certified's register carries certificate 24068 for the whole estate, and it lists organic and biodynamic against every single product line rather than a subset — Grenache, Shiraz, Mataro, Cinsault, Grenache Blanc, Clairette and the rest. The row previously read "ACO / Demeter (verify)" and the press had said NASAA; the register settles it.

Why it’s remarkable

Every product line
the certificate does not stop at the flagship
Southern Cross Certified's register carries certificate 24068 for the estate and lists both the National Standard Organic and the National Standard Bio-Dynamic marks against every product line — Grenache, Shiraz, Mataro, Cinsault, Grenache Blanc, Clairette and the rest. Scope is where organic claims usually thin out, and this one does not.
Numbered plots
the vineyard is bottled in pieces rather than blended
Rather than making one house style, the estate splits the vineyard and bottles the parcels separately; Polygon No. 3 is the bottling the Halliday Wine Companion scored 97. Small parcels mean small ferments, more vessels and more labels, and it only justifies itself if the plots genuinely taste different.
About US$120
a price the Barossa's reputation does not prepare you for
The Barossa built its name on generous reds at accessible prices. A hundred and twenty dollars for a Grenache from Greenock is a bet that a region known for value will be paid for precision instead, which is a harder sell than making another big Shiraz.
