McWilliam's, one of Australia's oldest wineries, has joined the growing number number of producers using the stelvin screwcap closure.

The family owned McWilliam's has wineries in three states and the screwcap is on one of six new regional varietal wines, a Riesling from the Clare Valley.

McWilliam's thus joins the band of Australian Riesling makers - and Sauvignon Blanc makers in New Zealand - using the screwcap to prevent cork taint.

And it may not stop there. A McWilliam's spokesman told just-drinks.com that the company was experimenting with stelvin closures on Semillon wines. Semillon from the Hunter Valley of New South Wales has a reputation for longevity and McWilliam's is a leading maker.

Stelvin was used by the South Australian producer Yalumba in the 1970s but consumer resistance meant most companies stayed with cork until concerns about tainted wine prompted a rethink.
