Since the first 1989 vintage, the bold, beefy, tannic estate-grown Pinot Noirs have attracted the most attention. Grapes from the hotter slope behind the winery yield a bold, strong- flavoured Back Block Pinot Noir with new oak influence and furry tannins that demand cellaring.By contrast, the Front Block Pinot Noir, aged in seasoned oak casks, is a fragrant, more supple and forward style.Grippy tannins are the hallmark of Glover's style, reflecting his firm opinions on the vital role of tannins during the aging of red wines."It's not the tannin I am promoting - it's longevity," he says. I am not after a "big Ocker" image - the tannins are there as a preservative.
