Catherine Keith and her father Tony Rutherford established Mount Brown in 2002 by purchasing a mature vineyard in the Waipara Valley. They have further extended their holdings to three vineyards, and the resource of old vines plays a significant part in the quality of the wines that are being made by winemaker Frank Manifold. Mount Brown has placed itself at offering very good value, and this has helped them grow their market share. The brand is certainly becoming more visible. Here, I review the 2017 Mount Brown Riesling. www.mountbrown.co.nz
