The Villa Bianchi has been recommended in a number of newspapers as good value for money white at about $14/bottle. It is quite widely available.
I really enjoyed this clean, crisp and dry drink. It reminds me a bit of a Pinot Grigio in a light style, but I am not sure what grape varieties are involved. If you belong to the ABC club (Anything But Chardonnay), but want something a bit more interesting than your standard Sauvignon Blanc, try this wine.
