As the $1bn Constellation sale to Gallo goes through, we taste some of the brands in the deal. At inexpensive price points, are they worth buying - both from the perspective of the consumer as well as Gallo's? Wines tasted:

- Cook's California Champagne

- Nobilo Marlborough Sauvigon Blanc (also sold, though in a separate deal)

- Black Box Chardonnay

- Clos du Bois Pinot Noir

- Ravenswood Vintners Reserve Old-Vine Zinfandel
