value of wine

[Kcwhippet]

Welcome to the Board, bb. I can help on a few.

Winterbrook is a Modesto based winery (Gallo country), and most of their fruit is Central Valley sourced. The 1993 vintage was a fairly early maturing one. No real value.

Swanson makes small amounts of Chard from their vineyard on Oakville Cross Road. Fourteen years is probably a bit too long for this wine to be very much alive. No real value.

Never heard of Loh's Estates, but the Riverstone vineyard is owned by J. Lohr. The J. Lohr Riverstone Chard currently retails for about $12 to $14, and are best drunk within about 5 to 6 six years from vintage. No real value.

Hopefully another of the board's denizens can help with the rest.
