Your suggestions on the best under $15

[Scoop]

For another Cali choice, Markham produces a decent SB for around $10. Still, I generally opt for the NZs and Sancerres mentioned by IK (and don't forget the other Loire SB appellations Menetou Salon, Quincy and Pouilly Fume) -- they just bring more finesse, complexity and acidity to the table. Also, Chateau Bonnet is a very consistent SB blend (with Semillion and Muscadelle) from Bordeaux (Entre Deux Mers) that will only set you back around $7.

Cheers,
