Great lineup. Glad you enjoyed your first Washington wine and that it survived the trans-Atlantic hurdle. Cadence is among my top three for WA. The Ciel du Cheval is always my favorite and we just tasted the '01 and it surpasses its reputation.
The vineyard is on Red Mountain, not in Walla Walla.
One correction. It retails for around $35, which is still exceptional QPR. It sells out quickly - '00 long gone. At $20, it wouldn't last a New York minute, which is roughly an hour in Washington.
