Its really frustrating...I've seen them go for $135 + BP, plus tax, plus shipping. I get it a high demand wine would go for over its release price, but this wine is out of control.
What I have heard is that the winery has specific buying requirements for their other wines before you can get the Rosado or even some of their whites. Something like you need to buy X number of cases of the red reservas before they can allot you a shipment of the rosado. This in part is what drives up the price.
