while visiting DP, they told me that 05 is only available in a very limited qtty and thus will only be available for a short time
They say that to everyone (about most vintages) to preserve the image that the wine is "exclusive" and therefore able to charge a "scarcity" premium, when the reality is, they have absolutely tons of the stuff - just take the hundreds of cases served daily by EK, which is only one airline customer!
After all, they must keep some back to launch the Plénitude re-releases every so often
