It was a special release this morning, so it wouldn’t have even been available at VSO yesterday. They do that all the time with post-event residuals. Did you not get the email from the LCBO this morning? It was in the Vintages Latest newsletter they send weekly. You may want to check your opt-in email subscriptions.
The event sounds great, I was sorry to have missed it. Add me to the list of those who did not think to check the VSO site for wines that are sold-out on the regular LCBO site. I’ve bought a few red Riojas over the years (usually from Lopez de Heredia) but have never tried any white Riojas. Based on your review, I picked up one bottle of the Vega Rioja Blanco to try.
