That's a tempting question. I wish I knew someone willing to spend a hundred bucks on two bottles of wine for me!

There's actually a lot you can choose from nowadays. Three good ones that should match that budget and not let you down are:
Torre Muga (Rioja)
Marqués de Griñón "Emeritvs"
Alión (Ribera del Duero)

But there's a whole slew of fancy Riojas, Ribera del Duero's for you to pick from.
