Starbucks has unveiled its most expensive coffee yet -- a rare Costa Rican blend that will cost you $7 for a large cup.

Made from a rare, heirloom, hard-to-grow coffee bean called "Geisha," the "Costa Rica Finca Palmilera" costs $40 for a half-pound bag, $6 for a tall cup and $7 for a grande, the Seattle Post-Intelligencer reported.

For now, it's only available in select Pacific Northwest locations.

But Starbucks plans to offer the premium Geisha blend nationwide as early as next year.

The real question may be, will anyone buy it?

If coffee nerds are any indication, plenty.

Java aficionados are loving it, according to the Post-Intelligencer, and an online Starbucks offering of the blend this month sold out in just 24 hours.
