The diversity of Grenache will be on display as restaurants, wine merchants and producers celebrate the virtues of the world's most widely planted red grape.

Taking place on September 24, International Grenache Day will see events ranging from tastings to promotions and menu-pairings.

The idea for the day-long event originated at the First International Grenache Symposium in June when over 250 top Grenache producers, journalists, and retailers from 23 countries came together to debate the merits of the grape variety.

A Grenache "primer" is being distributed as part of a viral email campaign to help train and educate restaurateurs, retailers, sommeliers, kitchen staff, and servers in the diverse styles of Grenache and ideal serving and pairing options.

"Grenache is a remarkable grape due to its broad appeal and versatility," a spokesman said. "From white to rosé to sweet fortified wines, as light varietal reds or complex blends, it has historically and most famously hidden in blends from regions like Chateauneuf-du-Pape and Priorat - making great wines greater but lacking the brand recognition of varietals such as Chardonnay or Pinot Noir."
