The Grandi Langhe DOGC is hosting 3 days of tastings in May in southern Piedmont giving professionals a chance to taste Barolo, Barbaresco, Diano d'Alba, Dogliani, Roero, Roero Arneis - directly in the various municipalities of origin, to meet the producers.
The area is also famous for its truffles.
Browsing the Consorzio Turistico Langhe Monferrato Roero site Tartufo e Vino, I learned that hazelnut groves are an integral part of region's heritage.
Visitors can sign up for an Hazelnut Discovery and learn about "history and secrets of the unmistakable taste of the PGI Piemonte Hazelnut" with "guided tour of a small farm in the Upper Langa, from hazelnut grove through shelling and roasting to the production of choice sweets, learning some of the secrets of so intense and lingering a flavour. A tasting rounds off the tour."
Tour takes 90 minutes and is offered all year round. Cost is 30 Euros per person. Booking by 10 am the previous day to your preferred date is required. It is suggest to availability.
