Which DOC would you associate with inexpensive wines made from Grechetto blended with Trebbiano and Malvasia?

The Orvieto DOC is indeed known for producing inexpensive wines that often include blends of Grechetto along with Trebbiano and Malvasia. Situated in the Umbria region of Italy, Orvieto is recognized for its white wines that can be fresh and crisp, making them approachable for many consumers. The blending of these grape varieties contributes to the wine's aromatic profile and balanced acidity, resulting in versatile wines that pair well with a variety of foods.

In contrast, the other DOCs mentioned are associated with different styles of wines or grape varieties. Frascati DOC, while also known for white wines, typically emphasizes different varietal combinations. Conero DOCG is primarily focused on red wines made from Montepulciano and Sangiovese, and Rosso Piceno DOC is known for blended red wines primarily composed of Montepulciano and Sangiovese as well. Thus, the unique characteristics of Orvieto DOC align well with the question regarding inexpensive wines made from the specific grape varieties mentioned.
