Winery suggestions in Orvieto

Hello all. My wife and I are going to Italy for 3 weeks in May. Will be spending four nights in Orvieto and would like some winery suggestions nearby. We have a car. I would prefer to not spend more than 40 Euro for four wines. Unless there's something absolutely exceptional, I might do a little more. This cost does not included food. Thank you for any help you get offer.

p.s. we're spending four nights in Montalcino and four nights in Florence as well, so we'll get our fill.
