It's a worth trying local wine, most of all if someone will offer you its own from a fresh and old cellar. In the region of Latera there are some famous wines, such as Est Est Est! produced in Montefiascone and Aleatico, in the bordering town of Gradoli. The tuscanian towns of Scansano and Montalcino, famous for their Morellino and Brunello, are not far from Latera and you'll be able to appreciate their wines in restaurants.
Latera was once a town rich of spring water. A lot of sources were sold in 1970's by local administration. Now you can find some water fountains, but they have been marked as not drinkable. Don't worry if local people invite you to drink that water, they'll say "I've grown up drinking this water, is fresh and good and I've never felt bad". The water is in fact tasty and fresh, but drink it at your risk: you could be the first one to feel bad.
