Until 1991, it was illegal for a farm in Delaware to have a winery on the premises, so the state's wine producing history is only 25 years old - a baby next to the old world wines of Europe and mature vineyards of Napa Valley on the West Coast.  There are only three wineries in operation now, and they're all worth a visit.

1. Nassau Valley Vineyards and Winery, Lewes

Nassau Valley led the way for wineries in the first state. They opened their doors in 1993, but their history dates back to 1987 with the first commercial vineyards in the state.

Tours and tastings are available year round. Self guided tours have visitors explore the history of wine and the vineyard. The venue is a popular location for romantic weddings.

Thirteen different wines are listed on the Nassau Valley website with everything from sweet red and white blends to dry chardonnays and merlots.

2. Pizzadili Vineyard and Winery, Felton

Rooted in strong Italian family history, the Pizzadili brothers kicked off the business by planting the first grapes in 1993.

Tours and tastings are available year round, but you must call first if you want a tour. The grounds are beautiful and there are several different venues for special events and weddings for up to 400 guests.

There are 12 different varieties of grapes planted on site. The brothers boast about their favorite wine, "Brothers' Table Wine," a dry red.

3. Harvest Ridge Winery, Marydel

Harvest Ridge is the newbie on the block, comparatively speaking, having opened their tasting room doors in 2013, on land that was purchased in 2005. The vineyard is on the western edge of the state, with some of the property in Maryland. There's a historic Mason-Dixon line marker on the property!

The tasting room at Harvest Ridge has an adjoining large event space. In addition to renting the space for the event, they often host fun tasting dinners, paint nights, food truck competitions and fundraisers at the winery.

According to Harvest Ridge, their location is perfect for growing grapes and the climate and soil is very similar to that of the Bordeaux region of France.

You can buy bottles (or a case) of wine from the tasting room, year round, or check out their online store. In addition to traditional varieties, be sure to sample a seasonal offering blended with local fruits.

We would love to hear from those of you who have visited all three. What's been your favorite?
