Harbes Western Farm started in 1978, when newlyweds Ed and Monica Harbes bought some land and began growing potatoes and cabbages to support their family. Ed, a 13th-generation farmer, worked with his father to get the business up and running. As the years passed, the couple's children started to work on the farm as well. Eventually, all the family's tomatoes, sweet corn, and growing brood of scarecrows outgrew their original plot of land, and the family expanded into three separate locations—which Ed and Monica's eight children still operate.

As the Harbes plow and harvest the fields, visitors at each location can stock up on fresh produce and participate in seasonal activities. An 6-acre Wild West corn maze draws visitors to Jamesport farm, whereas at Riverhead farm, the fall season brings opportunities to pick apples and pumpkins. Another 5-acre Robin Hood-themed corn maze entertains the masses while a spooky moonlight corn maze cast spells of fall splendor. Visitors to the Mattituck location—the largest farm—can shop for fresh produce in the market or relax in the wine-tasting barn. Amid its warming and inviting wood walls, servers pour selections from Harbes Family Farm & Vineyard's award-winning wines, which Winemaker Ed Harbes IV creates using his vineyard's vinifera clones.

But as much as the Harbes family loves food and wine, it also devotes a large portion of time to environmental preservation. The farmers use locally sourced compost to reduce to need for commercial fertilizer, and as of 2012, they have placed more than 50 acres into conservation easement, ensuring that the land is never developed or used to grow an army of giant brussels sprouts.
