We stopped by in late September and we were pleased but not wowed by this winery. The standout of the tasting was the Meadow Road Wheat Beer. It was quite good, smooth and flavorful. The rest of the wines and beers were decent to good but none stood out so much I remember them. The tasting room has a nice feel to it with lots of wine paraphernalia for sale.
One comment I will make about the tasting: it was the most costly of all the tastings we had in Maine. We visited 5 wineries in Maine. Three were free to taste up to 6 different vintages; one was $2.50 per person for a choice of 6 and also sent you home with your tasting glass. Winertport Winery was $3.00 per person for a choice of 6 tastes of the beer and wine. Considering that they have 25 different beverages to choose from, it means that if you were really interested in tasting most of them, it could cost you $12. While not a huge cost, it is high by comparison to the other vineyards in the area.
Still, if I was in this area and in the mood to go to a vineyard or brewery, I would give this place a shot.
