A Store With A Big HistoryThe building that houses Sunny Slope Winery has been standing since 1927. The General Store Side Of ThingsBeyond the deli counter, Sunny Slope Winery doubles as a proper general store. The interior layout manages to feel open enough for families without losing the cozy character that makes Sunny Slope Winery so appealing.

On a warm afternoon, sitting outside at Sunny Slope Winery with one of those mason jar slushies is hard to beat.
