Preheat stove to 375 degrees. Spread a shallow 2-quart dish. Cover potatoes with water in a medium pot and heat to the point of boiling. Season with salt; cook until potatoes are delicate, around 10 minutes. Channel.
In the mean time, cook bacon in a huge skillet over medium intensity, turning, until fresh and brilliant, around 12 minutes. Move to a plate; pour off everything except 1 tablespoon fat from skillet. Add onion; cook over medium intensity, blending periodically, until softly caramelized, around 15 minutes. Add wine and cook until diminished, around 2 minutes. Mix in bacon.
Orchestrate half of potatoes in pre-arranged dish. Season with salt and pepper. Top with half of bacon blend and a big part of cheddar. Rehash with outstanding fixings. Heat until cheddar is rising, around 25 minutes; serve.
