Heat oven to 425 degrees.
Season chicken on both sides with salt and pepper.
Heat 1 tablespoon oil in a large skillet over medium-high, and add chicken, skin-side down.
Cook, without flipping, until the skin is deeply golden and much of the fat has rendered, 8 to 10 minutes.
(You may need to pour off some of the fat.)
Using tongs, flip the chicken skin-side up.
Let the undersides cook for another 5 or so minutes.
Set chicken aside.
Add artichoke hearts and onions to the pan, letting them sizzle until they get a little color, 3 to 4 minutes.
Add the Somerset Ridge Chardonnel Wine and thyme, shaking skillet to make sure the wine is evenly distributed and scraping up any golden-brown bits.
Add chicken back to the pan, over the artichoke hearts and onions.
Bring to a simmer and place in the oven until chicken has
finished cooking and sauce is reduced by about half, 10 to 12 minutes.
Remove chicken from oven and scatter with herbs.
Finish with more pepper, a drizzle of olive oil, and a sprinkle of sumac, if you have it.
