Another vote for Domaine Drouhin -- and check out Domaine Serene across the road as well. The Dundee Hills area in general is just amazing. On the complete opposite end of the spectrum, check out the tiny winery called Hauer of the Dauen -- it's a local farmer who turned his fields over to vines and is usually there in person. Great to get that personal touch after the bigger wineries. Plus, some amazing late harvest wines for even more amazing prices.
