Turns out they make a few single varietal ciders from Discovery apples, as well as several blends that focus on Discovery, Gravenstein, and James Grieve. These get good reviews and seem to be quite popular. It is recommended to use wild yeast for the best result, and brewers report the process can take up to 6 months PLUS a year to condition in the cellar. They say cider made with added yeast like M02 is very good but loses the unique character of the varieties.
Discovery, Aroma, Summerred, and Gravenstein are said to be particularly suited to the climate here, which is similar to that of the Pacific Northwest up through the coastal parts of Canada and Alaska. Not sure how many guys here are in those areas, but if anyone up there is interested, they also grow plums and sweet cherries, so I can get info on those as well. I didn't see a single pear tree, though pear cider is quite popular here.
Another note is that the "yellow" Gravenstein is favored over the "red" Gravenstein here for juice/cider.
