Since I had some trouble finding details about the legendary Walker Apples outside of Sebastopol, I thought I'd report back on my adventure today.
Walker Apples sells over 25 varieties of apples over the course of the season. They're located about 6 miles outside of Sebastopol, and Google maps has no problems finding it. You go through the village of Graton (which appears to basically consist of the polenta place), and to the signed turn onto Upp road, which rapidly disintegrates into a one-lane unpaved track. Once you've gone past the point where you start to feel lost, you come to the farm, drive past the house and out to the packing shed. (there are periodic signs once you make the turn onto Upp road).
Once I found it, they were tremendously friendly and gracious. The current varieties are stacked in boxes, and they cut samples of each of the varieties for me (with a couple of dogs waiting for the occasional treat). Once I tried everything, she explained the pricing - $1 a pound, $14 for a half bushel box (approx 20 pounds), $22 for a full bushel (approx 40 pounds). The only exception was for a full box of pink lady apples, which was slightly more expensive. I decided to go with a half bushel, and was handed a box to fill with my choice of apples. Once I thought it was full, I was encouraged to add more and more - I actually stopped before they considered it full.
She gave me a brochure the showed the list of varieties with approximate timing:
July - August: Gravenstein, MacIntosh
Early Sept: Macintosh, Red Gold, Empire, Red Delicious, Greening, Bellflower, Golden Delicious, Winter Banana, Jonathan.
Mid September: Northern Spy, Baldwin, York Imperial, Winesap
Early October: Granny Smith, Rome Beauty
Mid October: Ben Davis, Arkansas Black, Ortley, Pippen, Winter Permain, Wagner, Pink Lady
This made a great mid-October adventure. They're open until November 15th, and I definitely recommend this as a destination.
