I have been trying to learn from Fish (my best friend Forrest's dad) for over 15yrs now, working on the vineyard a couple times a year even though I live 6hrs away. He had the foresight to plant Pinot and 12 other varietals in the Willamette Valley within five yrs of the first in the area, almost 40yrs ago at this point. I helped Forrest plant a couple more acres starting about ten years ago. Now we are transitioning an overgrown orchard into suntraps that also function as arbor/trellises. Harvest is a true joy, and I
think the grapes reflect the flavors of the
compost tea made naturally in the fallen stonefruit and tree detritus above the vineyard.
l digress...in terms of the happy lemon in Seattle, beyond good ol farmer magic I would attribute its success to being about 2/3 of the way up a SE facing hill with a house above it to the NW. The bottom of the hill has a grocery store parking lot and large arterial covered in black top, and this undoubtedly radiates heat. It also probably likes the boner view of Mt. Rainier.
