In this economy, and if I were the owner of either De Laurenti's or Pike & Western, I would definitely bring in higher profit booze. I would especially bring it in to due to the high tourist volume.
If 1100 passes you can say good-bye to roughly 30-40% of the floor space in your favorite wine shop to hard liquor. This means that 2 out 5 of your favorite wines will probably be no longer available at your store. And this will occur across all stores. So unless you're drinking the high volume wine (two-buck-chuck) or the big profit wine (DRC) this will have an impact on your wine purchases. If it's a choice between a $6 profit on some 'cult' Oregon Pinot Noir or $20 profit on some random vodka, it's a no brainer to the store owner.
I just don't see this happening. De Laurenti's and Pike & Western are going to give over huge floor space to boooze? Why would they when they've cultivated a clientele that shops there for interesting wines? I see your point, but would they rather sell a single bottle of vodka or a mixed case to a long-time customer? Wine shops are going to be wine shops. Will small wineries lose shelf space in grocery stores? Probably, but that's been shrinking with the economy anyways.
I don't think the small wineries have that much presence in grocery stores. And I'm not as concerned with how 1100/1105 would affect grocery stores because of the small space they currently have for wine/beer compared to their total square footage. They can knock out half an aisle of cards, wrapping paper, and balloons and relegate it to an end cap with no loss of that business and not affect their wine/beer inventory.
Based on my experience shopping for elusive (to WA) booze in California - the stuff that I am looking for is usually found at the specialty wineries. But, except for one or two of the most popular spots, it's found behind the counter - taking up a small linear footage. But I see what you are saying.
