Of course, you’ll be deep in Wine Country there, and I should encourage you to stop in at one of the bajillion wineries for a drop of pinot — it is definitely worth a stop. As for beer, a couple to put on your list are Golden Valley (McMinnville), one of Oregon’s older breweries and a good one. The long-time brewer there, Mark Vickery, went off and started Grain Station (McMinnville), which should probably be your first stop. Great story, great place — and great beer. Another brewery I love is Heater Allen (also McMinnville), but they focus on lagers so you’ll have to decide whether that fits the bill. (Lagers have finally started to get popular in Oregon, and this brewery is one of the big reasons why.)
A couple other places to note: You might consider driving to Salem to check out Santiam, which is an interesting brewery that does mainly cask ales. It’s unusual and you might find it interesting. There’s also a new brewery in Dundee called Deception. Breweries open so fast in Oregon that I’m falling behind. I still haven’t made it out there. Perhaps you can go and tell me what it’s like.
