I had a butternut squash beer the other night that had some discernible squash flavor, that sweet-like nutty thing. but it's mild.
I'd like to try that, if you'll share your recipe. We grow a ton of squash too. One variety that is really nice (productive and much like butternut) is Jumbo Pink Banana. I originally ordered it as kind of a dirty joke on my wife.
But they've been really great. The flavor intensifies as they age and lose some water. We usually eat the butternut first and age the JPBs. By the time the butternut are gone the JPBs are excellent. We're just now cracking into the stash of JPBs. They're pretty amazing - some are almost the size of my upper leg. Like a giant football.
