Rapid and redstone in stoneham had it this past week. maybe wednesday? Both limited to 2 cans of oscillation, pp. (i think)
I grabbed a couple at Redstone in Andover Thursday. They were the last two unless there were more in the back.
I bought a 4-pack of the Oscillation 003 at the Craft Beer Cellar in Winchester. I don't know much about finback, but I was impressed and would definitely buy it again. But, given the name I'm guessing Oscillation is a bit like Morph in that they tweak the recipe each time?
I thought Oscillation 003 was fantastic; reminded me a bit of the Treehouse "soft" mouthfeel, really good stuff. Would buy more if I could find it!
