Not sure about this year, but I do not recall seeing it in 6-packs last year. The Clybourn brewpub had a selection available in 22oz. bottles (great stocking stuffers), but they didn't last too long.
I have seen their Mild Winter ale in 6-packs lately. I haven't tried it this year, but from their website:
Mild Winter Ale 5.6%ABV
This seasonal release is a tawny red rye ale. Made with a variety of specialty malts including roast barley and rye, this beer is a caramel forward, very slightly spicy ale that has a slight hop aroma from the noble aroma (Pilgrim, Willamette and Tettnang) hops. Served in a Pint glass.
Sounds pretty good, too!
best,
