Bigfoot is definitely a very visible example at most bottle shops, but I have also had Dogfish Head's Olde School Barleywine and found it to be eminently sippable.
Bigfoot nowhere to be found, or any other barleywine.
Checked Sierra Nevada's website, they start making Bigfoot in January.
Will buy a 6 pack, put in basement, drink one every Christmas.
How did Lutra work out for you ?
