A little birdy told me...
Or rather, Isaac, from New Holland Brewery;
Told me last night at the Brewer's Night at Crunchy's in East Lansing, that New Holland is working on producing for sale bottles of their Oak Aged Mad Hatter. Mad Hatter is New Holland's famous IPA. And once they oak-age it, it gets this wonderful flavor much like whiskey. Whiskey and beer? Now that's a famous combination!
Due to limited brewing area and limited space to store oak casks, their batches for bottles will be smaller than their usual batches for, say, Sundog ale, their also-famous ale.
Haven't tried New Holland beer yet? I highly recommend it. All of their beers taste very clean and polished. I have never been disappointed!
