I guess this is a question I'm rather qualified to answer, as the Iowa rep for the importer. Vague commercial interest alert.
The Fantome beers are worth the effort. They can be, on ocassion, wildly inconsistent, but the reward is quite high. We get precious little of the beer, and at quite inconsistent intervals. When it's good, though, it can be some of the best artisinal farmhouse beer in the world. We recently got a decent sized Fantome shipment, so what's on shelves should be more or less pretty fresh.
The brewer, Dany Prignon, founded the brewery more or less to create another local product for the regional tourist board (which he worked for, and afaik, still does) Dany will brew using a myriad of local and obscure (and not so obscure) herbs and spices. Dany insists that his beers are not really for aging, but I've had good luck with some beers in the 2-3 year range, and I've got some really old, (10 years?) hanging int the back of my cellar.
Where are you located, Scott? We probably have some local distribution where you're at. I can probably suggest a retail location not too far away. If not, one good location to buy these online is:
It looks like they have 4 Fantome beers in stock, (they're in the belgian ale section)
If you're looking to fill up a case for ordering I've got all kinds of suggestions as for other things to try. There's lots of great Hoppy American stuff (Russian River, FTW!) and Belgian/European stuff (Orval!, Dupont Avec Les Bons Voeux, no commercial interest there, just fantastic beer) as well as other Shelton Brothers beer I'm rather big on, Haandbryggeriet and Nogne O (Norwegian) and Mikkeller (Danish), and Thiriez (northern France)a personal favorite of mine.
If your clamoring for more let me know, I'll happily blather on...
Cheers,
Kevin
