Cypressbob, you've listed Drie Fontenien oude gueuze on your favourites list, also one of mine. When I was in Belgium earlier this year I visited the brewery restaurant and got to meet the brewer himself, Armand. It was completey by chance really. He was meeting two brewers from Russian River Brewery (US) and we all got talking over rabbit and pheasant gueuze stew. He invited us all to his warehouse so we all bailed into his Merc and off we went, half-cut of course!!
The lambic he sells are blends of other breweries gueuze and we got to sample some of these in their unblended forms, all very interesting and quite complex in themselves but blending them together is Armands real skill. As you know yourselve, his gueuze is fantastic.
I'd love to source it in Ireland. Have you seen it anywhere?
