Does anybody know how to make a brew from topinambours aka sunchokes aka 'jerusalem artichokes' (silly name) - that's all i've got too many of at this time of year ?

Not sure about the how, but it appears that in Germany they make some sort of spirit out of them. So they can be fermented at least.

If you usually ferment beer I'd try and substitute some (boiled or baked and mashed) for part of the grain. Just remember that they're like 18% carbs or so, so you'll need quite a lot. And don't forget the rice hulls, to prevent a stuck mash.

Wikipedia also says that when they're stored, inulin converts into fructose, so if you have some lying around from last season maybe try those first.

In my childhood, we had these kinds of root vegetables sliced and caved in on one end, and a spoonful of honey was placed on top and in the cavity. Somehow this sped up conversion to overnight, and it was a treat. I guess, similar process could be used to convert them for brewing.

Although the whole idea sounds a bit like potato for vodka. Nothing wrong with that too, but the flavor might me less than interesting in the end. Worth trying I guess. I wish I had some of those now, not unripe ones from the store.
