That's the trade off. The further you get from a long aged starter, the closer you get to a plain rye flour loaf.
Our starter is pretty stiff and after about 6-8 hours we get a good flavour from it. We don't fridge ferment though. Might do if we do the sourdough version.
So for anything with rye, long cold fermentation is key? Or just long?
I ferment my rye for 3-4 hours at room temp and get good results (see recipe upthread) but as with all fermentation generally the longer you go the more complex flavours you tend to get developing.
