BM-45 is a wine strain. It's been around for a while. Used to be (or still is) a Lallemand strain but it's not super easy to find anymore. It doesn't come in the typical Lallamand homebrewer-sized packets. Not sure who packaged it, but I got it at Midwest.
I've got a Belgian dark strong fermenting with BM-45 and B. lambicus right now. The hydro samples are a full-on cherry assault on my nose. I think a split ferment, maybe half and half and blending to taste would be the way I'd go if I wanted a balanced cherry flavor/aroma.
It's a slow starter and has high nitrogen needs, so it's kind of crap for a wine yeast, but does pretty well in wort once it picks up speed.
