I'm curious about the same thing, and hope there is someone around who has tried both. In the meantime, have you tried BB's Cafe Latte? It doesn't seem quite as "deep" as Espresso but has the advantage of not discoloring much at all! I saw a soapmaker on Instagram a few years ago who made a bar with layers of the different BB coffee & cafe scents, and the Cafe Latte she put on top was quite light (maybe with TD, don't know). Might be nice to blend with just a little Dark Roast Coffee (which has a note of hazelnut that doesn't appeal to me*) or perhaps a chocolate...
But would love to know your verdict about the Midwest Espresso, should you decide to try it!
*just because I don't care for nutty scents in general, and very much dislike hazelnut flavoring in coffee
