I may not have had a very good example, but as soon as I tasted the Aecht Schlenkerla Marzen rauchbier, all I could think of was bacon. Too much bacon (if there is such a thing). My friends and I couldn't finish the tasters we had, and we're fairly openminded when it comes to beer.
However, it got me thinking. What if this was used to marinate a pork loin? Obviously I've made pork loin wrapped in bacon before (more to keep it moist than to really impart smokiness), but this beer made me think of bacon in a bottle. I live in an apartment, so actually smoking something is out of the question, but marinating for a day in this beer might have a similar effect. Anyone tried this before? How did it turn out?
