Yes, it’s a bit off topic, but I want to put this somewhere and this seems as good a place as any.
If you like beer, but wonder what the difference is between one style and another, here is a handy poster for you. This poster gives a quick at-a-glance comparison of the various styles as described in the 2008 Beer Judge Certification Program Style Guidelines (an updated set of guidelines is also available, but it doesn’t correspond with this chart). The beer style information you can quickly compare here includes color, flavor, aroma, appearance, and mouthfeel. See the written version of the guidelines for more detailed information.
