We have a tag, specialty-beers, which seems to be quite the hodge-podge:
Questions about special ingredients or processes: Do kosher beers exist?, What are some of the most common ingredients used in gluten-free beers?, Other Jalapeño beers?, Beer with honey, beer with cinnamon
Questions that don't seem to be specific to specialty beers: Beer Clubs Online, Eat bread before drink beer make you drunk less?, How to chill a 30cl bottle to "cellar" temperature?, Who made commercialization of beer possible, Beer-A-Day (Free Online) Calendars
There are more; I'm not trying to catalogue the entire tag here.
We probably need to retag some of these, and maybe we should be creating other tags. We already have trappist and hefeweisen, for example; I'm surprised we don't yet have "belgian". I think there is a place for a "specialty-beers" tag, but the current state of the tag seems wrong.
What should this tag be about? (It has no wiki now.) Do we need additional tags in this space? Which ones?
