Aliasing sake_serving_bottle -> tokkuri
Reason: Same thing.
tokkuri -> sake
tokkuri -> bottle
There is also a sake_bottle tag, but this seems to have a mix of bottle sizes, including larger bottles as well. Personally I think this tag is not useful -- it is equivalent to a search for sake bottle (two tags). To get only large sake bottles one could use sake bottle -tokkuri. Thus this tag does not help to provide any distinction between bottle types and should be treated as ambiguous if not nuked after posts are re-tagged appropriately.
