Do ants get drunk?

 Walked part of the college Nature Trail the other day after many months away from it.  At first, it seemed the Gooseberry season was over.  Most of the bushes I saw had dropped their berries, or the few remaining were in various stages of shriveled up.  Then I saw the one above that was somehow photogenic.  I figured there was a lot of fermentation going on inside.  Then I saw some ants crawling up the branch toward the berry.  I didn't stick around long enough to see the rest of the story, but I wondered.

 A little further down the trail, probably in a different microclimate, I came across some bushes with fresh berries.  They were a welcome snack, after taking a few pictures.
