I brewed a standard porter about a month ago and added ½ a bottle of Jim Beam, 8 oz of cocoa nibs and 2 vanilla beans a week ago to the secondary and now it is re-fermenting.  I have bubbles in the S airlock every 2 -3 minutes.  Not sure if this is normal and if it is how long it will take to stop.

It is not refermenting, because you haven't added anything much that is fermentable.

Bubbles are not a good indicator of fermentation activity anyway, and one every 2-3 minutes is meaningless.  That is more likely to be the effect of the beer cooling off at night and heating up during the day.

If it has been sitting for a month it is as done as it will get.  Taste it daily to see if the vanilla/cocoa flavor is where you want it, then package the beer.

I agree.

I did a beer much like this a while ago and found that it would bubble for a bit any time I would add something to it. But just because I would move the fermenter around a bit, as well as what tschmidlin said... temperature changes can do the same.

Sounds like quite a flavor bomb. I bet its gonna be great! I always find beers like that to take quite well to aging. As the flavors blend together... its a beautiful thing.

That's a LOT of Beam!

What's it tasting like?

I agree but it really depends on the definition of "bottle".  Half of a 1/5 would be a lot.  Half of a pocket bottle, not so much.

If I'm not mistaken, Denny's BVIP calls for about a half of a fifth.

It does seem like a lot of bourbon, but it's going into 5 gallons.

I added 375 ml (1/2 a fifth) to my bourbon porter per Denny's recipe and have been really happy with the results.

Yep, it's not as overwhelming as it sounds like.
