Hi, I'm making my first brew, using Brooklyn Brew Shop's Chestnut Brown Ale gallon kit. After 24 hours of bubbling in the fermentation bottle, I now see almost no activity at all.

I "modified" the brew by adding 15oz of canned pumpkin before boiling. Also, my basement is a bit cool, 65 deg.

Should I add more yeast or did I screw things up?

Thanks for any comments!
Ralph

What's the gravity? That's the only way to really tell what the yeast are doing / have done. 65F is a perfect temp, though the beer itself will be a few degrees higher inside than the room temperature.

It doesn't mean anything that the airlock stopped bubbling, except there's no need for it to bubble. It's a vent, to release excess co2, it's not a magic fermentation gauge. Whether it stopped or starts again means nothing.

You don't have to re-yeast, you just have to stop hovering around your fermenter, and let the yeast do what they need to do. Read this and walk away from your fermenter for a week or 3.

15 oz of pumpkin in a 1 gallon kit seems like a lot of pumpkin.

Follow Revvy's advise, fermentation performs quite nicely without human intervention.

I bet Revvy has a script written that searches for "bubble" every 5 seconds and alerts him if there is a match so that he can respond.

I know this thread is (except for the pumpkin) covered in numerous earlier posts, but there's *beer* at stake!

So it came out fine of course. Though I didn't crack the secret of a really good pumpkin ale, it is not bad.

I just started my second effort, again using the Brooklyn Brew Shop 1-gallon grain kit -- this time a Chocolate Maple Porter.

This time there's still plenty of bubble activity at 5 days after starting fermentation. I'm guessing the difference is that the temperature of my basement is lower (62-64 F versus 68-70 F for the previous effort) so the yeast are taking their time. Also this recipe called for adding 3/4 cup of maple syrup to wort, which is a lot of additional fermentable sugar.

The following is a humorous response and is not to be taken seriously

But... on the DIY forums there's a really cool project for building a computer controlled bubble counter. It logs the time of day, how many bubbles were released, and estimates total co2 released...
