Re-priming

[Fishybrewer]

I have a batch that has come in under-carbed and does any one have a remedy for this. It was 3 weeks fermenting and 4 weeks bottled at 68 degrees. My first thought was to wait 2 more weeks and try again. On the Mr Beer site someone posted a thread about this several years ago, but that's a waste of time now, as you can't find anything anymore. I f I remember correctly, it used an eyedropper and sugar solution to re-carb but not sure of the details. Thanks David

It's tricky. If you add sugar to the bottle, it can immediately start overflowing. My suggestion would be to both wait two more weeks AND see if you can bump the temp up a few degrees.

I believe I remember seeing that thread. Someone had dissolved sugar in boiling water, chilled it, then add a little to each bottle with an eye dropper, with success.

Rick is right that just adding raw sugar can/will cause overflowing due to all the nucleation sites added to the beer.

If waiting as Rick and Inkleg mentioned does not seem to work, I successfully reprimed an undercarbed Witty Monk last year, following the thread on the old MrB forum, http://community.mrbeer.com/community/d ... ed-bottles

i used a ratio of 1/2 tsp of sugar per 12 oz bottle when i reprimed. i gathered enough sugar for all bottles (11 bottles=5.5tsp) and added a very small amount of water to it, just enough to dissolve and boil in microwave (about 90 sec?). once cooled, i used a sanitized baby medicine dropper to measure total sugar solution in ml's. divided the total ml by 11 and that gave me the amount of solution to add to each bottle. recap and turn bottles to mix. dissolved sugar is much much much less volital when added to partially carbed beer than granulated sugar. and the volume added was minimal.

Thanks Sparrow for finding that link. I had this same problem and tried many different methods and was glad to be able to share the experiences so others could learn from it. I hope the information helps you.

That's the 1. Thanks Sparrow, I will wait 2 weeks and try that. Actually I did it after that thread and it worked great. The mystery is why it happened. Thanks David

Luckily my Googling skills are better than my brewing skills Hope it works out for you again.
