Default Carbonation question

I am brewing 4.25 Gallons of Northern Brown Ale from extract. I have found that my past few brews have been WAY over carbonated for my liking when i use 3/4 of a cup of corn sugar for 5 gallons to carbonate. Due to the smaller size of this batch would i be way off to only use 1/4 or 1/3 of a cup to carb this batch? Thoughts questions comments...

Two things to try:

1. Scale 3/4 cup per 5 gallons down to the amount in your primary (4.25 gallons would be about 2/3 cup, exactly .6375)
2. Make sure your beer is done fermenting. A lot of overcarbonation can occur when the beer has not yet finished when you bottle.


Fermenting: ESB
Kegged: Extra IPA, Brown Ale, American Wheat, Blackheart Stout
Coming Up: Dunkleweizen, 3C Pale Ale

Best thing to do would be to measure your priming sugar by weight and use a software tool to calculate exactly what carbonation level you want for that particular style of beer.

That one'll work, but I've seen better ones out there.

The style says 2.0-2.6 volumes.Try using 2.3 oz corn sugar for 4.25Gal and 2.0 Volumes. Which is just over 1/4 cup corn sugar

They usually supply you with 4 oz of CS for priming.

4 / 5 gals = .8 oz per gal of beer...

Never use the cup method because CS can compact. Once it does you've inadvertantly overprimed. On the other hand if it's not compacted are you underpriming?

I recommend weight...
