Carb issues

[LoopeyLoon]

So I've always and some carbing issues with my beers, and till I can afford a keg setup I'm SOL. So lately my issue is under carbing. I use beer smith for how much priming sugar to use. And my beer sits in a spare bedroom so it's not overly cold 67-70 is the room temp. But I sanitize my bottles in the dishwasher , I don't add soap just rinse and high temp dry. But could the residual soap left in there be killing the carbonation when bottling?

I also wash all my bottles in my dishwasher with soap before sanitizing and bottling. I have not yet had an issue with under carbonation. How long do you bottle condition? What yeast are you using and do you make a starter for fermenting?

 

[LoopeyLoon]

No starter, and usually I use wyeast 99% of the time. And I usually wait 2 weeks before trying any beer. Before I never had an issue but now I have. Just trying to figure this out. My next batch I may just sanitize bottles with star San and see what happens. Anyone have a better idea?

Are you talking about carb level of the beer or head retention of the beer? Soap can reduce head retention but will not impact how much co2 is actually dissolved in the beer.

You can have a perfectly carbed beer with absolutely no head on it.

What's your brew process?

 

[rawlus]

Dishwasher soap often has bubble killers (rinse agents) like dawn, jet dry, finish or other surfactants.

If this is the first time you have experienced a lack of carbonation, then there has to be an underlying issue. Did you wash bottles in your dishwasher before for other batches?

 

[LoopeyLoon]

Yes I have always done this. But last 3 or so batches have posses issues.

We just started using jet dry for our hard water issues. This could be the bastard.

After the dishwasher, you can rinse the bottles out with hot water to get rid of much of the rinse agent. Modern dishwasher have a reservoir of the stuff, so it matters not that you leave out the detergent.

How many ounces (by weight) of sugar are you typically using for a 5-gallon batch?

 

[rawlus]

Run the dishwasher with PBW instead if a dishwasher detergent, just throw a small scoop of PBW in the bottom of the dishwasher.

This has the added benefit of cleaning the dishwasher itself.

When you say you're using a priming calculator, how much priming sugar are you using? You need about 4 ounces of corn sugar for 5 gallons of beer to get a medium carbonation level, regardless of what the calculators say.

 

[LoopeyLoon]

I'm in the neighborhood of 4 oz to start with.

I had the same issue until I listened to a Co worker of what he does.. Which is take your beer out of primary or secondary into bottle bucket. then add your corn sugar or dme. Then stir for a good five or so minutes let sit for ten minutes. Next bottle away. This works for me.
