Stouts

By saying 'my batches' are you referring to your homebrew?

I think we have to deal in generalities here, but it seems like most of the beers where minimal carbonation is experienced are dark beers, although I'm going to guess from my experience that most dark beers do have a reasonably normal amount. If you are experiencing low carbonation where you don't expect it, then any soap residue that is left over from washing your glass should be a factor to consider.

 

No. This is not correct.

Need more information but low carbonation is not a function of style.

And "light" or "dark" have little to do with it.

 

I'm a little confused. Are you talking about homebrew stouts or purchased stouts? Neither should necessarily have really low carbonation, but the reasons that your's might depends on what the beer is.

 

Carbonation depends on how much priming sugar you used (if bottling) or on how many PSIs you're forcing CO2 with (if kegging). There's nothing inherent in a stout that keeps it from being able to get high cabonation levels, if that's what you want.

 

Stouts are generally medium when it comes to carbonation, although it's quite a range from med/low to medium high. You don't normally see the carbonation in anything dark...other than the accompanying head... and stouts are rarely highly carbonated like some other paler styles...which might lead to the perception of low carbonation.

NOT!

I didn't carbonate my stouts much differently than I did any of my other beers, and they came out fine. I haven't brewed a lot of them (about to brew another one tho). If I am going to brew a stout, I want the carbonation to be ample when I do. I don't like under-carbonated beer. A little extra won't hurt, especially if you drink them fast (mine don't last long once finished).
