Dark Wort -crazy Fermentation

[mikem108]

I've noticed this happen to other peoples beer and its happened to me both times I've brewed a beer like this.
My question is why do Stouts and Porters have more chance of climbing out of the airlock than other beers?

It is directly proportional to their ability to leave stains.

Water, white wine and pale beer are rarely spilt. Red wine and dark beers are inherently acrobatic and require more room to move.

that's it, problem solved, that's why the Russian Imp Stout is spilt and others are not, nothing to do with being close to 10%.

I have a Belgian Wit crawling out the fermenter so the above rule does not apply to all pale beers. <_<

I think it might have something to do with the extra sugars and caramels etc (larger stickier ones that give the flavour colour to dark beers) in the wort giving it an extra 'foaminess / foamabilitty' (for the lack of a better word)

Happened to me too. With wheat beers too. AFAIK, it's due to the higher protein content of wheat, flaked barleya and roast barley. Also for stouts, the higher viscosity helps head retention/krausen. This article may (or may not) make things clearer.

Then again, wortgames has a very convincing argument.

Yes very simular to that the airlock looked like it had softserve choc icecream coming out of it, $#!& was everywhere !
Had calmed down by 6pm so I put a fresh lid and airlock onto it, back to normal bubling, could have had something to do with the 24 gm mega-sachet of Nottingham from Ross that I dropped in there!
