And whats the recipe?
Is it a RIS?
Preaching to the converted.....
Science...
thing about using glad wrap as a seal is that it's mainly to prevent airborne particles from entering the wort, u-know, flies and dust and things that float around like fungus spores...
"Air" is a mixture of various gases - mainly Nitrogen (80%) the rest is mainly Oxygen with small amounts of all the other gases known to exist, including our friend - Carbon Dioxide CO2...
Now - whether you use an airlock or not, there will ALWAYS be some AIR inside the brewbin - true, the amount of air gets less and less as the brew proceeds... but not drastically so...
The OXYGEN in the air is what causes the brew to OXIDISE...
The brewing process produces CO2...
Since CO2 is heavier than AIR it forms a layer directly above the surface of the brew - the AIR floats on top of the CO2 layer, preventing the contact of oxygen with the brew - preventing oxidisation...
It's the LAYER of CO2 that protects your brew from oxidisation...
The Gladwrap or (Lid with airlock) or double-folded tea-towel helps to keep air-borne foreign bodies out...
Just my tuppence-worth...

Hey Tipsy, that mess is the ever popular 2can stout, as follows:
1 can Coopers stout
1 can Coopers Dark ale
100 gm dry wheat malt
20 gm Goldings pellets
I brew this 2 or 3 times a year and its pretty vigorous, but I've never before had one go off like this. Three times I replaced the Gladwrap and washed down the outside before it calmed down! And it was pitched and brewed at about 21C, a lot cooler than I generally do this one. I was wondering if Coopers has put out a new and even more virulent strain of yeast. At least it adds some excitement to brewing, as well as giving the dear little wife a chance to howl about "that disgusting mess in the bathroom"
