  • @roxtar10870 That's not true at all. There isn't enough alcohol in beer during krausen to kill 90% of airborne pathogens. Even once the beer is completely fermented out at, say 6%ABV, there's still residual sugars and nutrients for wild yeast and bacteria. Why do you think you have to sanitize bottles/kegs before bottling/kegging? And yes, there are strains of harmful bacteria that can survive in fully fermented beer, infect it, and harm you if you drink enough of it. Brewing microbio 101.

  • For sure.  Using a fermenter with a gallon or a gallon and a half more space than your total batch of wort should do the trick. Point being, don't ferment (primary) in a 5 gallon carboy!

  • @ethans83 NO there is nothing that can harm humans, the worst thing that can happen to your beer is a little bit of acetic acid bacteria. even then its not a wast , at least you will have some malt vinegar!

  • This is what happens with too little head space.

  • the froth coming out of the beer bottle remind me of somthing else coming out of somthing else

  • You should never fill carboys into the neck of the bottle. It will almost surely result in a spill unless you have a blowoff tube.

  • @sadeghsafari100 Whatever makes your beer bottle pop, mate.

  • thumb nail is like erected dick..!!

  • remove the airlock, it might blow.. replace it with a blow off.

  • @crazedxfighter Johann Sebastian Bach ftw!

  • @skatekai If the penis has syphilis! xD

  • Am I the only one thinking it looks like a penis?
