Many people have asked me why homebrew has such a gaseous effect on some folks. I did some research. Part of my research I uncovered the following thread which I am reprinting from www.tastybrew.com
Beer Farts Prevention by Jason
My SWMBO is generally very supported of my brewing and subsequent consumption however she does not appreciate the after effects...the HomeBrew fart. She tells me that she refuses to go to the bathroom at night becuase she fears the return trip (fresh air-> contaminated air). I dont really have gas problmes with commercial beers or any foods but man when I drink HB look out! Is this a common symptom? Is there anything that can be done to minimize it or prevent it? I bottle all my beer and I am generally very careful about leaving the sediment behind but you always get some. I assume that the largest contributer to the problem comes from the yeast.

Jason,
You should do what I do, drink enough to crap your pants- she'll never complain about the farts again.
Response by Tom C.
The anti-flatulent product "bean-o" is actually enzymes that were originally developed for use by big brewing companies, and works by breaking down complex sugars (polysaccharides) into simple sugars that humans can digest. Complex sugars kind of go right through your gut, and feed your flora in your large intestine and colon.
You can brew low-fart beer by not having a lot of dextrins and/or residual sugars in your beer, or by staying away from styles that end sweet and dextrinous (like lots of English ales).
Speaking of which: there was a story in Fark.com recently about a pub in England that lately banned smoking, only to discover that one of their most reliable patrons was a regular gas plant. They decided to ban him.

Tony: I'd be scared to see how much it drink it would take to crap your pants, and more to the point, the quality of beer that would make one "crap your pants." But you are thinking, so thats something.
Response by A. Vicenzi
Quality really has no effect, just quantity
Response by Burp
I too have this problem. Gasp, I can't believe I admitted it. I'm also lactose intolerant. I have some beano and I may try a pill before I consume homebrew.
Response by Greg
Homebrew has the opposite affect on me... I generally rip em with just about anything I consume.. Scared a pack of dogs off a meat wagon once.. but I like it like that....
No beano for me!
Response by BeerCzar
My 'friend' also suffers from this issue most notably within the hour of the alarm going off or so I heard his' wife' say..... So when should I suggest 'he' add the beano...?
Response by Rob Hudson
Dear Reader, I have't posted for a few days, i have been doing alot of research, many hours infact, the homebrew fart figures that Jason are way way out, Tom C figures for the beano are not too far out(but still the wrong gasses), i have built a fart ripper and it break all the figures that anyone has come up with. All i can say in this question and time is the flatulance is hell of a percentage more than every ones 10%.

Jason,
Don't fight the farts...
Get the SWMBO to have a brew with you. Then, she won't complain later, since you would both be prime suspects when you feel that summer wind.
Either that, or switch to brewing Beano-bock.
Response by Bob G.
Just feed her some beans and tell her the farting lamp is lit and all will be well in stinkiville
Response by Roy S.
Actually, when I was a kid, my grandfather used to ask me to bring him a beer. Then, he'd ask me to pull his finger.
I always figured beer farts were just another part of the process.
Response by Greg
Beer! Beer! Its good for the heart, the more you drink the more you fart, the more you fart, the better you feel, so drink more beer ya big ol'schmeel.
Amazing what a little research can find out there. If you have any bright ideas, post them as a response to this blog post and I will pass them along to the boys and their wives.
Followup:
This blog post has provoked a tremendous amount of conjecture regarding the true origins of the beer fart. I decided yesterday to ask the experts. I asked Rob Arbagey store manager for B3 in Riverside the scoop... Rob said it could be one of two things. "It could be the maltodextrin reacting to someones system, or it could be yeast left in suspension in the beer that ends up in the intestines attacking whatever it can find in there and creating the gas." Sounds reasonable to me Rob... We still don't have the solution, but we are getting closer to understanding what is going on... when we do, hopefully someone will come up with the cure.
