I've got a 1 litre starter fermenting with wyeast forbidden fruit yeast and
I have noticed a slight rotten egg smell at the airlock, is this normal or
is the wort infected?

Re: rotten eggs smell
Yeah, it's a Belgian ale yeast, I threw the packet out so I don't have the
number.

Re: rotten eggs smell

The book "Mastering Homebrew: The Beer Maker's Bible"
by Brian Kunath (ISBN 1-85076-991-5) says of "Sulfry,
rotten eggs":

   "Hydrogen Sulfide is often formed in small, unnoticeable
    quantities. Bacterial infection is usually to blame for
    excessive (noticeable!) amounts."

The cure is to "Maintain sanitation and fermentation temperatures."

Some Belgian type yeast give a rotten egg smell during fermentation and the
smell goes away after fermentation is over. So i would sugest to relax and
wait a while and check it out when you transfer to secondary. If
fermentation is over and the smell remains, it's probably an infection.
Otherwhise you will be Ok.

Re: rotten eggs smell
I wouldn't worry. Some yeasts will produce a bad stench during initial
fermentation. A starter should be no exception.

I remember a Kolsch I made which stunk like egg farts when the yeast kicked
in, but the beer came out fabulous after some cold conditioning.

Has anybody had this experience with Wyeast 1338?  My alt smells like
rottwn eggs (H2S).

There's a big difference between a rotten eggs smell from the yeast
(it does happen sometimes) and H2S.  PURE  H2S IS dangerous because it
contacts moisture (lung tissue) and forms concentrated Sulphuric acid
- which eats the mucus membranes.  That's the pure concentrated gas.

There is something called the "level of perception," where one becomes
aware of the chemical/odor and the "toxic limit value" where it
actually hurts/affects health.

Frequently, there is a wide disparity where the level of a toxin
becomes detectable, and where it actually causes damage.  There's also
the function of the olfactory sense becoming less sensitive to a toxin
as exposure increases . . .

Just cause you can smell it, doesn't mean it can hurt you.

I did have an exposure to H2S at a lab I worked at.  When I smelled
the gas, I held my breath.  The immediate problem was a mild headache.
Two days later I had a "cold."  These days I have "smoker's cough" and
don't smoke.

The type gas is less important than the concentration.

  Speaking of egg farts, if it's not too off-topic I would like to ask why
do farts smell like eggs immediately after eating eggs?  It's worse if the
eggs are runny, so what I figure is that the uncooked eggs undergo a
fermentation process before they reach the intestines... I can feel gasses
"growing" in the stomach for 3-4 hours after eating runny eggs.   But, the
timing doesn't seem right, I would think that at 98.6 degrees a complete
ferment would take twice as long.  However the eggy smell is immediate.  Are
there any common breakfast foods that would serve as some sort of catalyst?

I'm by no means an expert, I'm just trying to explain my observations.

Re: rotten eggs smell
Forbidden Fruit is a seasonal offered by Wyest. Has many of the same
characteristics as some p-abbey's. Don't worry so much if it is slight, the
phenols are quite impressive in this strain.

Re: rotten eggs smell
Got it too, using Wyeast 1728 (??) with the Scottish Ale kit I just bottled.
Funny thing about the smack pack was that it took 10-12 days to swell. Maybe
something was up with the yeast.

Anyways, wort stunk out of the airlock pretty bad of sulphur for 5-6 days
and then just went away. I'm a novice and was told by the pros in this NG
not to worry. By the time I racked and filled, the smell was totally gone.
They say it will be beer.

I'll let you know around Christmastime after it has conditioned. Hopefully
Santa will bring me two glass carboys.
