One of my students brought me a homebrew and asked,
"Can you tell me what we did wrong? This stuff
smells like ass."

I let the bottle age in the fridge a couple weeks,
and finally, last night, I and another experienced
homebrewer cracked it open. We have our opinions,
but I'd like more:

The initial whiff is "jalepeno." This was not
a jalepeno beer. I've forgotten what style he
was trying for, but it was something "normal."
So no peppers in the beer. The second whiff
was more like bell pepper. Neither of us knew
anything that would give a pepper aroma to a brew.

The very little that we tasted was almost OK to
drink. There was a slight sour taste at the end
which made us think of an infection. So our best
guess is "some kind of infection that produces a
jalepeno/bell pepper smell." There was no ring
around the neck of the bottle and the beer had
good clarity. No haze or floaty threads.

The student asserted that the aroma was real
strong. We didn't find it strong, so maybe the
extra aging mellowed things a bit. Our second
guess was that the hops just needed to settle
down, and perhaps the beer would be fine in a
month or so.

So the main question is "Anybody have jalepeno
before without actually adding the pepper?"

(And, yes, we professor types are very wary of
ingesting anything a student brings us. "Thanks
for the cookies. I'll eat them later....")

It would help if we could see the recipe.

Working on it. Classes are over for the Summer, so he may
be in hiding for a while. I have an e-mail out to him...

Good. I'm leaning toward the hops at this early stage.

Hah! Student replies: "I started with a pilsner brew and
put a hop bag full of roasted jalapeños
and three zested limes. I probably should have pulled the peppers instead
of leaving them in the whole time. The pepper taste is a bit intense."

Ummm...There's yer problem, raht there. Comments welcome.

Since you didn't know about the Jabs I consider that some very good
detecting. What concerns me a bit is why would you sample a brew that
"smelled like ass" ?

Well, as I said, we profs are very cautious about ingesting
student offerings. I did conjure up a picture of a frat boy
telling his friends, "I gave Dr. Goddard some of our Diarrhea
Dunkel and he actually drank it! Har guhyuk guhyuk!"
I didn't swallow.

"I didn't swallow." sounds a little like Bill Clinton.
I taught in a technical High School for 20 years, I too was leery of
food offerings.

Here's a thread. I think the main suspect was added coffee, which may
not be the cause here --

flavor.76252/

Or maybe it's a combination of a peppery yeast and a vegetal hop
contribution?

Maybe it's a residue from poorly cleaned or rinsed bottles?
