Weekly Wine Quiz: Hold Your Nose!

Vinted on August 17, 2012 binned in wine quiz

Welcome to the Weekly Wine Quiz, peoples.

Based on feedback from ever-so-vocal-and-intelligent peeps like you, I supply the quiz question each week, but do *not* supply the quiz answer directly in the post. That’s because YOU are supposed to supply the answer in the comments, and then tune back in later today in the comments section for the official answer. Because it’s more fun to keep you in suspense (and I’m a jerk like that). To make the suspense worse, I might be delayed in getting around to posting the answer since I’m on the road (again, again, again) this week – your patience is of course appreciated!

Today continues our recent theme on oak, with a decidedly stinky twist…

Hold Your Nose!

Wine barrels are often blamed as the culprit behind the animal and rubbery aromas associated with contamination of wine by yeast of the genus Brettanomyces. What is generally considered the perception threshold of “Brett” above which most people will be able to pick out those aromas?

  • A. 500 mg/l
  • B. 700 mg/l
  • C. 750 mg/l
  • D. 900 mg/l

Cheers – and good luck!





  • Dan G The Iowa Wino

    I'm going to guess lower is better so A. it is. Yes I am answering this without any wine in the glass…….. that part is next!

    • 1WineDude

      :) Thanks, Dan!

  • Jonathan Zeiger

    just a straight guess, 500?

    • 1WineDude

      Jonathan – bravely guessed! But will have to tune in later for the official answer. :)

  • Bob

    The numbers I've seen are between 420 and 450 so I'll go with 500

    • 1WineDude

      Thanks, Bob!

    Here's your slightly-delayed Official Wine Quiz Answer:

    A. 500 mg/l

    Some scientists, according to information cited by La Rioja Alta, S.A., believe that 500 mg/l is the average detection threshold for Brett-imparted aromas. Whether or not Brett is considered a flaw by those detecting it is a matter of personal opinion (this quiz question author tends to side with those who consider Brett a spoilage yeast).


  • Mark

    I've heard that 500 line as well….I know a couple of winemakers who swear the general public can't notice until you hit 50% higher than that and probably 2-3x that number in a tasting room environment.

    • 1WineDude

      Mark – wow. That would seem pretty high to me but I'm no chemist. I find I'm a bit more sensitive to it than most. Having said that, I don't really want a wine to be so squeaky-clean perfect that it lacks personality, but I get worried when the Brett seems to dry out the finish too much.
