Weekly Wine Quiz: Octalactating

Vinted on August 24, 2012 binned in wine quiz

Welcome back to the Weekly Wine Quiz, my friends!

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. This week, we’re wrapping the foray into the science of oak aging, with a not-so-easy question to put your wine smarties through the staves…


Methyl octalactones imparted to wine by the wood from aging in oak barrels can be an important source of aroma development in wines meant for aging. What aroma characteristic do they give to a wine?

  • A. Leather
  • B. Vanilla
  • C. Toasted bread
  • D. Coconut

Cheers – and good luck!

    Alrighty, folks, here is the Official Wine Quiz Answer:

    D. Coconut

    The coconut smell that often marks older wines that have been aged in oak is the result of methyl octalactones, isomers that originate from lipids. These are often seen in older Gran Reserva wines from Rioja, which undergo significant periods of aging in American oak.

    I would have thought vanilla…

    • 1WineDude

      zed – me, too, actually. But my source says differently. :)
