Sulphur or Petrol?

#1 Post by Brian G r a f s t r o m » January 3rd, 2011, 7:43 pm

How do you tell the difference between the two? Based on the TN's I read, it seems some people use the two interchangeably (or mistake one for the other); you had, imo, an enlightened answer to the "how do you describe minerality?" question, and I'm wondering if you can work your magic on this one, too.


... or is this question like asking how do you tell the difference between apples and oranges?

The SO2 aroma is that of a lit matchstick. The H2S aroma is that of a rotten egg or a stinky cheese.

The so-called "petrol" aroma is neither of these. It's explained in my Germany catalogue. Well actually, I stole the explanation from Tom Stevenson. It has to do with a development of lutein, but I'm an ignorant oaf about such things and have no idea what "lutein" might be, or whether I have any of it in my office, kitchen or other rooms.
