Odd that nobody has brought up the subject of “higher alcohols”.
From my observations (and a few comments from winemakers), higher octane wines seem to produce a higher % of higher alcohols.
IMO, it is the added presence of these puppies that add to the negative experiences…
Paul, methinks you could be on to something! I have never heard of “higher alcohols” in wine. I’ve been following the thread and like others have been puzzled by the dramatic effect that Frank sees with the higher alcohol wine with what to me seems to be only a marginal increase in alcohol (as Anton and others have pointed out). The thought that he may be seeing a dramatic increase in the “higher alcohols” with these wines and that is what he is reacting to is an interesting hypothesis. I did a little googling about the subject and came across this comment": "Fusel oil” is the term given to all the higher alcohols present within a wine (Boulton et al., 1996). The German word “fusel” literally translates to “rot gut” or “bad liquor”. Frank may be reacting to this “rot gut” stuff ! Thanks for posting.
It is stone cold hard to find data regarding that aspect of wine.
Regardless of ABV, these can vary from wine to wine, vary by yeast, all sorts of factors.
I stole this from Waterhouse Labs / UC Davis…
Check out all the variability: “The amount produced during fermentation is dependent of the genus, specie and strain of yeast, the specific nutrient status (nitrogen and amino acids) and composition of the must and temperature, aeration and pH during fermentation.”
They never mention the wine ABV, but do mention that these become more important in distillates. And a fun typo: “Higher alcohols have a major importance in wine distillate (grape spirits or brandy), due to the fact that in distillates higher alcohols are found in grater concentration.”
what are “higher alcohols”? What does it mean to say that “higher octane wines seem to produce a higher % of higher alcohols”? Obviously higher octane wines have a higher percentage of alcohol, are you saying something beyond that? thanks
Basic chemistry. Methanol and ethanol are simple alcohols, complex ones (more carbon atoms or -OH groups) are higher alcohols.
Higher alcohols are normally considered impurities and they are thought to give the characteristic aromas and flavors to grappa.
“higher octane wines seem to produce a higher % of higher alcohols” means that a wine with high % ABV must have also a higher concentration of higher alcohol compounds than a low % ABV wine.
Similar experience to those already posted. An added benefit to low alcohol but higher acid wine is, many easily retain their freshness for 3-4 days, more than higher octane wines IMHO. Less pressure feeling the wine will go to waste, and a leisurely time frame for consuming it. (Love also half bottles) of 2016 Rhys Bearwallow Pinot and 2005 Baumard Quarts de Chaume that are on deck to share with friends tonight
I find in general I drink sparkling wine slower than say a higher alcohol, lower acid non effervescent wine. Higher acid and effervescence leads to smaller sips and need for palate recovery in between possibly? Higher alcohol Zin ect is just more gulpable and the setting usually allows for that. They are cocktail wines and for me are often consumed as such. There is a place for all in my life but I’m also trending away as time goes on.
