The Provable Theory of Terroir

The Provable Theory of Terroir
July 02, 2021
Twenty-seven compounds were quantified and used to classify and/or discriminate Malbec wines. Those compounds included 12 anthocyanins and 15 LMW phenolic compounds comprising phenolic acids, flavanols, stilbenes and phenyl-eth- anol analogues.
ONE AFTERNOON IN 1981, Dr. Ralph Kunkee sat on my porch along with nine winemakers from Sonoma Valley. Kunkee was the microbiology specialist at UC Davis for 30 years, focusing on wine yeast, malolactic fermentation, and the sources of microbiological spoilage in wine. I had invited him to give a 15-minute lecture on his specialty and then followed up with a 90-minute question and answer period with the winemakers. ....

What's Causing Your Wine Headache? It Might Not Be Sulfites

Sulfites have been said to cause adverse reactions in some wine drinkers, but a recent research paper by Sophie Parker-Thomson argues that bottlings made without added sulfites might be more apt to generate symptoms like headaches or watery eyes.
Instead of sulfites, Parker-Thomson writes, the culprit is more likely to be a group of compounds called biogenic amines (BA).
Present in all fermented food and drink, biogenic amines increase with food spoilage. They’re produced from amino acids via enzymic activity in living organisms like microbes, most often a subset of bacteria. The best-known biogenic amine, histamine, is produced when microbes remove carbon dioxide from the amino acid histidine. ....

The Catena Institute of Wine Publishes Groundbreaking Article in the Most Extensive Terroir Study of Any Varietal Wine
Mendoza, Argentina – February 3, 2021 – The Catena Institute of Wine announces the publication of groundbreaking research, irrefutably proving the existence of terroir and its persistence across vintages. The article, “Terroir and vintage discrimination of Malbec wines based on phenolic composition across multiple sites in Mendoza, Argentina,” appears today in Scientific Reports, one of the most-cited journals in the world. The Institute chose to submit the study to Scientific Reports, a Nature Research journal, because of its rigorous peer review acceptance process and open access making it available to everyone. ....

Catena Institute finds 'irrefutable proof' of terroir

Catena Institute finds ‘irrefutable proof’ of terroir
4th February, 2021
by
Rupert Millar
The Catena Institute of Wine has announced the publication of a new paper which it says, “irrefutably proves the existence of terroir and its persistence across vintages”.
A long-debated term in wine, its meaning and even existence supported and dismissed by generations, the study set out to find if wines (not grapes or must) from different sites could be identified by a chemical fingerprint.
Published today in the journal
The researchers compared wines from four different levels of terroir in Argentina’s Mendoza – focusing on 23 individual parcels smaller than a hectare distributed across three large regions, six departments, 12 geographical indications and over three vintages (2016, 2017 and 2018). ....
