Phenolic matrix effect on aroma formation of terpenes during simulated wine fermentation – Part I: Phenolic acids
There are more than 1000 volatile components in wine, contributing to aroma. And it has been proved that non-volatile substances of wine, such as polyphenols, polysaccharides and proteins have large influence on the release and perception of aroma compounds, which is called matrix effect.

The pigments responsible for a wine’s colour also change its flavour 12 March 2021 11:15 |

The pigments responsible for a wine’s colour also change its flavour
Anthocyanins not only give wine its colour, they also change its flavour. That is according to Maria Alessandra Paissoni, from the University of Turin, speaking at the latest Enoforum session on winemaking.
As part of her PhD, the Italian researcher began by extracting all the anthocyanins from a Barbera and a Nebbiolo vinted in 2015. “Then I divided them into three groups according to their level of acetylation, glucoside, acetyl-glucoside, or coumaroyl-glucoside” she explained. She then put each fraction in the presence of salivary proteins. “The higher the acetylation level, the more the anthocyanins precipitated them”, she said. Paissoni organised sensory analysis sessions with trained students from the Bordeaux Institute of Vine and Wine Sciences.

A Good Nose: Can Dogs Detect Wine-Tainting Molecules? 12 March 2021 11:21 |

A Good Nose: Can Dogs Detect Wine-Tainting Molecules?
International vintners depend on dogs to find wine-tainting molecules
Alejandro Fantoni Sr. was waiting in an airport security line when one of the detection dogs caught his attention. Fantoni struck up a conversation with the handler.
“[My dad] started talking with the trainer of the dog, asking, ‘Can you train dogs to detect any kind of aroma or different scents at a very low concentration?’ and the guy said yes, it was possible,” says Alejandro Fantoni Jr.
Based on the conversation, the elder Fantoni decided to start a first-of-its-kind dog detection program at TN Coopers, a Chile-based cooperage that makes handcrafted wooden barrels for international winemakers.

International Organization of Vine and Wine (OIV) Officially Incorporates NMR Method in Compendium of International Methods of Analysis of Wines and Musts
ETTLINGEN, Germany--(BUSINESS WIRE)--Nuclear magnetic resonance (NMR) spectroscopy has been incorporated by the intergovernmental and International Organization of Vine and Wine (OIV) in its compendium of International Methods of Analysis of Wines and Musts, for the quantification of six key parameters in wine – glucose, malic acid, acetic acid, fumaric acid, shikimic acid and sorbic acid.

Liking plus coolness – what makes a wine great
Why are some wines so hotly sought after? Which bottles do you go ‘wow’ at, when someone pulls them out at a wine dinner? Why are some wines almost mythical in their reputation, while others equally well scored in blind tastings never in that peer group?

What’s the Right Temperature for Your Wine? (Video)
Part of relaxing at the cottage is often enjoying a glass of wine on the deck or the dock, but which wines, and how do we keep them cool when temperature soars?
That’s what we chat about on Global Television’s Morning Show.

Handling wine pomace: The importance of drying to preserve phenolic profile and antioxidant capacity for product valorization 04 August 2021 21:02 |

Handling wine pomace: The importance of drying to preserve phenolic profile and antioxidant capacity for product valorization
The wine industry and valorization of wine pomace
Like other industries, winemaking produces waste. Wine pomace (WP), composed of stems, seeds and skins of grapes, is the main solid organic by-product and it represents approximately 25% of total grape weight used in the winemaking process 1. WP is commonly valorized for the production of distilled spirits (e.g. Grappa), tartaric acid, and animal feed 2,3. Still, the most common practice is to use it for composting and agriculture spreading, which comes with environmental drawbacks. WP is rich in phenolic compounds, which are slightly acidic molecules but in high volumes and concentrations they lower the pH of the soil and increase oxygen demand in ecosystems 1,2. Phenols are also known for their antioxidant capacity and are associated with the prevention of certain chronic diseases 4,5. As such, there is an economic opportunity for valorization in the fields of health and nutraceuticals as the consumers’ demand for bio-sourced products is on the rise.

It is probably safe, at this distance in time, to confess. The PR who organised it is dead; those at Rémy Martin will have moved onwards, upwards, outwards. It was, in any case, not very important.

FARMING WINEGRAPES FOR AROMA, FLAVOR, & COLORS
For many wine drinkers, the most important characteristic of a wine is its flavor. While sugar (sweetness and alcohol strength), acidity (tartness), and color related compounds (astringency and bitterness) in grapes contribute to wine flavor, the taste characteristics most unique to a specific wine are usually associated with distinct aromas. We humans can sense and distinguish minute amounts of the volatile compounds contributing to the bouquet of a wine.

WHY WINE MOVES US 27 September 2021 19:10 |

WHY WINE MOVES US
I’ve always been very aware of the number of variables attached to any wine by the time it reaches the bottle. Sunshine hours, aspect, viticultural intervention, water supply, the natural variation attached to an individual fleck of soil, yeast choice, atmospheric composition of the cellar, warehouse, vineyard, etc. As I start to make my list of variables, hundreds more flood to my mind. Yeast, fermenter temperature, fermenter shape, the role mother nature plays in the seasoning of a stave, cork, and well…maybe the winemaker’s mood is somehow even reflected in the task at hand on any given day.
