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.

If Your Spouse Smells Wrong, What Do We Learn?

The spread of SARS-CoV-2 has caused an associated pandemic of anosmia, the loss of smell. That could lead to scientific breakthroughs.

Room temperature is cooler than you think; chilled doesn’t mean straight-from-the-fridge

The pigments responsible for a wine’s colour also change its flavour

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?

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.
