Is There A “Correct” Temperature For Wines? 20 December 2019 13:56 |
Beheerder Registratiedatum: 9 jaren geleden Berichten: 8.971 |
Is There A “Correct” Temperature For Wines?
Among the many myths about wine service, which include sniffing the cork, using a particular glass for a particular wine and decanting this year’s vintage, the idea that there is a “correct” temperature at which a wine should be served is largely bogus. For outside of suggesting a white wine is preferably served cool and a red wine not too warm, the parameters for what is right and wrong meld somewhere around 65 degrees F.

Don’t underestimate the power of your nose. It makes our everyday eating experience pleasant and interesting and it warns us of spoiled food, corked wine and the dangers of gas and smoke. It evokes strong emotional reactions, influences sexual attraction and can be used as a sensitive analytical instrument.

Using Internal Visual to Calibrate the Structure in Wine
A belated Happy New Year to everyone! I hope the holidays provided some much-deserved quality time off with family, friends, and most of all solo down time. This is the time of year when people tend to make resolutions about various things including health, saving, being on time, etc. However, I don’t make New Year’s resolutions. In the past I’ve found that any resolutions I make are quickly forgotten after, causing needless pseudo-guilt and moments of almost sort-of pretending to feel bad.

A study identifies 17 key compounds in wine aromas
Maybe words such as ethyl butanoate and octalactone sound unfamiliar to most people who drink wine. However, these substances are some of the ones that give this popular drink its own scent. A recent piece of research published by the University of Cordoba and the Gheorghe Asachi Technical University in Romania identified a total of 17 key compounds in the aroma of red wine, made from a red grape variety harvested in the wine region in northeast Romania.

Minerality in wine: from the ground up 04 February 2020 16:01 |

Minerality in wine: from the ground up
Dr. Jamie Goode notes that as a descriptor, minerality didn’t crop up in the wine industries lexicon until at least the mid-to-late 80s. In a recent Decanter article Prof. Alex Maltman recalled writing his first piece on the topic a little over 15 years ago. Maltman posits the term to be of ‘pragmatic usefulness’ despite there being no clear consensus on what it actually means. We wine-lovers are relentless in our indulgent pursuit of translating perception and sensation of wine in to sometimes overly simplistic terminology. Vast may our parlance be, minerality is arguably amongst the most ubiquitous of its terms. Why is the topic so challenging? Is it helpful? What do we know about it? In this piece I will explore the research and piece together my thoughts.

An example of why smelling a wine cork matters 07 February 2020 18:31 |

An example of why smelling a wine cork matters
Recently I wrote about the importance of smelling the cork when opening a bottle of wine. The argument goes that it gives another opportunity to pick up cork taint – a contaminant, such as trichloroanisole (TCA), that ruins wines and can alternately make them smell or taste muted or, at higher levels, like a moldy basement.

Abstract
Brettanomyces bruxellensis is the main wine spoiler yeast all over the world, yet the structure of the populations associated with winemaking remains elusive. In this work, we considered 1411 wine isolates from 21 countries that were genotyped using twelve microsatellite markers.

Acacia gum stabilizes color in wine, finds Alland & Robert
Alland & Robert, international supplier of acacia gum, and Biolaffort, a private enology researcher, have teamed up to understand the properties of the 100 percent plant-based natural gum, sometimes referred to as gum arabic. Acacia gum, which is used throughout the food industry to generate texture, emulsify and stabilize, is widely used in winemaking. Its presence, even in small amounts, has been shown to preserve the color of wine, and in the long term, limit the appearance of sediment by stabilizing the coloring matter. Thanks to the collaboration, a deeper technical understanding can be formed, which builds on the tradition of using acacia gum in wine throughout southern Europe’s winemaking countries.

Researchers in China have applied an array of sensors—an electronic nose—that can sniff bouquet of rice wine and offer an estimate of the vintage. Writing in the International Journal of Computer Applications in Technology, the scientists explain how their artificial olfactory system takes data from sensors sampling a rice wine and uses a computer to carry out a statistical analysis of the signals to give an essentially 100 percent accurate age for the wine.

Extended harvest date alter flavonoid composition and chromatic characteristics of Plavac Mali (Vitis vinifera L.) grape berries 26 October 2020 18:31 |
Beheerder Registratiedatum: 9 jaren geleden Berichten: 8.971 |
Extended harvest date alter flavonoid composition and chromatic characteristics of Plavac Mali (Vitis vinifera L.) grape berries
Each year, appropriate harvest dates receiving great attention due to their irreplaceable role in natural modulation of the wine style in the vineyard and reduction of production costs in winery. The enological potential of the berries depends on the quantitative and qualitative polyphenolic profile of the berries in the time of harvest 1,2 and their extraction during vinification 3,4,5. Harvest before berries reached technological maturity, known as cessation of active sugar accumulation, is associated with fresh wines, low in alcohol, high in acids, with a light and vivid color, thin body, bitter taste and astringent sensations 1,2. Peak in aromatic and flavor complexity, fruity scents and full body, soft tannins wines are associated to phenolic maturity of the grapes 4,6,7. Extended hang time is controversial issue as in certain vintages gives extraordinary quality 2,3,8 however, compromised wine quality potential is reduction of natural acidity, increase in pH, reduction of anthocyanins, shift in color toward violet, reduction in polyphenols and color 6,9 and a prevalence of cooked, jammy and waxy types of aromas and flavors of raisins 1.
