What You Need To Know About Wine Additives
Did you know that there are a lot of wine additives used to make wine?
Most wine additives are safe, however, there have been a few notoriously famous cases of unsafe wine additives in the past. Let’s get into the nitty gritty truth about wine additives and dispel some common wine additive myths.
Worst Case Scenario: A Wine Scandal!
In 1985, German wine quality control scientists discovered the presence of a commercial solvent, diethylene glycol, in some of their low-end wines. Diethylene glycol is a sweet-tasting toxic chemical sometimes used in anti-freeze. After the scientists discovered the chemical, they soon realized that the German producers were illegally blending Austrian wines with theirs.
While there were no reported casualties and the wines were pulled from the market, the media scare caused a long-term fear in consumers over wine additives.
Don’t worry, wine additives are now more closely regulated and the national electronic archives maintains a list of chemicals that are legally allowed for use in wine.
Common Wine Additives
Food products such as beer, juice and wine are unstable. Because of their volatile nature, processes have been developed to stabilize food products such as homogenizing juice. In the wine world there are many different wine additives, some of which have been used for hundreds of years with no ill effects.
The intention of these additives is not to adulterate the wine, but to stabilize it. Wines have the potential to last longer when they are stable. Many of these aren’t really additives at all, instead they glom (with molecular attraction) onto unwanted particles and are removed from the finished wine.
1. Sulfur
Sulfite sensitivity affects about 1% of the population. Wine usually has about 150 ppm of sulfur added whereas dried fruit has 1000 ppm.
Sulfites are used to kill unwanted bacteria and yeasts in the winemaking process. Since 1987, American producers have been required to mention the presence of sulfur if it exceeds 10 parts per million (ppm) in the finished wine. The EU recently passed a similar labeling law in 2005.
The laws are designed to help protect the small percentage of people who are sensitive to sulfur and should not be confused with the myth that sulfites in wine can give you a wine headache.
2. Yeast
Yeast is a eukaryotic microorganism that turns sugar into alcohol. Different kinds of yeast greatly affect the flavor of the resulting wine. Some winemakers prefer ambient yeast that is present on their winery equipment while other winemakers create a custom cocktail of cultured yeasts. Each method has unique benefits depending on the wine variety.
Vitamins! Yeast benefits from vitamins, minerals or any chemical compound that helps keep the yeast alive in grape juice during fermentation. For instance, Thiamine Hydrochloride is a B Vitamin which helps keep yeast happy in high alcohol wines over 14% ABV.
3. Tannin
Tannin is one of the 4 traits that makes wines age-worthy. Wine grapes are full of seeds which are very tannic. The seeds are crushed with the grapes to add structure to wine. Oak aging also adds small amounts of tannin as the wine is exposed to the oak wood.
Oak Chips Are More Sustainable It’s widely accepted in Europe to use oak chips and tannin powder in wine. While oak chips are not as romantic as a room full of oak barrels, they are better for forests and are cheaper to transport.
4. Sugar
Chaptalization is the process of adding sugar to grape juice in order to increase the final alcohol level in the finished wine. Adding sugar doesn’t make a wine sweeter because the sugar is consumed by the yeast when it is fermented into alcohol. Chaptalization can add up to 3% ABV to a wine. It is legal in areas where grapes struggle with ripeness, such as Bordeaux, France and Oregon.
Illegal in Some Areas! Adding cane sugar is not legal in California, Argentina, Australia, Southern France and South Africa. Producers can add sugar rich grape concentrate to simulate the same results, as the use of grape concentrate is not considered chaptalization.
5. Fining & Clarification
After a wine has been freshly fermented it goes through a period of stabilization. The chemicals added during this process are designed to pull unwanted characteristics out of the wine. For instance, copper sulfate is added to remove free sulfur in a wine. The copper has the same effect as putting a penny in wine to remove undesirable smells. Afterwards the copper sulfate is removed from the wine.
Why Are There Non-Vegetarian Wine Additives?
For many hundreds of years in Italy and France, winemakers would add an egg white or two to a large barrel of wine. The proteins in the egg white would bind to free proteins suspended in the wine. After a short wait, the egg white and free proteins would precipitate out of the wine and drop to the bottom of the barrel. Winemakers would strain the clear wine off the top and leave the sludge. This process is called Fining and Racking. Nowadays, there are more advanced ways of achieving the same results including numerous microbial products (read: totally vegetarian!) that perform the same function.
COVID-19 Impact on the Electronic wet chemicals Market
The global wet electronic chemicals market includes major Tier I and II suppliers like Avantor Inc, BASF SE, Cabot Microelectronics, Honeywell, and Kanto Chemical Co. Inc. These suppliers have their manufacturing facilities spread across various countries across Asia Pacific, Europe, North America, South America, and Middle East & Africa. COVID-19 has impacted their businesses as well.
These players have announced the suspension of production due to the lowered demand, supply chain bottlenecks, and to protect the safety of their employees in the US, France, Germany, Italy, and Spain during the COVID-19 pandemic. As a result, the demand for electronic wet chemical sis expected to decline in 2020. Manufacturers are likely to adjust production to prevent bottlenecks and plan production according to demand from tier 1 manufacturers.
Electronic Wet Chemicals: Market Dynamics:
Driver: Technological advancements in the electronics industry
Market penetration of electronic wet chemicals has risen in the electronics and semiconductor industries. They are increasingly used in modern technology industries such as new energy, modern communications, computers, information network technology, microcomputer mechanical intelligence systems, industrial automation, and home appliances.
Electronic wet chemicals are ultra-pure nature due to which they are extensively used in cleaning and etching application during semiconductor production and processing. The recent commercialization of nano-based devices has boosted the market potential for photoresist and etching chemicals with various technological advancements. Also increase in the use of semiconductors and integrated chips in manufacturing of electrical components gives rise to the electronic wet chemicals market in the estimated period. Therefore, rise in the demand for building electrical components due to various technological advancement in the electronics industry is predicted to be the major driving factor for the electronic wet chemicals market in the estimated period.
Introduction
Like other industries, the pulp and paper industry (referred to in the rest of this paper as ''the industry"
has come under increasing scrutiny for its potential environmental impacts. More than many other industries, however, this industry plays an important role in sustainable development because its chief raw material—wood fiber—is renewable. The industry provides an example of how a resource can be managed to provide a sustained supply to meet society's current and future needs. Pulp and paper additives also plays an important role in this industry.
