Every wondered what is going on within your glass of chardonnay or Shiraz? How the aromas and tastes are formed to make the perfect glass of vino? The American Chemical Society has put together an entertaining video to explain more.
Meandering down the wine aisle in a supermarket can be a daunting task, especially as the rage of wines available seems to expand every few months. The problem is that each bottle has its own nuances of taste and smell.
Wine experts use terms that can baffling and those with a well-developed pallet or a refined nose can pick up tastes and scents that others find had to detect. How can wine, produced from grapes, really smell buttery or taste like grass?
The American Chemical Society has put together a presentation about the complex chemistry about wine, via its Reactions series.
The two wines featured in the video are chardonnay and Shiraz. These are among the two most popular wines in the world. Chardonnay is a green-skinned grape that originated in the Burgundy wine region of eastern France. It is now grown in most wine regions around the world. Chardonnay can be used in almost any style of wine making, ranging from dry still wines to sparkling wines.
Shiraz (or Syrah) is a dark-skinned grape variety grown throughout the world. The grape, originating in France, is used to make red wine. Although found in most wine regions, the characteristic of the grape (and also the wine) is influenced by the soil and climate.
Both chardonnay and Shiraz are popular wines. As to the most popular wines in the world, the University of Adelaide in South Australia recently compiled a list, based on a global survey and reported in International Business Times. There are some 1,270 grape varieties in the world – a large number, and from this the top ten wines are:
Top Wine Grape Varietals Worldwide (Including Origin and Market Share) are:
1. Cabernet Sauvignon (France; 6.3 percent of the market)
2. Merlot (France; 5.81 percent of the market)
3. Airen (Spain; 5.48 percent of the market)
