The delicate ting of fine crystal stemware is as much a part of the enjoying fine wine as is the particular satisfying plop of a cork getting extracted. If you’ve ever sipped away from a fine crystal wine glass, you know it’s different from a plastic mug, or even a glass goblet. But the reason why? Is it just perception, or will there be really a discernible difference?
First, a couple of definitions are in order. Merriam-Webster defines glass as “any of various amorphous materials formed from a melt simply by cooling to rigidity without crystallization, ” and goes on to specify “an usually transparent or translucent material consisting typically of a mixture of silicates. ”
Merriam-Webster defines crystal as “a clear colorless glass associated with superior quality; also objects or ware of such glass. ”
In order the term relates to stemware and consuming glasses, we are generally talking about a transparent material made from a mixture of silicates. The most common type of glass is soda-lime glass, composed of about 75% silica. Interestingly, when lightning strikes fine sand, “fulgurites” can form, which is glass which is an impression of the lightning strike.
Determining the difference between crystal and glass is not exact. All crystal will be glass, but not all glass will be crystal. There are no universal rules that define crystal, and different countries make use of different standards for defining crystal. Having said that, the lead content of cup is the main determinant in the category of something as either glass or crystal. The amount of lead that defines crystal varies amongst nations.
In the European community, glass with 4 to 10 percent lead monoxide is designated glass. Glass using a lead content of 8 to 10 percent is called lead glass. Cup goods with a lead content associated with between 10 percent and 30 percent gain the designation of crystal. Goods containing more than 30% lead monoxide are called lead or leaded amazingly. In the United States, a lead monoxide content of 1 percent is sufficient for glass to be designated as crystal.
So as you can see, the meaning of crystal vs glass changes according to the country, even though the presence of lead is a determining characteristic.
Why is lead important? The presence of lead softens the glass, thus making it more easily cut and imprinted. Lead also increases the weight from the glass and causes the cup to diffract light. So glass is generally lighter in weight in crystal, plus light will not diffract through cup.
The problem with leaded crystal, nevertheless , is that lead can leach out of the glass, especially glasses that often are accustomed to contain wine or lead crystal decanters that store wine. Contact with lead can increase the risk associated with heart attack and stroke and can result in memory loss.
Today, unleaded amazingly glasses are offered by most major glass and crystal manufacturers. Lead-free crystal is not simply glass. Barium carbonate and zinc and titanium oxides replace lead oxide. This results in glasses with similar properties as lead crystal, such as temp control and the ability to accentuate fragrance and flavors of wine. Lead-free crystal has a similar refractive index to lead crystal, but is usually lighter.
Yes, wine glasses really can make a big difference in how wines tastes. If you’re drinking an everyday wine, such as your favorite mid-range Pinot gris or Merlot, you can use your everyday eyeglasses because your glass choice won’t create that much difference. But if you’re fortunate enough to be drinking a 2005 Pomerol from Bordeaux, you want to pay the utmost attention to the glass you choose.

You want the proper size, shape and materials to really appreciate such a fine – and expensive – wine.
It really is still under debate if the a result of stemware material on how wine tastes is a matter of aesthetics or perception, or if there is a reaction between wine and crystal. 1 theory is that crystal is rougher than glass and this roughness generates turbulence in the wine which, consequently, causes more aeration of the wine, and therefore more aromatic compounds are usually released.
Although the highest quality crystal eyeglasses provide a better wine tasting encounter, the high cost of these glasses helps prevent many from purchasing them. They are also very fragile, so you will have a high replacement cost. Fortunately, good-quality wine glasses are available at reasonable prices – including crystal stemware. You have to determine, depending upon how much you spend on wine and exactly how much of a hobby it is for you, if you need to pay for crystal wine glasses. Standard wine glasses cost around $50 a dozen, crystal wine glasses probably $75 a dozen. The best crystal eyeglasses, however , can fetch between $50 and $100 PER GLASS.
Further than the material itself, thicker cup can still create distortions which have an effect on what you see. The thinner the particular glass, the less between you and your wine, and thinner glass produces a finer stream of wine. This means that more air is mixing with the wine – here we refer to aeration again – so that a lot more aroma and flavor molecules are released.
