Copper drinking glasses have long been a popular choice among drinkers looking for a simple yet stylish alternative to a full glass of wine.
And now, they’re becoming a thing of the past.
Copper drinking glasses are a thing now, according to a new study by researchers at the University of California, Berkeley, and the University Of Colorado, Boulder.
The study, which was recently published in the journal ACS Nano, found that the average number of copper drinking glasses sold worldwide has dropped by more than 50 percent since 2008, and that copper drinking is a niche market.
The researchers examined sales data from Nielsen’s “Top 50” list of beverage consumption, and found that in 2014, there were more than 4.5 million copper drinking devices sold worldwide.
More specifically, the researchers found that while there are now more than 1.5 billion copper drinking products in the world, the market share for those products dropped from 20 percent to just 2.5 percent in 2014.
The study authors note that this trend is likely due to the fact that more people are now opting for more environmentally friendly alternatives to wine glasses.
According to the study, “In contrast, the consumption of copper wine glasses declined in 2014 by 43 percent.”
The findings are troubling, because they could mean that many people are turning to the copper drinking market for more economical options, such as stainless steel drinking cups.
“We think that these declining numbers reflect the fact, and may also be linked to, a shift away from copper drinking in general, and from copper wine in particular, to a more socially acceptable alternative to copper drinking,” said senior author Michael Bocciardi, a professor of chemistry at UC Berkeley and lead author of the study.
