The world’s oldest Italian wine in a large storage jar from the Copper Age
The discovery is detailed in Microchemical Journal
Chemical analysis conducted on the ancient large storage jar tested positive
Florida, USA, August 25, 2017: Researchers from the US have found evidence of the world’s oldest Italian wine in a large storage jar from the Copper Age which indicates that winemaking in the region began as early a fourth millennium BC.
The discovery, detailed in Microchemical Journal, could dramatically predate the commencement of winemaking in Italy.
Traditionally, it has been believed that the production of it developed in Italy in the Middle Bronze Age (1300-1100 BC).
Chemical analysis conducted on the ancient large storage jar tested positive.
Lead study author Davide Tanasi from University of South Florida in Tampa, US, conducted chemical analysis of residue on unglazed pottery found at the Copper Age site of Monte Kronio in Agrigento, located off the southwest coast of Sicily.
The team determined that the residue contains tartaric acid and its sodium salt, which occurs naturally in grapes and in the winemaking process.
The researchers are now trying to determine whether it was red wine or white wine. (IANS)

When it comes to social media penetration in daily life, a majority of Americans are hooked on Facebook and YouTube but millennials prefer photo-sharing platforms Snapchat and Instagram, a new survey has revealed.
According to the Pew Research Centre, 68 percent of all Americans use Facebook and three-quarters of that access the social media platform on a daily basis.
Nearly 74 percent of adults use YouTube and 94 percent of young users visit YouTube on their computers or smartphones.
With the exception of those 65 and older, a majority of Americans across a wide range of demographic groups now use Facebook.
“Younger Americans (especially those ages 18 to 24) stand out for embracing a variety of platforms and using them frequently. Some 78 percent of 18- to 24-year-olds use Snapchat, and a sizeable majority of these users (71 percent) visit the platform multiple times per day,” the findings showed.
Similarly, 71 percent of Americans in this age group now use Instagram and close to half (45 percent) are Twitter users, the survey noted.
“These findings also highlight the public’s sometimes conflicting attitudes toward social media. For example, the share of social media users who say these platforms would be hard to give up has increased by 12 percentage points compared with a survey conducted in early 2014, the Pew Research Centre said.
By the same token, a majority of users (59 percent) say it would not be hard to stop using these sites, including 29 percent who say it would not be hard at all to give up social media.
Some 88 percent of 18- to 29-year-olds indicated that they use any form of social media. That share falls to 78 percent among those ages 30 to 49, to 64 percent among those ages 50 to 64 and to 37 percent among Americans 65 and older.
Pinterest remains substantially more popular with women — 41 percent — than men (16 percent). LinkedIn remains especially popular among college graduates and those in high-income households.
“Some 50 percent of Americans with a college degree use LinkedIn, compared with just 9 percent of those with a high school diploma or less,” the survey said.
The messaging service WhatsApp is popular in Latin America, and this popularity also extends to Latinos in the US – 49 percent of Hispanics report that they are WhatsApp users, compared with 14 percent of whites and 21 percent of blacks. IANS
