(Wine-Searcher) - Students mark the restoration of their country with an unprecedented wine.

The 25th anniversary of German reunification might have sparked protests over immigration on the weekend, but one group of students found a more palatable way to mark the reconciliation of east and west.

Enology students came up with a unique product to celebrate the 25th anniversary of unification – "Einheitswein", an unprecedented blend of wines from all German wine growing areas, according to Germany's international broadcaster Deutsche Welle.

"This is a perfect symbol for German unity," said Professor Erik Schweickert, who teaches international wine business at Geisenheim University in the Rheingau wine-producing region.

Schweickert headed a year-long project involving hundreds of students, with the aim of blending wines from all of Germany's 13 wine-growing regions in both west and east. This was a first for German wine as, normally, blending wines from different regions is forbidden. German wine regions stretch from the Mosel on the Luxembourg border in the west to Saxony, near the country's eastern border with the Czech Republic.

"We chose a wine from each region, and different kinds of businesses: bulk wine producers, bottled wine producers, organic wineries, cooperatives," Schweickert told Deutsche Welle. "We wanted to create a picture of the German wine business in its total."

Their "Einheitswein" (unity wine) was chosen as the official wine at the celebrations on Saturday in Frankfurt, to be presented to and tasted by German politicians and foreign heads of government. In reality there were two wines produced, a red and a white.

The 2014 vintage, Professor Schweickert said, was "a challenge due to end of season rainfall." But, in the end, they found suitable wines – that is, wines that had not been chaptalized.

In addition to providing wine for Germany's official unification celebration, the group sent bottles to the world's 100 top wine journalists and bloggers. "Reaction has been positive so far," Schweickert said.
