Red fountain pen ink made with wine from DeAtramentis, handmade in Germany.
Zweigelt is a red wine grape variety developed in 1922 by Fritz Zweigelt. It was a crossing of St. Laurent and Blaufränkisch. It is now the most widely grown red grape variety in Austria, as well as having some presence in Canada's vineyards.
This ink is made by hand in small batches, therefore there could be some color variation between bottles of ink.
