The Jansen ink manufactory offers a variety of wine inks, of which the following were tested: Bordeaux, Barolo, Blauer Portugieser, Lemberger and Dornfelder. As expected, each of these inks has a typical scent corresponding to the respective wine; above all the clear colour differences are remarkable, since each ink has its own character. The writing test was carried out with a Montblanc Meisterstück 146 with an OBB nib and a Montblanc Meisterstück with an OM nib on normal copy paper. Since copy paper usually does not have particularly high quality, fraying at the edges can occur with more flowing inks. On higher-quality papers this effect does not appear.
