Today's ink is Robert Oster Barossa Grape. I purchased my sample of ink from Anderson Pens.
Barossa Grape is a beautiful dark purple.
There is a strong blue undertone, and lots of depth.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 30 seconds
Water resistance: Low
Show through: Medium
On 20 pound copy paper the ink performed well, no issues that I noticed.
I used a broad Pilot Vanishing Point Twilight on Tomoe River paper. The ink had an average flow.
Overall, I love the shading and depth this ink has. It's a beautiful color, it would be great to use in autumn.
