Diamine Espresso is from the 2017 150th Anniversary collection from Diamine. So far, I have liked the collection. I purchased my sample from Vanness Pens.
Espresso is a light brown, with a cool tone.
In ink drops, Espresso almost looks like black velvet.
Dry time: 42 seconds
Water resistance: medium-low

Ink swabs for comparison, left to right (top to bottom for RSS): Pilot Iroshizuku Yama-guri, Diamine Espresso, and Diamine Cult Pens Deep Dark Brown. Yama-guri is a bit cooler than Espresso, and Deep Dark Brown is a bit warmer and darker. Click here to see the Diamine ink swabs together.
I started with the Pilot 912 FA, and then switched to a broad nib. I love seeing the shading and sheen in the broad nib.
Overall, this ink is really well behaved. It's a nice color, and has some sheen and shading to it. I think I need a full bottle of this one.
