Monteverde Yosemite Green Ink Bottle - 30ml

Monteverde Yosemite Green Ink Bottle - 30ml

This 30?ml glass bottle from Monteverde is part of their Core Collection — a series of vibrant, nature?inspired fountain pen inks. According to the manufacturer, the Core Collection inks are crafted “rich in color, vibrancy, and brilliant hues” and are compatible via their ITF™ (Ink Treatment Formula) technology.
Specifically, Yosemite?Green is described by reviewers as a “lovely deep green… solid forest?y green colour” with good saturation. One review described it as a “yellow?green with slightly bluish tint” and noted a “gorgeous maroon sheen” under certain conditions. 
In short: it offers a rich, somewhat forest?green tone that may carry subtle bluish undertones, good saturation, and under broad nib / high quality paper conditions, some shading and sheen may emerge.

• Colour / Shade: “Yosemite Green” – green ink in the Monteverde Core line.

  • Bottle specification includes ~23.5?mm opening diameter in the 30?ml version.

Performance & Behaviour

Based on user reviews and tests:

• Flow & writing performance: One reviewer described the ink as “wet and flows quite nicely in my medium nib” when used in a vintage pen.

• Shading & Sheen: On high?quality papers, shading and even a maroon sheen were seen (“gorgeous maroon sheen in ink splats”).

• Dry time / water resistance: This ink is not marketed as waterproof and has no special water?resistance claims.  Some users noted that the dry time and cap?off extension claims are not always significantly different from other inks.

• Color on various papers: Reviewers note that on cheap/absorbent paper the full richness of the shade may diminish; one noted it works well on good paper and showed “bright saturation”.

• General aesthetics: The green appears rich and deep rather than bright lime; it’s described as appropriate for journal writing and everyday use rather than flashy.

• If you’re looking for a green ink that is more than just “basic green” — something richly saturated, capable of shading and a bit of visual interest (with possible sheen) — Yosemite?Green fits well.

• Suitable for writing, journaling, note?taking, fountain?pen enthusiasts who like a refined green that doesn’t scream neon but still stands out from black/blue.

• With the ITF formula designed to help with flow and pen?feeding, it may give smoother performance (particularly in pens that are less wet) though individual results vary.

• Because the shade is relatively deep, if you were expecting a vivid bright green like a lime or pastel, you might find it more muted/forest rather than very bright. One reviewer expected something brighter and described Yosemite as “lovely deep green, however my preference is for something a bit brighter”.

• On lower grade paper (thin, absorbent, cheap), you may see feathering, less shading/variation, or show?through. Using fountain?pen?friendly paper will bring out the best.

• Dry time and flow behaviour vary based on pen, nib size, paper, even ink age; the claims of “extended cap?off time” may be less dramatic in practice.

• While there is no specific large?scale issue referenced for Yosemite?Green, the broader Monteverde ink line has some user?reported issues historically (e.g., smell, contamination) though many bottles and users report no problems. One user on Reddit states:

  “I use Yosemite Green every day since November 2022 and no issues with frequent refills.”
  So while not unique to this shade, good practice: inspect bottle on arrival, store properly, avoid contamination.

• If you require archival, waterproof or document?grade performance (resistant to water, chemical exposure, fade over decades) then this ink may not meet that level—it is a dye?based standard fountain?pen ink.
