Green and Herbal Modifiers: Study Guide

Read our guide to green notes, then use a powerful green material as a modifier: ladder it into a floral at very low levels and find where it adds realism.

Intermediate 20 min study By the RUŌOD Lab team Updated

In short

Green and herbal materials bring realism, bitterness and air to an accord, and they are usually strong enough that the question is how little to use. The reference guides cover the family. This guide practices the technique that matters most: dosing a powerful modifier by ladder.

What you will learn

  • Describe the range of green and herbal effects
  • Use a strong modifier by ladder at low dose

Before this lesson: Citrus Accord Workshop

What to look for as you read

  • The range from cut grass to sap to galbanum's bitter green.
  • How herbal materials differ from green ones, using the aromatic notes guide.
  • Which of these you could add to a floral without overwhelming it.

Practical exercise: Ladder a green note into a floral

About 30 minutes · You will have: a low-dose ladder of one green material in one of your floral accords

  1. Take your rose or jasmine accord from an earlier workshop.
  2. Prepare cis-3-hexenol or galbanum oil as a 1% or 0.1% stock.
  3. Ladder it at 0.1%, 0.5% and 2% of the accord's pure material, calculating as in the jasmine workshop.
  4. Compare with the unmodified accord. Note the dose where you sense freshness without naming the material, and the dose where it takes over.

You have done this well if you can report those two doses, even if they are approximate.

Knowledge check

1. Why are many green materials used as low-dose modifiers?
Show the answer

They are very strong and turn harsh quickly. Materials such as cis-3-hexenol and galbanum are strong, so small doses already change an accord.

2. Which material is a classic cut-grass reference?
Show the answer

cis-3-Hexenol. cis-3-Hexenol is sometimes called leaf alcohol because it reads as cut grass.

3. What does a modifier do?
Show the answer

Changes the character of an accord without being the main thing you smell. Ideally you notice its effect and not the material itself, at least at the right dose.
