Hydrolats: From Analyses to Zingiber (Part 2)

What You'll Learn

  • To understand different analyses that are performed on hydrolats
  • To recognize hydrolat contamination
  • To learn about filtering, GMP, and storage of hydrolats and to read GC reports of hydrolats
  • To explore heavy metal contamination in hydrolats
  • To separate facts from assumptions
  • To discover new applications for your hydrolats


Hydrolats may be as old as distillation itself yet we know so little about them. In this course, Part 2 of Hydrolats: From Analyses to Zingiber series, we will spend time learning about the different analyses that we can use to test our hydrolats: from microbiology, GC, heavy metals, and pesticides. We will learn why each is important and how to read the reports. We will spend some more time on Good Manufacturing Practices and caring for your hydrolats. In lesson 2, we will look at basic chemistry of the hydrolats and view some comparisons from various analyses. Lesson 3 will address common misconceptions surrounding hydrolats. We will learn to use some critical thinking when it comes to separating facts and opinions. Finally, in lesson 4, we will explore some different and unique applications for your hydrolats.

Ann Harman is a distiller, organic farmer, amateur botanist and lover of plants. She lives and teaches in Washington state. Ann is an author, teacher and international speaker.

Ann began her journey with plants at an early age when she started studying the native plants and their medicinal uses in high school. She went on to study botany, and ethnobotany at Colorado State University in Fort Collins, Colorado.

Ann fell in love with distillation when she was introduced to it at a United Plant Saver’s retreat in the late 1990’s. She bought her first still after that retreat and has been distilling ever since. Ann spent many years honing her craft and in 2005 she founded Morning Myst Botanics, a company dedicated to wholesaling hydrosols distilled as a primary product. She sold the business eight years later so she could concentrate on her research of hydrosols that had become her passion.

Ann founded the Circle H Institute, a website dedicated to education, researching and promoting hydrosols. It is this website where she houses the data on hydrosols that she has been collecting for more than 25 years. She loves to share her research through the website and also through unique hands on workshops that focus on distillations. These workshops bring experts from around the globe to Spokane, WA for engaging, quality hands on experiences in the art of distillation.

In 2015 Ann self-published her first book, Harvest to Hydrosol, this book was a compilation of her workshops and shared what she has learned along the way in her distillation journey. She has found that the learning never stops and is currently writing a second edition to include what she has learned since she wrote the first edition.

When she is not distilling or gardening she enjoys riding her horses, painting and appreciating the nature that surrounds her.
