It’s time to grab life by the stem with Casleah!

Casleah Herwaldt is pushing the limit on some old world constraints to bring joy and knowledge to new world wine consumers.” – Monarch Wine

I’ll be your personal sommelier!


Welcome to By The Stem!

I’m Casleah, a Certified Sommelier with a vast array of experiences in the wine industry. I’ve worked as a floor sommelier for a Michelin Star chef, hosted sold out events throughout the Napa Valley, I’ve been a Brand Ambassador for a New Zealand winery and even created my own wine label. I received the top score when I completed my sommelier certification through the Court of Master Sommelier (CMS) and completed level 3 of Wine and Spirit Education Trust (WSET). I am currently in the Diploma program (level 4, the highest level).

Growing up around a vineyard, wine became an everyday part of my life! I’ve always loved strolling through the vines and spending afternoons in the local wine shops. I certainly never expected to shift from healthcare into a full time career pursuing wine dreams, but look how fun life is; throwing me the unexpected and wonderful.

I want to make wine fun, approachable and exciting for everyone! I’m always on the look out for new winery discoveries and the latest trends in the wine world! I love planning wine events and presenting private in home and virtual wine tastings. 

But what I love the most about sharing By The Stem with you, is celebrating life, providing education that inspires and the opportunity to spread positivity! From hosting your co-workers for a tasting, to curating my very own wine label, I’m thrilled to be able to share my passion with you. I offer unique experiences that you won’t find anywhere else.



For thousands of years, wine has brought people together, yet, at the same time, wine can be very intimidating and can make people feel inadequate if they don’t know something. The truth is, wine education is a lifelong journey and we are all learning along the way.

My tastings are fun, educational and interactive.

 “Casleah is extremely knowledgeable about global wines and varietals, but it is her sense of humor, effervescence and ease at presenting to a group that has made me a repeat customer.” – Liisa
