I'd Love To Be Your Personal Sommelier!

Meet Casleah

Hello everyone! I'm Casleah Herwaldt, and I am a lover of wine!
My passion for wine began early in life and has steadily transformed into a full time career!
I hold a Sommelier Certification through the Court of Master Sommelier (CMS), I have completed Level 3 of Wine and Spirit Education Trust (WSET) and am currently in Level 4 of the Diploma program! I have so much fun exploring the world of wine and I want to make the same knowledge I'm gaining accessible and less intimidating to others.
I love to educate anyone who has an interest and I love that every bottle has a story! Through By The Stem Tastings, my Wine Club, and the Casleah Wine label, I'm striving to create an environment of positivity and a community to feel welcomed to learn! I want to inspire people to try new things and experiences, but most importantly I hope to inspire you to find your passion and pursue your dreams, just as I have done through wine!

More about me

“I can’t recommend By the Stem’s wine tasting experience enough! I booked By the Stem for a corporate event, and Casleah was able to accommodate 25 people based in cities from coast to coast, managing the full process of procurement and delivery to each household seamlessly. The wine tasting was SO MUCH FUN! Casleah balances information with interactivity well. She is an incredibly knowledgeable yet vivacious host — by the end, we felt like Casleah was not only a talented sommelier but also a new friend who helped us engage with our clients in a way we never thought possible. Huge thanks to Casleah! Can’t wait for our next event!”

“During the evolving times of COVID-19 Casleah has shifted to hosting virtual wine tasting events, and they’ve been just as amazing as in-person! I’ve now hosted two separate virtual wine tastings with my clients, and Casleah has blown me away both times. She’s captivating, incredibly knowledgable, and is great at getting everyone in the group involved and participating. My clients were all very impressed and all noted afterwards how much fun they had (and how tasty the wine was). Would absolutely recommend the experience to anyone who loves wine and wants to learn more about it in the comforts of their own home!"

“Casleah and her virtual wine tastings have been the most important client meeting solution for celebrating wins, building relationships and spending time virtually with my team and customers. I love her passion for wines, growing regions and her positive energy is contagious. She is extremely knowledgeable about global wines and varietals, but it is her sense of humor, effervescence and ease at presenting to a group over video conference that has made me a repeat customer. She takes all the stress out of having a virtual meeting and makes it so much fun to smell, swirl and sip the delicious wines she chooses for each tasting. She is a true professional and a delight to work with.”
