 From royal courts in 17th-century France to today’s celebrations around the world, sparkling wine has captured attention for centuries. In this episode of The Wine Lab, host Andreea Botezatu explains how sparkling wines are made, from traditional Champagne techniques to Prosecco’s Charmat method and beyond. We’ll look at the role of secondary fermentation, explore different sweetness levels, highlight the major regions producing sparkling wine, and share the story of La Veuve Clicquot, the woman who changed sparkling wine production forever.

In this episode of The Wine Lab, we explore the unseen world of yeast—the microscopic winemakers transforming grape juice into wine. 

From lab-selected commercial strains to wild, spontaneous fermentations and even wineries culturing their own native yeasts, we uncover how these tiny organisms shape wine’s flavor, texture, and identity. 

Along the way, we touch on yeast’s long history in human culture—from bread to beer to Bordeaux.

Why does a glass of wine smell like blackberries, jasmine, or freshly cut herbs—when it’s made entirely from grapes? 

In this episode, we explore the complex and fascinating science of wine aroma.

 From compounds naturally found in grapes and flowers to the transformative role of fermentation and microbes, we trace how scent molecules form, evolve, and interact with our senses. 

We’ll also examine how genetics, memory, and culture shape the way we experience wine, and why no two noses interpret it quite the same way.

In this episode of The Wine Lab, we swirl through the science of malolactic fermentation (MLF), the process that can soften wine and elevate complexity, but also invite spoilage and instability, especially in high pH wines. We break down what MLF actually is, why winemakers use it, when they avoid it, and how to manage its benefits and risks with precision.

Perfect for winemakers, wine students, and curious wine lovers.

Can a splash of sour grape juice make wines better in a warming world? 

In this episode, we explore how verjus—juice from unripe grapes—can improve wine chemistry, reduce alcohol, and enhance sustainability in hot-climate winemaking. Based on research from Texas A&M University.

Can fewer grapes mean better wine? In this episode of The Wine Lab, Dr. Andreea Botezatu explores the science behind cluster thinning, a time-honored but hotly debated vineyard practice. Drawing from a recent narrative systematic review, we break down what the research really says about its impact on wine aroma, phenolics, sensory quality, and economic viability. Whether you’re managing a vineyard or just love wine science, this episode offers practical insights to help you make informed decisions.

We’ve all heard of “corked” wine — but what if that wet dog smell isn’t the cork’s fault at all? In this episode of The Wine Lab, we explore the fascinating and frustrating world of haloanisoles: TCA, TBA, TeCA, PCA, and their highly aromatic footprint in wine.

These powerful compounds can travel through the air, cling to barrels and insulation, and even sabotage stainless steel tanks. Learn about their origins, their impact on sensory perception, the limits of closures like screwcaps and synthetic corks, and the cutting-edge methods being developed to detect and remove them.

Whether you’re a winemaker, sommelier, or just a curious wine geek, this episode uncorks the real story behind “cork taint” — and why it’s time to call it haloanisole taint.
