Send me your thoughts at ibotezatu5@gmail.com Welcome back to The Wine Lab. In this episode, we take a closer look at Marsala, one of the most misunderstood fortified wines in the world. Often dismissed as a cooking ingredient, Marsala has a long history as a serious wine shaped by fortification, oxidative aging, and deliberate patience.

Vermouth and the Logic of Botanicals

The Wine Lab ·

2025/12/22

Send me your thoughts at ibotezatu5@gmail.com Vermouth is everywhere, yet rarely examined on its own. Often encountered through classic cocktails rather than the glass itself, vermouth plays a defining role in balance, aroma, and structure while remaining largely unacknowledged. In this episode of The Wine Lab, we slow down and treat vermouth as what it truly is: wine, shaped by fortification, bitterness, and deliberate design. We explore vermouth’s foundations in neutral grape varieties, the...

In this episode of The Wine Lab, we explore how Madeira’s unique production methods developed through long ocean voyages, how fortification with highly rectified grape spirit shapes sweetness and stability, and why heating methods like estuf...

Pét-Nat: Ancient Method, Modern Mood

The Wine Lab ·

2025/11/17

Send me your thoughts at ibotezatu5@gmail.com Before Champagne perfected the art of bubbles, there was pétillant naturel or pét-nat - the ancestral, gracefully imperfect way to make sparkling wine. In this episode of The Wine Lab, we explore the chemistry, the history, and the somewhat controlled chaos that defines this naturally effervescent style. Why does pét-nat fizz differently? What actually happens when fermentation finishes inside a sealed bottle? And why are winemakers, f...

2025/11/03

Send me your thoughts at ibotezatu5@gmail.com What makes Prosecco so different from Champagne or Cava? In this episode, Andreea takes you inside the tanks (almost literally) to explore the Charmat method, the clever bit of winemaking engineering that gives Prosecco its bright, floral personality. We’ll look at how Glera grapes, stainless-steel pressure tanks, and precise temperature control create a wine built on freshness rather than aging. You’ll learn what “tirage” and “dosage” mean...

In this episode of The Wine Lab, we explore two sparkling legends - Champagne and Cava - both born from the same meticulous process yet shaped by different lands, grapes, and histories.
