This episode is a deep dive into sulfur use at the crusher, during aging and at bottling with some contestation of both commodity winemaking and natural wine. As a note, yes I do make some sulfur-free wines, yes Prima Materia definitely embraces the value proposition and ethos of "natural winemaking" or minimal intervention, and it fully condemns the marketing misinformation arm of natural wine and slavish ideologues brandishing erroneous chemistry glosses.
