We conclude Regenuary with our interview with Mimi Casteel. Mimi is one of the preeminent voices for regenerative agriculture and no till, which she practices at Hope Well Vineyard in Eola-Amity Hills, Oregon. Mimi explains the advantages and disadvantages of tilling, one of which is the release of carbon into the atmosphere, contributing to climate change. She addresses what she believes are necessary changes to farming subsidies and viticultural regulations if we are to achieve a...

We continue our celebration of Regenuary with our interview with Nigel Greening, proprietor of Felton Road in Central Otago, New Zealand. Nigel discusses the role of animals in the vines and the winery’s ecosystem. Nigel explains the difference between sheep (which are grazers) versus goats (which are browsers) in managing their wild rose population. While some believe the best way to restore land is by removing grazing animals, Nigel believes the contrary--their highland cattle has...

Today, we celebrate #Regenuary with Jordan Lonborg, viticulturist of Tablas Creek. Tablas Creek farms 120 acres of Rhone varieties in Paso Robles, California. They were certified organic in 2003. They have been farming biodynamically since 2010, and received their biodynamic certification in 2017.

Today, I speak with Zach Lawless, founder of Good Goods, a bottle return program where you bring back your empty wine bottles to participating wine stores in exchange for credits towards future wine purchases. A bottle of wine’s biggest carbon footprint is the manufacturing of the glass bottle. In the Good Goods program, the bottles are reused instead of recycled--recycling a bottle saves 7% in carbon emissions whereas reusing a bottle saves 52%. Zach and I talk about his market research...

PIWIs are hybrids-varieties made by crossing 2 different Vitis species-- bred specifically for their fungus resistant capabilities. This means that they...

Today we will be broaching a subject that might make you uncomfortable--the relationship between alcohol and cancer. The reason for this discussion is personal; I was diagnosed with breast cancer this October. The causes of breast cancer are debated, but it is pretty clear that alcohol does not help. So how do I continue a life now devoted to wine? What is a suitable balance between my passion and its risks? The opinions of doctors vary considerably on the subject. Today, I welcome Amy...

In an October 2020 New York Times article, Julia Moskin shared accounts of sexual harassment and assault of 21 women at the Court of Master Sommeliers Americas. She wrote a follow up article, where the Chairman of the Court, Devon Broglie, stepped down amidst sexual misconduct allegations of his own.

We speak with grower Mathieu Lapierre from Domaine Marcel Lapierre about the use of microscopes to monitor yeasts, bacteria, and other microorganisms during vinification. He also discusses the different methods he uses when issues arise.

Today we speak to winemaker Diana Snowden Seysses about carbon capture and re-use. Carbon is essential for life. There are pure forms of carbon such as diamonds and combined forms such as CO2, which makes up the majority of greenhouse gases —around 80%. Although they are not the biggest contributors to greenhouse gases, emissions produced as a by-product of wine fermentation are 5 times more concentrated than those of cars or planes. Instead of letting this gas get released into the...

We speak to Professor Benjamin Bois from the University of Burgundy about climate change and viticulture. In Burgundy, harvesting in August is the new normal. Indeed, there have been 7 vintages with August harvest dates since 2003. However, some questions remain. How will this warming trend continue? What about rain, frost, hail, and diseases? And what about some of the proposed strategies to combat climate change such as using different varieties and rootstocks?

We speak with Joel Burt, winemaker of Las Jaras Wines, a project he shares with comedian Eric Wareheim. He discusses how winemakers deal with smoke taint, ash and soot.
