The Inside Winemaking Podcast with Jim Duane Jim Duane: Winemaker, Grape-grower, and Wine Educator

Mike NuÑez - NuÑez Vineyard Management This episode features Mike Nuñez, who owns and operates Nuñez Vineyard Management, a farm labor contractor and vineyard development specialist based in Napa Valley. Mike and I discuss the barn we made wine together in back in 2004, Mike’s career path, the services that his company manages, and then an in-depth outline of how Mike plans every critical step in planning, designing, planting training, and managing a new vineyard. There’s no way we could have covered every vineyard-specific detail in one podcast, but this episode could be a resource for anyone serious about the most important aspects of vineyard development.

This episode features the return of Ben Matthews, who was a part of Episode 83 in 2018, and went on to found Terratorium, which is the focal point of conversation for this episode. Ben has been a long-time podcast listener and he and I met when he came out to Napa for the Deep Winemaking (wine camp) in 2017. A year later Ben came back to Napa to work harvest with me at Seavey Vineyard. Upon returning to Cincinnati and founding Terratorium Ben brought me into the business to help with vineyards and winemaking. 2021 was our first year of full production and the complicated path of producing our Riesling felt like a story we could share on the podcast. Our conversation covers Ben’s telling of building Terratorium, the desire to make a Riesling, Tondre Grapefield in Santa Lucia Highlands, and the many obstacles and discussions we had in order to create our desired style of Riesling. We talk through every step of the winemaking, including all of the chemistries, during this discussion.

Greg Brewer - Brewer-Clifton, Datom, and Ex Post facto This episode features Greg Brewer, founder and winemaker at Brewer-Clifton, which is a winery in Santa Barbara producing Pinot Noir and Chardonnay. Our conversation runs the gamut from Greg’s background, his experience working with grapes from Santa Rita Hills, harvest and processing logistics, my jealousy for Santa Rita’s huge picking window, DIAM corks, Greg’s stainless bin fermentors, his philosophy in sourcing a block for vineyard designated wines before planting vines, how little analytical data plays into his winemaking, the stainless Chardonnay brand Diatom, and Syrah for Ex Post Facto.

This podcast is sponsored by Flextank For nearly 20 years, winemakers in the United States and Europe have used Flextanks to make world-class wines. Flextanks have many uses in a winery including the maturation of wines. They breathe like a barrel with precise and consistent linear micro-oxygenation to your wines. The Flextank system uses its proprietary Flexstaves line of staves which are sourced from premier French and American cooperages to age both red and white wines.
Today’s technologies are playing a bigger and bigger role in wineries these days. Flextanks have a long track record of replacing traditional wood oak barrels with a revolutionary breathable polymer that is scientifically engineered to achieve Oxygen Transfer Rates similar to your choice of either a 2-year or neutral barrel. Independent scientific studies and trials have validated this technology. Unlike a barrel, however, the molecules you want to retain- like ethanol and water- do not escape the Flextank wall, which means these tanks do not lose the Angel’s share as with barrels…this means less topping is needed.
Not only do Flextanks breathe like a barrel, but they are also unbelievably simple to clean- reducing water and labor costs- and are designed in a variety of sizes and profiles to make more efficient space use in any cellar. Flextanks are built here in the United States and come with a free lifetime warranty.
To learn more about how you can modernize your winery and lower your barreling costs, simply go to Flextank.com. Discover how the Flextank system with Flexstaves is today’s new way to make award-winning wines.
