  • Cans & String

    Jim, your approach to recording these interviews can’t be the same as your wine making. Find a way to make the audio on location sound better than tin cans on a string.

Talking Points

Recent interactions between the hosts and their guests.

222: Jillian Johnson DeLeon - Laffort
Q: When is the right time to add nutrients in a native fermentation?
Early signs of life such as cap formation mark the right time to begin feeding, typically within 24 hours of pitch, or even during inoculum buildup to ensure adequate Yan for growth phase.
222: Jillian Johnson DeLeon - Laffort
Q: How should you structure the first nutrient additions (organic vs inorganic)?
The guidance favors starting with organic nutrients (NutriStart) to supply amino nitrogen, vitamins, and minerals, with inorganic additions (DAP/thiazote) used if Yan is still short after the first dose; two-dose strategy is often optimal, with one third organic and two thirds DAP in the second dose as a balanced approach.
222: Jillian Johnson DeLeon - Laffort
Q: What is Yan and how should a new winemaker think about starting nitrogen?
Yan is the sum of amino nitrogen and ammonium nitrogen; the discussion emphasizes measuring starting Yan, using two-thirds amino nitrogen to one-third ammonium as a common juice baseline, and planning additions to reach target Yan based on alcohol level and yeast strain requirements.
222: Jillian Johnson DeLeon - Laffort
Q: Before we get into that, can you share your technical background up to Laffort?
Jillian describes a path from neurobiology to winemaking through UC Davis, with hands-on harvests in Australia and South Africa, and experience in California; she emphasizes learning through internships and eventually joining Laffort in 2010.
220: Jen Williams - Arrow and Branch
Q: Tell me about the transition from a full-time job into contract winemaking and Arrow & Branch.
She describes moving to contract winemaking in 2011, handling everything from sourcing to crush space and barrels, and building a broader client base including Arrow & Branch.
