The Intersection of Lunar Phases, Wood Drying, and Meat Curing

Eben van Tonder with Carys Brynwyn, 25 November 2024

Introduction

This exploration stems from two articles published on EarthwormExpress, where we investigated historical and scientific practices around lunar phases and their application to wood cutting, drying, and meat curing. The first article, titled “Felling by the Moon: A Historical and Scientific Analysis of Lunar Forestry Practices”, analyzed how lunar cycles influence wood cutting and seasoning. The second, “Lunar Phases with Meat Cutting & Curing: A Complete Compendium”, is an attempt to mirror the foundational principles in the 1912 study on wood cutting and apply them to meat curing.

Our methodology:

1. We assumed the experience in wood cutting and drying to be factual and correct. This includes principles of moisture retention, slow drying, and optimal seasoning during specific lunar phases.

2. We compared these principles with those in meat curing to identify parallels, particularly for processes such as long-term ham curing, which historically lasted up to two years—similar to the seasoning of wood.

3. We built a compendium of meat-curing practices mapped to lunar phases, identifying optimal activities (slaughtering, salting, smoking, fermenting) and seasonal preferences (winter, summer, autumn, spring). This compendium is our effort to create a structured guide for modern practitioners, drawing heavily from traditional knowledge.

Extract from the Compendium

Based on the Lunar Meat Curing Compendium, here is a detailed breakdown of each lunar phase, its light level, traditional applications in meat processing, and the corresponding compendium entry numbers:

  1. New Moon
    • Light Level: No visible moonlight; darkest nights.
    • Application: Slaughtering animals. Minimal light is believed to reduce stress levels in livestock, resulting in tender meat with low spoilage risk.
    • Compendium Entries: 5, 6
  2. Waxing Crescent
    • Light Level: Gradual increase in light, though still minimal.
    • Application: Salting and brining meat. This phase supports moisture uptake, essential for fresh or lightly cured products.
    • Compendium Entries: 3, 4
    • First Quarter (refers to the lunar phase where the moon is exactly half-illuminated on its right side (as seen from the Northern Hemisphere) and half in shadow. Here’s the breakdown:
    • First: Indicates that this phase occurs in the first half of the lunar cycle, about a week after the New Moon.
  3. First Quarter: (The moon being one-quarter of the way through its orbit around Earth – despite appearing half-lit to us – Light Level: Half-moon visible, creating moderate light.)
    • Application: Smoking meat. Moderate moisture removal during this phase prepares meat for long-term curing.
    • Compendium Entries: 7, 8
  4. Waxing Gibbous (From the Latin gibbosus, meaning “hump-backed.” It describes the moon’s shape as more than half but less than fully illuminated)
    • Light Level: Near full moon, with significant light.
    • Application: Long-term curing of hams. Gradual moisture loss during this phase enhances texture and flavour development over extended periods.
    • Compendium Entries: 9, 10
  5. Full Moon
    • Light Level: Maximum light, creating bright nights.
    • Application: Preparing dry-aged meats. The full moon’s influence is believed to aid enzymatic breakdown, developing flavour while preserving moisture.
    • Compendium Entries: 11, 12
  6. Waning Gibbous
    • Light Level: Decreasing light.
    • Application: Fermentation or long-term brine curing. Stable moisture levels during this phase enhance microbial activity, beneficial for fermentation processes.
    • Compendium Entries: 13, 14
  7. Last Quarter
    • Light Level: Half-moon visible, but decreasing light.
    • Application: Final drying stages for products like jerky or biltong. This phase ensures shelf stability by facilitating thorough drying.
    • Compendium Entries: 15, 16
  8. Waning Crescent
    • Light Level: Minimal light as the moon approaches the new phase.
    • Application: Wood preparation for smoking. Ensuring wood is ready for smoking aligns with this phase, optimizing flavour during future curing sessions.
    • Compendium Entries: 17, 18

The Framework: Lunar Phases and Their Applications in Wood and Meat Curing

We will now apply each of these to meat curing and let’s see where we end up.

New Moon

  • Light Level: No visible moonlight; darkest nights.
  • Wood (#1): Ideal for felling trees due to reduced sap activity. Woodcut during this phase retains less initial moisture, minimizing risks of warping or cracking.
  • Meat (#1): Best for slaughtering animals. Minimal light reduces stress levels in livestock, resulting in tender meat with low spoilage risk.
  • Season: Winter. Cold temperatures align with low microbial activity, enhancing preservation for both wood and fresh meat.

Waxing Crescent

  • Light Level: Gradual increase in light, though still minimal.
  • Wood (#2): Encourages slow drying without rapid moisture loss, preserving the wood’s integrity.
  • Meat (#3): Salting and brining meat during this phase supports moisture uptake, essential for fresh or lightly cured products.
  • Season: Spring or autumn. Moderate conditions provide a balanced environment for curing.

First Quarter

  • Light Level: Half-moon visible, creating moderate light.
  • Wood (#3): Continued steady drying with increased evaporation rates. The wood begins to stabilize structurally.
  • Meat (#4): Smoking meat correlates with this phase, as moderate moisture removal prepares it for long-term curing.
  • Season: Autumn. Humidity levels are optimal for controlled smoking and curing.

Waxing Gibbous

  • Light Level: Near full moon, with significant light.
  • Wood (#4): Balanced drying conditions reduce surface tension, preventing cracks.
  • Meat (#5): Ideal for the long-term curing of hams. Gradual moisture loss enhances texture and flavor development over extended periods.
  • Season: Winter. Cool temperatures protect against spoilage while supporting slow curing.

Full Moon

  • Light Level: Maximum light, creating bright nights.
  • Wood (#5): Peak enzymatic activity improves structural properties. Controlled drying ensures minimal deformation.
  • Meat (#6): Preparing dry-aged meats benefits from the full moon’s influence, where enzymatic breakdown develops flavor while preserving moisture.
  • Season: Winter or summer. Controlled environments are essential in summer to prevent spoilage.

Waning Gibbous

  • Light Level: Decreasing light.
  • Wood (#6): Stable moisture release supports uniform drying, preparing the wood for use.
  • Meat (#7): Fermentation or long-term brine curing works well in this phase, as stable moisture levels enhance microbial activity.
  • Season: Autumn. Consistent moderate temperatures foster fermentation processes.

Last Quarter

  • Light Level: Half-moon visible, but decreasing light.
  • Wood (#7): Accelerated moisture loss prepares the wood for final use or storage.
  • Meat (#9): Final drying stages for products like jerky or biltong benefit from this phase, ensuring shelf stability.
  • Season: Summer. Warm temperatures expedite drying without freezing risks.

Waning Crescent

  • Light Level: Minimal light as the moon approaches the new phase.
  • Wood (#8): Low sap activity ensures wood is ready for smoking or seasoning, reducing moisture for clean combustion.
  • Meat (#10): Wood preparation for smoking aligns with this phase, ensuring optimal flavour during future curing sessions.
  • Season: Winter. The dormant season minimizes sap content in wood.

Bacon and Ham Curing Over One to Two Months Without Interruption

Optimal Starting Point: Lunar Phase and Season

  • Lunar Phase to Start: Waxing Crescent (#3).
    • Why: This phase supports the first critical stages: salting and brining. The increasing moisture retention aligns with the initial curing process, setting a solid foundation for flavor development and preservation. Starting here ensures the lunar cycle naturally transitions into later phases (First Quarter, Waxing Gibbous, and Full Moon) during subsequent curing, drying, and aging.
  • Season to Start: Late Winter to Early Spring (February to March in the Northern Hemisphere).
    • Why: Late Winter: Cold temperatures naturally inhibit microbial growth and allow controlled curing. Early Spring: Moderate humidity and temperatures support balanced drying without excessive dehydration.

Uninterrupted Sequence of Bacon and Ham Curing

Season: Early summer.

Salting and Brine Curing (Waxing Crescent to First Quarter)

Lunar Phase: Waxing Crescent (#3).

Duration: 7–10 days.

Why: Salt draws out moisture while the waxing moon supports moisture retention and uniform diffusion of curing agents like salt, nitrites, and sugar.

Season: Late winter. Cold weather prevents spoilage and ensures a stable environment for initial curing.

Nitrate/Nitrite Interaction (First Quarter)

Lunar Phase: First Quarter (#4).

Duration: 5–7 days.

Why: The moderate moisture activity during this phase stabilizes the cure. Nitrates slowly convert to nitrites, facilitating color and flavor development.

Season: Late winter to early spring.

Long-Term Drying and Aging (Waxing Gibbous to Full Moon)

Lunar Phase: Waxing Gibbous (#5) transitioning to Full Moon (#6).

Duration: 4–6 weeks.

Why: Gradual drying during the waxing gibbous phase supports texture development, while the full moon enhances enzymatic activity for flavor intensification.

Season: Late winter to early spring.

Final Drying and Preservation (Waning Gibbous to Last Quarter)

Lunar Phase: Waning Gibbous (#7) transitioning to Last Quarter (#9).

Duration: 2 weeks.

Why: Stable drying conditions during the waning gibbous phase finalize the curing process. The last quarter ensures shelf stability with minimal residual moisture.

Why Lunar Phases Matter

Both wood drying and meat curing rely on precise control of moisture dynamics, enzymatic activity, and environmental conditions. By aligning these processes with lunar cycles:

Wood: Seasoning becomes more predictable, reducing waste and enhancing material quality.

Meat: Traditional curing techniques gain scientific validation, improving outcomes in moisture retention, drying, and flavour development.

This project bridges ancient knowledge with modern applications, offering a holistic view of how lunar cycles influence natural processes. The resulting Lunar Meat Curing Compendium provides a practical guide, rooted in historical precedent and adapted for today’s needs. Let me know if you’d like further refinements!

Conclusion

The exploration of lunar phases in relation to wood drying and meat curing reveals a profound connection between traditional practices and natural cycles. Historically, artisans have synchronized their activities with the moon’s phases, optimizing outcomes in both wood processing and meat preservation. For instance, felling trees during the New Moon, when sap activity is minimal, results in wood with reduced moisture content, thereby decreasing the likelihood of warping or cracking. Similarly, slaughtering livestock during this phase is believed to reduce stress in animals, leading to more tender meat with a lower risk of spoilage.

These practices underscore the importance of aligning human activities with environmental rhythms. By adhering to lunar cycles, traditional methods achieve enhanced quality and sustainability in both wood and meat products. This alignment not only reflects a deep understanding of natural processes but also offers valuable insights for contemporary practices, emphasizing the enduring relevance of harmonizing with nature’s inherent patterns.
