# Sovereignty Module: Raise the Barrel

## Complete Coopering and Barrel Making: From Stave to Cask

Barrels store, transport, and preserve food, water, and spirits. This campaign covers stave preparation, hoop making, barrel assembly, and charring.

### Chapter 1: Barrel Types

| Type | Capacity | Use | Watertight | Difficulty |
|---|---|---|---|---|
| Tight barrel (wet cooperage) | 5-55 gallons | Liquids (water, wine, spirits) | Yes | High |
| Slack barrel (dry cooperage) | 10-55 gallons | Dry goods (flour, nails, apples) | No | Moderate |
| Bucket/pail | 1-5 gallons | Water, milk, general | Yes | Moderate |
| Tub/vat | 10-100+ gallons | Washing, fermenting, soaking | Yes | Moderate-high |
| Keg | 5-15 gallons | Beer, spirits | Yes | High |

### Chapter 2: Stave Preparation

| Step | Method | Purpose | Tools |
|---|---|---|---|
| Log selection | Straight-grained oak, 24-36 inch diameter | Quality staves | Axe, eye |
| Splitting (riving) | Froe and mallet, split along grain | Stronger than sawn staves | Froe, mallet |
| Shaping (rough) | Draw knife on shaving horse | Taper and thickness | Draw knife, shaving horse |
| Jointing | Jointer plane (long plane) | Precise edge angles | Jointer plane |
| Hollowing | Inshave (curved draw knife) | Interior curve | Inshave |
| Backing | Draw knife or plane | Exterior curve | Draw knife |
| Seasoning | Air dry 1-2 years | Reduce moisture, improve flavor | Time, sticker stack |

Stave geometry: 1) Each stave is wider at center, narrower at ends (barrel shape). 2) Edges are angled (beveled) so staves fit together in a circle. 3) The angle depends on barrel diameter and number of staves. 4) Typical barrel: 20-24 staves. 5) Each stave edge must fit perfectly against its neighbor (watertight joint). 6) Interior is slightly hollowed (concave). 7) Exterior is slightly rounded (convex). 8) Ends are thinner than center (allows bending to barrel shape).

### Chapter 3: Hoop Making

| Hoop Material | Strength | Difficulty | Durability | Traditional Use |
|---|---|---|---|---|
| Iron (flat bar) | Very high | Moderate (smithing) | Excellent | Permanent barrels |
| Hickory/ash (split) | Good | Moderate | Good (5-10 years) | Traditional, temporary |
| Steel strap | Very high | Low (if available) | Excellent | Modern |
| Willow/hazel | Moderate | Low | Fair (2-5 years) | Temporary, buckets |

Iron hoop making: 1) Forge flat iron bar (1 inch wide, 1/8 inch thick). 2) Bend to circle matching barrel diameter. 3) Overlap ends and rivet (or forge weld). 4) Make 6 hoops per barrel (2 head hoops, 2 quarter hoops, 2 bilge hoops). 5) Hoops are driven down over staves to compress and tighten.

### Chapter 4: Barrel Assembly

Assembly process: 1) Set up one head hoop (smallest diameter) on work surface. 2) Place staves inside hoop, standing upright. 3) Fit all staves into hoop (like a crown). 4) Drive head hoop down to tighten staves at one end. 5) Apply heat to open end (fire or steam). 6) Heat softens wood, allows bending. 7) Use windlass or rope to draw open end together. 8) Drive second hoop onto open end. 9) Continue heating and driving hoops until barrel takes shape. 10) Cut croze (groove) near each end for barrel head. 11) Fit barrel heads (circular discs) into croze grooves. 12) Drive final hoops into position. 13) Test for leaks (fill with water). 14) Tighten hoops if leaking.

| Assembly Step | Temperature | Duration | Critical Factor |
|---|---|---|---|
| Stave raising | Ambient | 30-60 minutes | All staves must fit in hoop |
| Bending (fire/steam) | 200-300°F | 30-60 minutes | Even heat, gradual bending |
| Hoop driving | Ambient | 15-30 minutes per hoop | Even pressure, no cracking |
| Head fitting | Ambient | 30-60 minutes | Precise fit in croze |
| Leak testing | Ambient | 24 hours | Fill with water, check all joints |

### Chapter 5: Charring and Toasting

| Level | Temperature | Duration | Color | Flavor Effect |
|---|---|---|---|---|
| Light toast | 250-300°F | 10-15 minutes | Light brown | Vanilla, coconut |
| Medium toast | 300-400°F | 15-25 minutes | Medium brown | Caramel, toffee |
| Heavy toast | 400-500°F | 25-35 minutes | Dark brown | Spice, smoke |
| Char #1 (light) | 500-600°F | 15 seconds | Black, thin | Light filtering |
| Char #2 (medium) | 500-600°F | 30 seconds | Black, medium | Moderate filtering |
| Char #3 (heavy) | 500-600°F | 55 seconds | Black, alligator skin | Heavy filtering, bourbon |
| Char #4 (deep) | 500-600°F | 60+ seconds | Deep black, cracked | Maximum filtering |

### Reference Card

1. Riving is stronger than sawing (splitting staves along the grain preserves the wood fibers intact; sawn staves cut across fibers and are weaker and more prone to leaking). 2. Every edge must be perfect (a watertight barrel depends on every stave edge fitting precisely against its neighbor; a gap of 1/32 inch will leak). 3. Heat allows bending (wood becomes flexible when heated with fire or steam; without heat, staves crack when bent to barrel shape). 4. Hoops compress the staves (driving hoops down the barrel forces staves together; tighter hoops mean a tighter barrel). 5. The croze holds the head (a groove cut near each end of the barrel receives the circular head; the head must fit precisely in the croze to seal). 6. Oak is the barrel wood (white oak is the traditional barrel wood because it is strong, splits cleanly, and its tyloses make it naturally watertight). 7. Charring creates flavor (the charred interior of a barrel filters spirits and adds vanilla, caramel, and smoke flavors; bourbon requires new charred oak barrels). 8. Season staves for one to two years (freshly split staves contain too much moisture and sap; air drying for 1-2 years produces staves that are stable and flavorful).
