The Official Fellow Citizen National Parks Field Collection is a two-cylinder set of freeze-dried instant specialty-grade Arabica from Papua New Guinea, designed for the cup that gets made when there is no kitchen. Shenandoah is single-origin Papua New Guinea highland coffee in pure freeze-dried form. Redwood Forest is the same Papua New Guinea highland coffee with Lion's Mane and Chaga mushroom extract added post-extraction. Both share the same origin, the same varietals, the same processing, the same tasting register, and the same field logic. Both work hot. Both work cold. Both require no grinder, no filter, no brewer, no kettle, and no heat source if cold preparation is used. Together they make up the Field Collection, a sub-registry built for the trail, the RV, the camp stove that did not start, the festival, the cabin without a coffee maker, the airport gate, the rental kitchen, and the morning that begins on the road. This article documents what each cylinder is, how the freeze-dried format preserves origin character at field weight, and how the cup gets made in the field.

What is the Field Collection?

The National Parks Field Collection is the portable arm of the Official Fellow Citizen registry. Most of the registry is whole-bean and ground twelve-ounce specialty coffee designed for a kitchen brewing setup: Chemex, French press, drip, or pour-over. The Field Collection abandons the equipment requirement. Both cylinders in the collection are freeze-dried instant. The freeze-drying step is the entire technical achievement: the coffee is brewed at the source, extracted, and then dehydrated under vacuum at low temperature into soluble crystalline form. Water is removed. The volatile aromatic compounds and the coffee oils are not. The cylinder shipped to the customer contains the coffee that was brewed at the source, minus only the water. Adding water back, hot or cold, reconstitutes the cup at the moment of serving.

This format does two things at once. First, it makes specialty-grade origin coffee portable: a 27-serving cylinder fits in a backpack pocket, weighs less than a deck of cards loaded, and survives being thrown around an RV cabinet or a glove box for months without quality loss. Second, it removes the equipment dependency entirely. There is no scenario where a Chemex, a kettle, a grinder, and a temperature-stabilized water source are available on a dawn ridge or in a campsite at 38 degrees with frozen plumbing. The Field Collection's brewing instruction is one sentence: add water, stir, drink. Hot water if available. Cold water if not. The cup that arrives is the same cup the source brewer made, reconstituted at the point of use.

The Field Collection currently contains two cylinders. Shenandoah is single-origin Papua New Guinea highland Arabica in pure freeze-dried form. Redwood Forest is the same Papua New Guinea highland Arabica with Lion's Mane and Chaga mushroom extract added post-extraction. Both are paired with American landscape paintings sourced through Wikimedia Commons under public domain rights, and both are recorded on Ethereum Mainnet at their own ENS identity anchors.

The two Field Collection cylinders

Shenandoah (Registry No. 7)

Shenandoah is single-origin Papua New Guinea Specialty Instant Coffee, freeze-dried in 27-serving cylinders at $28. The coffee is sourced from the Eastern and Western Highlands at 1,600 meters above sea level and above. Varietals are Arusha, Typica, and Bourbon. Processing is washed. The cup register is Dark Cocoa, Dried Stone Fruit, and Walnut. The painting on the cylinder is William Louis Sonntag's On the Shenandoah, ca. 1895, held at the Harvard Art Museums Fogg Museum (accession 1895.715), public domain by age (Sonntag died 1900) and sourced from Wikimedia Commons. The Harvard Art Museums Fogg Museum is not affiliated with and does not endorse Official Fellow Citizen. Shenandoah is the unmodified field cup: pure single-origin Papua New Guinea specialty coffee in instant form. The Ethereum Mainnet record lives at shenandoahcoffee.eth.

Redwood Forest (Registry No. 8)

Redwood Forest is the same Papua New Guinea highland Arabica with Lion's Mane and Chaga mushroom extract added post-extraction, freeze-dried in 27-serving cylinders at $28. Lion's Mane (Hericium erinaceus) is associated with focus and cognitive support; Chaga (Inonotus obliquus) is associated with immune support and sustained energy. Associated-with language is used deliberately. Neither is a medical claim, and Redwood Forest is not a wellness product or a health supplement. The mushroom extracts are added after the coffee has been freeze-dried into instant form, which preserves the cup's tasting register: Dark Cocoa, Dried Stone Fruit, Walnut, identical to Shenandoah. The painting on the cylinder is Albert Bierstadt's Giant Redwood Trees of California, 1874, public domain by age (Bierstadt died 1902) and sourced from Wikimedia Commons. It is not Smithsonian Open Access. The Ethereum Mainnet record lives at redwoodcoffee.eth. Companion editorial: Redwood Forest editorial post (P2N9).

The Field Kit bundle

The Field Kit packages both cylinders together at $76, a savings versus buying the cylinders individually. The Field Kit is the canonical purchase format for the Field Collection: two cylinders, one outdoor cup format, the unmodified Papua New Guinea highland Arabica register on one side, the same coffee with a mushroom layer on the other. Available at officialfellowcitizen.com/products/field-kit.

Where the field coffee comes from

Both Field Collection cylinders share the same source coffee: Papua New Guinea, Eastern and Western Highlands, 1,600 meters above sea level and above. Papua New Guinea is one of the smaller specialty Arabica producers globally, with an estimated 800,000 small-holder farmers cultivating coffee across the highland provinces. The country's coffee infrastructure is built around farmer cooperatives, certified organic and shade-grown traditions, and washed processing standardization for export. The two highland provinces (Eastern and Western) sit on volcanic and sedimentary soil at altitudes that compete with the highest-elevation specialty origins in the world.

• Origin: Papua New Guinea, Eastern and Western Highlands.
• Altitude: 1,600 meters above sea level and above.
• Varietals: Arusha, Typica, Bourbon.
• Processing: Washed.
• Format: Freeze-dried instant, 27 servings per cylinder, both products.
• Tasting notes (both products): Dark Cocoa, Dried Stone Fruit, Walnut.
• Brew methods: Hot or cold. No equipment required. No heat source required.

The freeze-drying step is what turns this origin into a field cup. The brewed coffee is flash-frozen and then placed under vacuum at low temperature; the frozen water sublimates from solid directly to vapor without passing through liquid form, leaving the coffee solids and oils intact in crystalline structure. The resulting product is shelf-stable, light, and reconstitutes cleanly in either hot or cold water. The alternative format, spray-dried instant, uses high heat to flash off water and is the dominant commercial process for mass-market instant coffee. Spray-drying degrades the volatile aromatic compounds and changes the cup register. Freeze-drying preserves them. The Dark Cocoa, Dried Stone Fruit, Walnut profile that defines this Papua New Guinea highland origin survives freeze-drying largely intact, which is why both Shenandoah and Redwood Forest hold the same tasting register as a fresh kitchen brew of the same source coffee would.

How to brew the Field Collection

Both Shenandoah and Redwood Forest brew identically. The format is freeze-dried instant. The recipe is one teaspoon (approximately 2 grams) of coffee per 8 to 12 ounces of water, hot or cold, stirred to dissolve. Below are the two preparations the format supports, and the standard field variations.

Equipment for the field

• One Field Collection cylinder (Shenandoah or Redwood Forest, 27 servings)
• A cup, an insulated bottle, or a single-wall steel mug, 8 to 12 ounces
• Water source (filtered if available; potable backcountry water otherwise)
• A spoon, twig, or shake for stirring (any clean stirrer)

Hot preparation (camp stove, kettle, or hot tap)

1. Add one serving (approximately one teaspoon, 2 grams) to the cup or insulated bottle.
2. Pour 8 to 12 ounces of hot water (just off the boil, around 200°F) over the crystals.
3. Stir for 5 to 10 seconds. The crystals dissolve fully.
4. Drink immediately or hold in an insulated bottle. Insulated holds the cup hot for the morning's first miles.

Cold preparation (no heat source required)

1. Add one serving to the cup or insulated bottle.
2. Pour 8 to 12 ounces of cold water (room temperature, refrigerator-cold, or stream-cold filtered) over the crystals.
3. Stir or shake for 15 to 30 seconds. The crystals dissolve fully in cold water with a brief stir.
4. Drink immediately or refrigerate or hold in an insulated bottle for later. Cold preparation requires no heat source.

Field variations the format supports without modification:

• Pre-charge the bottle the night before. Add the coffee to the bottle, then add water in the morning. The cylinder ships sealed; cracking the cylinder once and dosing the bottle the evening before saves cabin or tent setup time at first light.
• Add cold water to a previously hot cup. Both temperatures dissolve fully; mid-morning iced versions of a cup that started hot work without further attention.
• RV galley single-cup. The format produces a single cup of coffee per serving with no grounds, no filter, no waste stream. The galley sink stays clean.
• Backcountry weight reduction. A 27-serving cylinder weighs roughly the same as a single 12-ounce bag of whole-bean coffee, but produces 27 cups versus the kitchen brewer's roughly 25 cups per pound. The format is approximately weight-equivalent at twice the brew flexibility.

The freeze-drying step is what makes any of this possible. The coffee was brewed at source and dehydrated under vacuum at low temperature; the cup is reconstituted at the point of use. Spray-dried instant cannot do this. The Field Collection cylinders can, which is the entire reason the format is in the registry.

Frequently asked questions

What is the National Parks Field Collection?

The Field Collection is a two-cylinder freeze-dried instant specialty coffee set within the Official Fellow Citizen registry. It contains Shenandoah (single-origin Papua New Guinea highland Arabica) and Redwood Forest (the same source coffee with Lion's Mane and Chaga mushroom extract added post-extraction). Both cylinders are designed for outdoor use: the trail, the RV, the campsite, the cabin, and any setting where kitchen brewing equipment is unavailable. The Field Kit bundles both cylinders for $76.

Can the Field Collection coffees be brewed cold?

Yes. Both Shenandoah and Redwood Forest are freeze-dried instant. The crystals dissolve fully in cold water with a 15- to 30-second stir, and cold preparation requires no heat source and no equipment beyond a cup. Hot preparation uses just-off-the-boil water at approximately 200°F. Both preparations preserve the Dark Cocoa, Dried Stone Fruit, and Walnut register equally.

Is freeze-dried instant coffee specialty grade?

The source coffee in both Field Collection cylinders is specialty-grade Arabica from Papua New Guinea's Eastern and Western Highlands at 1,600 meters above sea level and above. Specialty-grade refers to the source coffee selection. Freeze-drying preserves origin character because the water is removed at low temperature under vacuum, leaving the volatile aromatic compounds and coffee oils intact in crystalline form. Spray-dried instant, the dominant commercial process for mass-market instant, uses high heat that degrades these compounds; the Field Collection coffees are not spray-dried.

What is the difference between Shenandoah and Redwood Forest?

Same source coffee. Different finishing layer. Shenandoah is pure Papua New Guinea highland specialty Arabica freeze-dried into instant form. Redwood Forest is the same coffee with Lion's Mane and Chaga mushroom extract added post-extraction. The mushroom extracts in Redwood Forest are associated with focus and cognitive support (Lion's Mane) and immune support and sustained energy (Chaga); no medical claim is made, and Redwood Forest is not a wellness product or a health supplement. The cup register (Dark Cocoa, Dried Stone Fruit, Walnut) is identical for both products.

How long does a cylinder last?

Each cylinder contains 27 servings. A single-cup-per-day rhythm exhausts a cylinder in roughly four weeks; a two-cup-per-day rhythm in two weeks. The Field Kit's two-cylinder bundle covers approximately seven to eight weeks of single-cup use, or four weeks of two-cup use. Cylinders are shelf-stable and store cleanly in any field condition between freezing and roughly 80°F; they tolerate the temperature swings of a closed RV cabin or a glove box without quality loss within reasonable limits.

How are the Field Collection coffees lab tested?

Both Shenandoah and Redwood Forest are independently lab tested by FoodChain ID, a PJLA-accredited and ILAC-MRA recognized laboratory, for mycotoxins, heavy metals, mold, yeast, and contaminants, with all compounds returning Not Detected on the finished product. Lab records are available on the Lab Results page.

What paintings are on the Field Collection cylinders?

Shenandoah: William Louis Sonntag, On the Shenandoah, ca. 1895, held at the Harvard Art Museums Fogg Museum (accession 1895.715), public domain by age (Sonntag died 1900), sourced via Wikimedia Commons. Redwood Forest: Albert Bierstadt, Giant Redwood Trees of California, 1874, public domain by age (Bierstadt died 1902), sourced via Wikimedia Commons. Neither painting is held in the Smithsonian Open Access program.

What does it mean that the Field Collection coffees are recorded on Ethereum Mainnet?

Each coffee in the Official Fellow Citizen registry has its own ENS identity anchor on Ethereum Mainnet. Shenandoah lives at shenandoahcoffee.eth; Redwood Forest lives at redwoodcoffee.eth. The registry authority is officialfellowcitizen.eth. The ENS layer is institutional record, not investment language.
