The American Practical Brewer and Tanner

In Short

Published in 1815, this practical manual serves as a complete technical guide for establishing and running efficient breweries, malt houses, and tanneries in early America. Joseph Coppinger outlines structural architecture, grain cultivation, precision malting, controlled fermentation, and rapid tanning methods. He integrates contemporary chemical theories on oxygen, combustion, and decomposition to elevate everyday domestic and commercial craft into a profitable science. The work remains an intriguing artifact of early American industrial history, domestic self-sufficiency, and commercial enterprise.

The Story

The treatise opens with physical infrastructure, detailing how to construct efficient, fireproof facilities. Coppinger lays out an idealized square architectural plan for a combined brewery, malt house, and outer yard. He specifies elevated sky coolers to supply water throughout the plant and proposes novel subterranean or earth-insulated vats designed to maintain cellar temperatures above ground. From structural design, the text shifts to raw materials, emphasizing that good malt liquor requires superior grain. The author addresses the state of American agriculture, advocating for spring barley over thin winter varieties and offering detailed instructions for cultivating hops and malting alternative regional grains like Indian corn, rye, oats, and wheat.

The theoretical core of the text addresses fermentation and malting chemistry. Coppinger analyzes malt drying, citing experiments to demonstrate how excessive heat scorches sugar and releases unfermentable oils that ruin beer clarity. He frames fermentation not as a mysterious art, but as a predictable chemical process—a form of slow combustion governed by the conservation of matter. He maps out the chemical inputs and outputs of vinous, acetous, and putrefactive processes, detailing the roles of fixed air, oxygen, hydrogen, and azotic gas.

Moving from theory back to practice, the book delivers a detailed portfolio of recipes for home and commercial applications. These include table beers, shipping brews, strong ales, and specialty liquors like London-style Windsor ale, Welsh ale, and porter. Coppinger details methods for using hop extracts without boiled vegetal matter, preserving yeast for distant transport, and clarifying cloudy product using finings. The treatise then broadens into a commercial manifesto, urging American investors to form joint-stock brewing companies to replace imported English porter with domestic production. The final section transitions to the leather trade, presenting time tables and technical processes for the accelerated French method of tanning heavy sole leather, calfskins, horse hides, and goat skins.

How It Unfolds

Designing the physical plant Coppinger presents blueprints for an enclosed, fireproof brewery square featuring elevated pine water coolers and earth-rammed storage vats designed to regulate internal temperatures without expensive cellar construction.

Mastering the raw grain The author outlines agricultural guidelines for raising spring barley and hops, followed by precise temperatures and timelines for malting barley, rye, oats, and Indian corn.

Explaining the chemical science The text analyzes fermentation as a natural chemical decomposition similar to slow combustion, explaining how oxygen, fixed air, and carbon interact during the transformation of vegetable sugars.

Formulating the recipes Specific brewing schedules define exact proportions of malt, hops, yeast, and flavor additives like honey or coriander for table beers, strong ales, and dark porters.

Building American industry Coppinger argues for establishing large-scale joint-stock breweries in the United States, citing production figures from London firms to prove the profitability of domestic manufacturing.

Accelerating the tan yard The manual concludes with day-by-day logs demonstrating how new French chemical techniques tan ox hides, calfskins, and horse hides in weeks rather than months.

The People

Joseph Coppinger The author and experienced practical brewer who seeks to modernize American domestic manufacturing through applied science. He pushes past traditional rule-of-thumb methods, arguing that understanding chemistry allows producers to reduce waste, lower costs, and build profitable commercial enterprises.

David Combrune A pioneering brewing theorist whose recorded experiments in malt drying provide Coppinger with empirical proof regarding heat thresholds. His findings help establish the precise temperatures where grain germinates or chars, guiding brewers away from spoiled, scorched batches.

Count Rumford An influential scientist whose studies on heat and fuel economy inform Coppinger's architectural and chemical arguments. His work on fixed air and combustion provides the theoretical basis for optimizing energy and temperature control within kilns and fermentation vessels.

Beamish & Crawford An Irish brewing partnership whose commercial trajectory in Cork serves as Coppinger's primary case study. Their success in building a dominant porter export business demonstrates how new American ventures can capture local markets and displace foreign imports.

In Its Own Voice

"Fermentation is the instrument or means which nature employs in the decomposition of vegetable and animal bodies, or reduction of them to their original elements, or first principles."

Coppinger opens his theoretical analysis of brewing by grounding everyday fermentation in natural law.

"There is no production of the brewery more important to society than good table beer, whether it be considered as a diluent to animal food, or a diet drink in fever cases..."

The author emphasizes the social and medicinal value of light malt liquors for everyday household consumption.

"Our capacity to raise barley and hops, in as high perfection as in any part of Europe, is acknowledged; all then that is wanting is encouragement..."

Coppinger issues a patriotic call to action, urging American entrepreneurs to build domestic manufacturing capabilities.

What It's Really About

Beneath its procedural guides and ingredient ratios, the book presents a passionate argument for scientific modernization and American economic self-reliance. Coppinger seeks to demystify traditional trades by applying the discoveries of late eighteenth-century chemistry to everyday industrial processes. He views waste, spoiled batches, and inefficient methods as preventable failures caused by ignorance of natural law. By teaching readers how heat, air, and organic matter interact, he aims to transform rural trade crafts into predictable, standardized industries. The text champions domestic production as both a civil utility and a national necessity, arguing that technical knowledge will free the young republic from reliance on imported European goods.

Why Read It Today

This work offers a vivid, unvarnished window into early American industrial history, practical chemistry, and domestic life. Historians, homebrewers, and craft beverage enthusiasts will appreciate its granular details on historical recipes, grain processing, and early factory design. Coppinger’s clear, persuasive prose makes complex eighteenth-century chemical concepts accessible, capturing the optimistic spirit of an era that believed science could improve every human endeavor.

Readers should expect the stylistic conventions of 1815, including archaic spelling, period chemical terminology like "phlogisticated air," and long, complex sentence structures. Because it is an instructional manual rather than a narrative, it contains dense recipe schedules, industrial measurements, and repetitive procedural lists. Yet what remains with the reader is Coppinger's earnest dedication to craftsmanship and his vision of a self-sufficient nation built on practical knowledge and scientific discipline.
