Camp Coffee, the Union Army Way of 1862

Camp coffee in a tin cup beside a dented coffee pot and grounds on brown paper, by a campfire and tent.

The story behind the recipe

Sanderson told Union company cooks to boil coffee in the kettle, settle it with a dash of cold water and pour it off through flannel. James M. Sanderson, a captain and commissary of subsistence of volunteers, set it down for the company cooks of the Army of the Potomac in a government pamphlet of January 1862: “Of all the articles of diet afforded the soldier none is more important or popular than his coffee.”

A ration, not a cup

The coffee came as an ingredient. The Army’s regulations of 1861 allowed 10 pounds of coffee and 15 pounds of sugar to every 100 rations, about 45 grams of coffee a man a day, and someone still had to roast, grind and boil it. Sanderson wanted each company to buy a small roaster, a mill and a strainer from the company fund, and to scour the kettles “with ashes and hot water.” For a whole company he measured out “so many rations of water,” plus five more “for lee-way,” so the coffee lost nothing in strength or quantity. John D. Billings, a veteran writing in 1887, remembered it less neatly: company coffee that was often poor, and men brewing their own in tin cans with wire handles.

Making it today

Sanderson gives no weight of coffee for the kettle, so the half ounce to two cups here is our choice. Ready-ground coffee stands in for his roasting and double grinding. A pan with room to spare replaces his kettle filled “very nearly to the top,” which would boil over on a stove. It is alcohol-free; add sugar at the table if you like.

Of all the articles of diet afforded the soldier none is more important or popular than his coffee. The open tin pans used for roasting it are singularly unfit, wasting, even when regularly burnt, the fragrance or aroma, which forms the chief virtue of the drink. To obtain a small roaster, coffee mill, and strainer, should be the first effort of the cook, and the best outlay of the company fund. If, however, circumstances prevent that, use what is given to the best advantage. In roasting coffee, great care must be bestowed to prevent its burning. To avoid this, some use a little fat, and others add a tablespoonful of sugar; and all stir it constantly, over a very slow fire. When well browned, cover immediately with a damp cloth, and allow it to cool; then grind it, passing it through the mill twice. The kettles in which it is to be prepared should be perfectly cleaned, and scoured inside and out with ashes and hot water, scalding them before using. The water should be fresh and perfectly clear. Fill the kettles very nearly to the top, and place them over a brisk fire to boil. Whilst boiling, throw in the coffee, which should be slightly moistened before with warm (not hot) water; and, stirring it into the water, let it boil up briskly for two minutes; then dash in a cup of cold fresh water, and take it off the fire immediately. Let it stand five minutes, to allow the grains to settle, and then pass it slowly through a flannel strainer into another kettle, from which it is served. By this mode alone can the coffee be prevented from being impregnated with the dust formed by grinding it, and make it palatable and wholesome. Whatever number of men may have to be served, measure out carefully so many rations of water, adding five for lee-way, so that it may lose nothing in strength or quantity.

Recipe notes

When adjusting quantities

Sanderson gives no ratio of coffee to water. Keep about 1/2 oz (14 g) of ground coffee to each 2 cups of finished coffee.

Notes

Quantities mentioned in these notes don’t change when you adjust the batch.

Changes from the source: the 3 tablespoons (about 14 g) of coffee, all the water amounts and the top-up to 2 cups are ours, since Sanderson gives no ratio. Store-bought ground coffee replaces his roasting (with a little fat or a spoonful of sugar to stop it burning), cooling under a damp cloth and grinding twice. Washing up replaces scouring with ashes. His “cup of cold fresh water” is for a company kettle; a tablespoon does the same job in a small pan.

His closing rule, “adding five for lee-way,” means five extra rations of water for the kettle, not five percent. He doesn’t say how much water a ration was.

The navy’s side of the ration, where the grog was halved and tea given out in 1824, is in Half the Grog and a Pint of Tea. For his tea, made in the same kind of kettle, see Camp Tea, the Union Army Way of 1862.
