We have John's mother's Chemex half gallon size coffee maker. She had the copper Bain Marie bowl that we didn't know was part of the Chemex, and threw it out. I found one on Ebay, so here it is.
John's mom also saved the original 1961 instructions on how to use, and brew coffee the Chemex way. It was like reading my text book from chemistry class in high school. Every unit of measure was in grams, except for a few in ounces, and then there was liquid measure, and dry measure. The directions emphatically state that one should not use the weight measure, only the volume measure.
So, 6 ounces of ground coffee measured in a Pyrex measuring cup, plus one ounce for the pot. 36 ounces of distilled, or spring water (never tap) brought to the boiling stage. After the water is brought to a boil, let rest for 5 minutes to bring it down to the perfect temperature for brewing. Pour water over the grounds to let them bloom, then add the rest of the water slowly. I did that.
The carafe sat in the bain marie over a low flame as I poured in the hot water. It took time, thank goodness I didn't have a hangover. The result was the best, most intense coffee I've had in a long time. I even got a slight buzz from it. Is it worth it? Yes. Is it a pain in the butt? Yes.
The instructions also advertise the Chemex products of the 1960's. Coffee cups, beer glasses, cocktail glasses, and a room filtration disc called the Chemex Filterjet which has rotating paper-discs and looks like a flying saucer. The Ohmovar, which is an electric kettle, and the Teamex, Soupette, and the Ohmaire convection stove that needs no fan.
Having a fresh brewed cup of Chemex brewed coffee should be on everyones' bucket list.
