Brewing Instructions

Cona brewing is a wonderful visual experience that just happens to result in perfect coffee. While these instructions may make it sound like it might require too much time and dedication, after several times you will find it is only slightly more laborious than other brewing methods, but much more fun!


  • Fill the spirit lamp with "methylated spirits". This is commonly sold in hardware stores, paint stores, camp stores, marine supply stores, and gourmet food stores. It is also called "camp stove alcohol"or "denatured alcohol". 
  • Place the wick and wickholder in position. Allow some time for the wick to absorb fuel. (You get about 6-8 uses from one filling of the lamp, so you are not having to deal with the fuel every time you brew!)
  • Put the spirit lamp in place and the funnel (top glass globe) in its aperture on the stand. Fill the bowl (bottom globe with handle) with hot or boiling water to within about 1/2 inch from the base of the neck. Make sure the outside of the bowl is dry. (Note: you can start with cold water -the process will take much longer though)
  • Place the glass drainer (the filter) into the funnel , making sure it is loose. Put the required amount of evenly gound medium to fine coffee (--fine but WITHOUT powder!--) into the funnel. Standard SCAA brewing ratio is 7.25 grams per 5 oz water which = approximately 2 rounded (not heaping) tablespoons per 6 oz water. You can use the same fine, even grounds for filter coffee in the Cona without producing any sludge in the cup. If you chose to use coarser grinds, compensate by allowing a full 3 minutes infusion when the coffee and water are together in the funnel.
  • Light up!
  • When the water in the bowl shows the very first sign of coming to a boil, place the funnel into the bowl and snug the rubber gasket into the bowl neck with a small twist to ensure an air-tight fit.
  • When all the water, with the exception of a small amount which must remain in the bowl, has been drawn into the top, wait 1-3 minutes for the coffee to infuse. Some people like to give it a stir with a spoon. If so, don't bump and dislodge the drainer / filter.
  • Place the snuffer on the lamp.
  • When all the coffee has drained into the bowl, remove the funnel with a slight twist. Place it in the aperture on the stand, serve up your wonderful coffee ...you earned it!
