Coffee to water ratio ~

Use 1 level tablespoon of ground coffee per cup capacity of the coffee maker for a strongish brew.

For even stronger coffee use rounded or heaped tablespoon measures.

For weaker coffee use dessert spoon measures or reduce the measure by 1 cup at a time i.e. 4 tablespoons in a 5 cup capacity coffee maker.

Ratios will vary for different coffees and, although not ideal, you can always add more fresh boiled water if the coffee turns out too strong, but you can't make a weak brew stronger.
