\\frac{500}{16} = 31.25 \\text{ g} \\]<\/p>\n<p>\\[ W = 31.25 \\times 16 = 500 \\text{ ml} \\]<\/p>\n<p><strong>Result:<\/strong> use 31.3 g of ground coffee (about 6.3 level tablespoons) and 500 ml of water, which yields roughly 2 cups of 250 ml.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to use the calculator<\/h2>\n<ol>\n<li>Choose your <strong>Brewing method<\/strong> \u2014 each option loads a typical coffee-to-water ratio (drip 1:16, French press 1:14, AeroPress 1:13, moka pot 1:10, cold brew 1:8, espresso 1:2). Select <em>Custom ratio<\/em> to enter your own.<\/li>\n<li>If you chose <em>Custom ratio<\/em>, enter the value in <strong>Custom ratio (1 : x)<\/strong> \u2014 the number of water parts per 1 part coffee, e.g. 16 for 1:16.<\/li>\n<li>In the <strong>I know the amount of<\/strong> field, say whether you are starting from the water you want to brew or the coffee grounds you have on hand.<\/li>\n<li>Enter the <strong>Amount<\/strong> and pick grams or ounces. Note that 1 ml of water weighs 1 g, so water volumes and weights match.<\/li>\n<li>Read your recipe below: ground coffee required, water required, and a summary table with the ratio, ounce conversions, tablespoon estimate, and number of 250 ml servings.<\/li>\n<\/ol>\n<h2>What is a coffee brewing ratio?<\/h2>\n<p>The brewing ratio is the relationship between the mass of ground coffee and the mass of water used to brew. It is written as <em>1 : x<\/em>, meaning 1 part coffee to <em>x<\/em> parts water. It is the single most important variable for consistent coffee: the same beans, grind and technique will taste dramatically different at 1:14 versus 1:18.<\/p>\n<p>A <em>stronger<\/em> brew (lower <em>x<\/em>, more coffee per litre of water) gives a heavier body and more intense flavour. A <em>weaker<\/em> brew (higher <em>x<\/em>) tastes lighter and more tea-like. Most brewing guides place balanced drip coffee between 1:15 and 1:17, while espresso is concentrated at around 1:2 and cold brew at 1:8 because it is typically diluted or served over ice.<\/p>\n<p>The result tells you exactly how much coffee and water to weigh out. Because coffee beans vary in density, weighing grounds in grams is far more reliable than counting scoops or tablespoons \u2014 the tablespoon figure in the results is only an approximation (about 5 g per level tablespoon) for when a scale is not available.<\/p>\n<p>Note that the water you put in is not the beverage you get out: grounds absorb roughly twice their weight in water, so a 500 ml brew yields about 440 ml of coffee in the cup. If you are sensitive to caffeine, keep in mind that strength also depends on when you drink it \u2014 planning your last cup around your bedtime is easy with our <a href=\"https:\/\/wpcalc.com\/en\/life\/sleep-cycle-calculator\/\">Sleep Cycle Calculator<\/a>.<\/p>\n<h2>Typical ratios by brewing method<\/h2>\n<table>\n<thead>\n<tr>\n<th>Method<\/th>\n<th>Ratio<\/th>\n<th>Character<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Drip \/ Pour-over<\/td>\n<td>1:16<\/td>\n<td>Balanced, clean, standard starting point<\/td>\n<\/tr>\n<tr>\n<td>French press<\/td>\n<td>1:14<\/td>\n<td>Full-bodied, rich immersion brew<\/td>\n<\/tr>\n<tr>\n<td>AeroPress<\/td>\n<td>1:13<\/td>\n<td>Concentrated but smooth, often diluted<\/td>\n<\/tr>\n<tr>\n<td>Moka pot<\/td>\n<td>1:10<\/td>\n<td>Strong, espresso-like stovetop coffee<\/td>\n<\/tr>\n<tr>\n<td>Cold brew<\/td>\n<td>1:8<\/td>\n<td>Concentrate, diluted with water or milk<\/td>\n<\/tr>\n<tr>\n<td>Espresso<\/td>\n<td>1:2<\/td>\n<td>Very concentrated, served in small shots<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Assumptions, limitations and tips<\/h2>\n<ul>\n<li><strong>Weights, not volumes.<\/strong> The calculator assumes water is measured by weight (1 ml = 1 g). If your kettle only shows fluid ounces, remember 1 fl oz of water is about 29.6 ml.<\/li>\n<li><strong>Ratios are starting points, not rules.<\/strong> Taste a brew and adjust by small steps: going from 1:16 to 1:15 with the same water adds about 6% more coffee, a clearly noticeable change in strength.<\/li>\n<li><strong>Grind and contact time matter too.<\/strong> A ratio cannot fix a grind that is wrong for the method \u2014 a French press needs a coarse grind, espresso a fine one. Strength in the cup depends on extraction as well as ratio.<\/li>\n<li><strong>Bean density varies.<\/strong> Dark roasts are less dense than light roasts, so a \"tablespoon\" of dark roast weighs less. The gram values from this calculator remove that guesswork.<\/li>\n<li><strong>Cold brew is a concentrate.<\/strong> At 1:8 the result is meant to be diluted roughly 1:1 with water or milk before drinking; the \"servings\" figure refers to the undiluted liquid volume.<\/li>\n<li><strong>Espresso shots are small.<\/strong> A 1:2 ratio means 18 g of coffee yields only about 36 g of beverage \u2014 enter the coffee amount you dose, not a mug volume.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Work out exactly how much ground coffee and water you need for any brew.
