Yield depends mostly on <g id=\"gid_1\">freshness, grinding and roasting<\/g>, not on the substrate material. Look for certifications such as <g id=\"gid_2\">EN 13432<\/g> or <g id=\"gid_3\">OK compost<\/g> and check if compostability is <g id=\"gid_4\">industrial<\/g> (in plant) or <g id=\"gid_5\">domestic<\/g>. Keep the packages in a cool, dry place (15-25 \u00b0C) and open the sachet <g id=\"gid_6\">only at the time<\/g>: oxygen is the real enemy of flavorings. If you notice drop in cream or fragrance, try a newer batch or reduce the cup volume by 3-5 ml.    <\/p>\n\n<p><strong>How can I tell if my machine is really ESE compatible<\/strong>?<br\/>Check the <strong>manual<\/strong>: it should say &#8220;ESE 44 mm waffle compatible&#8221; or indicate an <strong>ESE portafilter\/insert<\/strong>. Observe the basket: for waffles it is <g id=\"gid_3\">flat<\/g> with dedicated grid (different from the one for pressed ground coffee). Do a test: the wafer should lodge centered and the <g id=\"gid_4\">closing of<\/g> the arm should be sharp, without abnormal strain; in dispensing the flow should be <g id=\"gid_5\">continuous<\/g> (20-30 s for ~25-30 ml). If you are using a manual\/semiautomatic, check if there is an original or compatible <g id=\"gid_6\">ESE kit<\/g>. If in doubt, send the manufacturer <strong>model + photos of the filter holder<\/strong>: they will confirm compatibility.    <\/p>\n\n<p><strong>How much does water affect the outcome<\/strong>?<br\/>A lot: water that is too hard flattens flavor, cream and sweetness; water that is too sweet can accentuate acidity and thinness. A practical range is <strong>TDS 80-120 ppm<\/strong> and hardness around <strong>3-6 \u00b0dH<\/strong>. If you don&#8217;t have a filter, you can use bottled water with a medium profile (avoid extremes) or mix tap and low-mineral water. Remember <g id=\"gid_3\">descaling<\/g>: every 1-3 months, depending on local hardness and frequency of use. Tank and circuit should be rinsed often: <strong>stagnant<\/strong> water alters taste and odor.    <\/p>\n\n<p><strong>Can I make cappuccinos with ESE pods<\/strong>?<br\/>Yes: choose <strong>more intense blends<\/strong> or with a <strong>Robusta<\/strong> component to maintain body and flavor under milk. Make a <g id=\"gid_3\">short<\/g> espresso (20-25 ml) to concentrate flavor and crema. Whip the milk at <g id=\"gid_4\">60-65 \u00b0C<\/g>: above 70 \u00b0C you lose sweetness and risk cooked notes. If the drink is weak, increase the intensity of the pod or reduce the espresso volume slightly. For balance in the cup, use guideline ratios of <strong>1:2-1:3<\/strong> (espresso:milk) and pour immediately to avoid losing texture.    <\/p>\n","protected":false},"excerpt":{"rendered":"<p>When a 44 mm ESE wafer does not yield as it should, the cause is almost always a combination of extraction, machine or storage.
