Why is espresso so strong?
Unlike drip coffee, which relies on gravity, espresso is made by forcing hot water through finely ground coffee using high pressure (typically 9 bars, or 130 psi! This quick extraction process—about 25-30 seconds—pulls out intense flavors, oils, and caffeine, creating that signature strong taste. The 25 to 30 Second Extraction Rule For a double shot, aim for 25 to 30 seconds of extraction to yield 35 to 40 grams of espresso, about 2 ounces. How to adjust: Grind size has the biggest impact: finer slows extraction, coarser speeds it up. Dose matters too: more coffee slows extraction.In simple terms, a 2:1 ratio means you’re extracting twice as much liquid espresso as the weight of the coffee grounds you use. For example: 18 grams of ground coffee in = 36 grams of espresso out.A shot of espresso is considered to be one (fluid) ounce, while a double shot is two (fluid) ounces. A fluid ounce is 30 mL (as opposed to an ounce by weight being 28 g). This volume refers to the espresso shot volume (water) that gets passed through the espresso.
Is espresso bad for your heart?
Unfiltered coffee, such as French press coffee and espresso, contains compounds that may raise harmful LDL cholesterol. But the effect is likely trivial compared with the rest of your diet, especially if you drink no more than two cups of unfiltered coffee daily. Conclusion: Our findings suggest that moderate coffee consumption leads to a decrease in all-cause and cardiovascular-related mortality, hypertension, cholesterol, heart failure, and atrial fibrillation. However, no conclusive relationship between coffee and coronary heart disease risk has been consistently identified.Filtered coffee has the lowest amount of unhealthy fats and highest antioxidant activity. It also filters out compounds which might increase cholesterol levels. Moderate caffeine consumption is great not only for general alertness but also for enhancing cognitive function.Drinking coffee in moderation appears to be safe for the heart. The Food and Drug Administration suggests that healthy adults can drink 4 to 5 cups of coffee without harm. Some people may be more sensitive to the effects of caffeine, depending on certain health conditions and medications.
Is it OK to drink espresso everyday?
For most adults, consuming up to 400 milligrams of caffeine daily is safe, according to the U. S. Food and Drug Administration. But if you’re enjoying espresso in excessive amounts (or any caffeinated beverage, for that matter), it might be problematic for your blood pressure. It’s rare, but a caffeine overdose can be fatal. Even if you don’t experience an overdose, regularly having unsafe levels of caffeine can damage your heart and central nervous system.Drinking too much caffeine can show up as fatigue, jitters, headaches, heart palpitations, and more. Experts recommend capping your caffeine intake at 400 milligrams a day. If you spot these warning signs, cutting back gradually and switching to caffeine-free options can help you feel better.At 2000 mg, caffeine can cause not only muscle twitches but also more dangerous symptoms, including irregular heartbeat, severe anxiety, panic attacks, tremors, nausea, vomiting, and in extreme cases, seizures or cardiac events.
