However there’s a advantageous line between pleasantly bitter espresso and a cup that makes you wince with each gulp.

So… what in case your home-brewed espresso continuously falls within the latter class? “Effectively, that’s clearly when we’ve got an issue,” says Han.

If, for instance, you’re utilizing an computerized drip machine or pour-over brewer, she recommends utilizing a 1:16 brewing ratio, “that means for each gram of espresso, you’ll have to brew with 16 occasions that quantity in water.”

Are you utilizing the best grind measurement to your brewing methodology?

One other factor you need to contemplate is utilizing the best grind measurement to your brewing methodology. “Every methodology of espresso brewing requires a distinct optimum grind measurement,” says Han. “For instance, the appropriate grind measurement for an computerized drip machine might be too advantageous in the event you used that very same grind for a French press.” She recommends beginning with a medium to medium-fine grind (the grain ought to be wherever between the dimensions of kosher salt and desk salt), and in the event you’re utilizing a French press choosing a coarser grind.

No matter which at-home brewing methodology you utilize, Han suggests shopping for whole-bean espresso and grinding it simply earlier than use, which she says ends in the best-tasting espresso.

Whereas these are essential issues to remember, in the event you’d relatively sleepwalk via your morning coffee-making ritual (we see you!), you may need to decide to make use of a French press, which Han says is the only and most forgiving brewing methodology. “French presses typically use a coarser grind than different strategies, so [beans] are tougher to grind too advantageous,” she says. “Over-agitating can also be not a problem since a French press brews by steeping.” The one-trade off to utilizing a French press is that some folks may not been eager on the “muddiness” of French press espresso.

Should you’ve adopted all these tricks to a T and nonetheless find yourself with bitter espresso, don’t attain for extra sweetener simply but.
