The Science of Coffee Extraction

To see why re-using a puck is problematical, you must seem at how espresso is made. When pressurized water hits a bed of fine ground coffee, it doesn't excerpt everything at once. Alternatively, it pulls out different compound in a specific episode. First, the acids are educe, follow by the sugars, and finally, the bitter tannin and flora fibre.

Phase 1: The First Pull

During the initial descent, you are drive to get the balance of acidity, sweetness, and body. A successful extraction stops incisively when you have attain this equilibrium. By the time the shot is accomplished, the coffee curtilage have already surrendered their most soluble and flavorful compounds. What remain in the portafilter is fundamentally the frame of the coffee bean.

Phase 2: The Second Pull

If you adjudicate to run h2o through the same puck a second time, you are basically "over-extracting." Since the volatile redolent oil, dough, and pleasant acids have already been rinse aside, the hot h2o is forced to extract the harsh, astringent, and bitter compound that were intended to remain in the grounds. The lead liquid is unremarkably reeking, highly bitter, and entirely miss in the characteristic crema that make espresso special.

Espresso machine operate under high pressure - typically 9 bars - which requires a precise, uniform impedance from the coffee bed. Erst a puck has been used, its structure is compromise. The curtilage have expand, engrossed h2o, and collapsed. This odd concentration leads to transfer, where water notice the route of least resistivity through the puck, resulting in an still more wandering and unpleasant sapidity profile.

Unfortunately, no. Erst the sugars and oil are educe, there is no physical operation that can bring those flavors second out of the fatigued grounds.

Will re-using the grounds preserve me money on caffeine?

Most of the caffein is extracted during the first 20 to 30 seconds of the pull. Using the yard a 2d time will return trifling caffein grade and a very pitiful discernment.

Can I use spent espresso curtilage for cold brew?

No. Cold brew relies on the flavor potential of refreshing, unextracted grounds. Spent curtilage have already had their relish potential withdraw, so a cold brewage made from them would be essentially bitter, browned h2o.

Does the machine get damage by pulling a 2nd shot?
