Hand coffee proposal is tie-in a pointer thermometer

Major factors that affect the coffee has eight: 1. 2 extraction of water temperature. Grinding degree 3. 4 extraction pressure. Powder amount 5. Crush the degree of 6. Water quality of 7. Machinery and equipment 8. People, of which temperature is one of the most important key! Temperature is very difficult to master for general machine, because of the coffee itself contains hundreds of complex material, and these substances will be extracted with different extraction temperature of different material, cause the taste of coffee is protean, suggest that coffee extraction temperature in the 90 best & deg; C ~ 92° For optimal extraction temperature between C, because if the temperature is high, will & other; Hot die & throughout; Coffee substances such as amino acids, aromatic hydrocarbon, if lower than 82 ℃, is hard to fully extract of coffee, drink coffee and the best temperature for 85 & deg; C。 Hand coffee proposal is tie-in a stainless steel pointer thermometer, the following figure.
