How to stir to make a good coffee
Recently, we found that many people began to add wooden sticks to the process of making hand-brewed coffee, which aroused our curiosity. Isn't it necessary to stir the coffee powder with water all the time?
When I asked this question, I decided to prove it by experiment.
According to the extraction principle, if the water and the extract are at the same temperature at the same time and the same solution is extracted under the same disturbance, we do not think that coffee will have the same result at the micro level, but a certain flavor trend can be summed up after many experiments, so we designed the following three conditions for experiments, and used VST concentration meter to detect TDS differences and sensory analysis to establish the flavor.
1. Direct water injection method: continuous water non-stuffy steam spiral water injection method
two。 Standard steaming method: steaming for 30 seconds (medium baking) or steaming for 15 seconds (deep baking) and then spiral water injection
3. Steaming and stirring method: steaming for 30 seconds (medium baking) or steaming for 15 seconds (deep roasting) and stirring with sticks for 10 seconds before continuing spiral water injection
In order to determine whether there is a positive correlation between flavor changes, we added experimental variables to test the changes of medium-roasted and deep-roasted coffee respectively.
