I sometimes clean my coffee cup with this potion and it works really well. TDS differences were detected using a VST concentration meter and sensory analysis was used to establish flavor. 1. Direct water injection method: continuous water is not stuffy

Use professional detergents to clean instruments that are often in direct contact with coffee, such as handles, hand filter bowls, etc. These detergents can clean up the residual coffee grease where the water is out of reach. I sometimes use this medicine to clean coffee cups, and the effect is really good.

VST concentration meter was used to detect TDS differences and sensory analysis was used to establish 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.
