Following Val's instructions, Adrien mixed the Wine of Wakefulness. In spite of the simplicity of the recipe, he needed some time to reach the right state of mind to be able to make it - just like the time he took for himself before each day of practicing spells. At one point, he felt like something had become different about the mixture of water and coffee that he had been whirling in the bowl for a while, and so he proceeded to bottle his first potion.
"Now what? Am I supposed to drink it, or...?".
"Oh, no, no", Val smiled. "I have a potion tester for that".
