wa alaykum salam wa rahmatuLlahi wa barakatuHu,

In Mughni al-Muhtaj v. 5, p. 517, Khatib Shirbini mentioned a comparable situation, and stated,

لأن عين الخمر أكلتها النار وبقي الخبز نجسا

“…as the substance of alcohol is consumed by fire; the bread remains impure.”

Fire/cooking does not remove impurity, and the Shafi’i School considers alcohol, like beer, impure. Therefore, even when cooking removes all the alcohol, contamination with the impurity makes eating it problematic.

And Allah knows best.
