Wa alaykum salam wa rahmatuLlahi wa barakatuHu,

Foods containing natural and/or artificial flavors, with alcohol being used during the flavors’ production, are permissible. Liquid intoxicants are impure. Yet, flavors may be excusable according to the Shafi’i Madhhab’s principles, as it is a case of ‘umum al-balwa [public affliction]. This expressed case was not found in the Madhhab, while comparable cases establish its premise. Today, natural and artificial flavors are found in many products. Lawful items containing them are permissible; the undetectable, trace amount of alcohol contamination that occurred during their production is excusable [ma’fu ‘anhu].

And Allah knows best.
