kind of wine
醽 refers to a specific kind of wine. The meaning is narrow and does not extend to general wine or alcohol concepts.
醽 combines the wine radical 酉 with the phonetic component 霝, suggesting a type of wine whose name is related to the sound 霝.
The wine jar 酉 on the left and the rain-like 霝 on the right suggest a wine as clear as raindrops, a special kind of wine.
For レイ, imagine a ray of light shining through a glass of this clear wine: ray -> レイ, and the wine sparkles.
