pure sake, purity, affection
醇 centers on the idea of pure, undiluted quality, originally describing rich, unadulterated sake. This extends naturally to general purity and, by metaphor, to deep, sincere affection that is untainted.
醇 combines 酉 (sake jar) with 享, which likely contributes the sound and the idea of offering or richness, together suggesting pure, rich sake.
The sake jar 酉 on the left and 享 (suggesting an offering) on the right: picture a jar of the finest, purest sake being offered, its richness representing purity and deep affection.
For ジュン, imagine a connoisseur tasting the pure sake and nodding: 'June is the perfect month for this.' June -> ジュン, and the pure sake is enjoyed in early summer.
