Here's a logo for your consideration and fits the brief you require.
1. Martini related
2. Credible shopping source - "PROFESSIONAL"
3. Mature (35+) - No gimmicks
4. Established - Mid to upper income clients
5. Retro feel - But modern at the same time
6. Strong, Solid colors - Grey represents intelligence, modesty, practicality, conservative and maturity. While Red suggests passion (in your products), strength and vitality. It also grabs attention.
Hope you like, any further revisions or tweaks can be made at your request!
