When to Use Each Bottle Size

Each wine bottle size has its own best use depending on the occasion and how many people you're serving.

Mini (187 ml): Ideal for individual servings, gift sets, or travel.
Half (375 ml): Great for couples, tasting flights, or lighter drinkers.
Standard (750 ml): Your go-to bottle for regular use or small groups.
Magnum (1.5L): Best for larger gatherings, weddings, or aging fine wines—larger bottles age wine more slowly and evenly.
