A wine meant to mature needs a constant cool temperature, the right humidity, and protection from light and vibration. A flat rarely offers these conditions reliably, so the wine may not mature the way it should.
In My Cellarium, collectors buy selected wines from Hungarian partner wineries online. The bottles stay at the winery in proper conditions, and each one gets its own identifier that can be followed in the app. With one tap a bottle can be delivered, sent as a gift or later sold on the marketplace.
My Cellarium is available on mobile and on the web, and it keeps evolving.
