Generally speaking about RED wine and with measures taken to prevent breakage.
1. I am concerned about current practices by online wine retailers and how they ship while maintaining quality over a - wine.
2. Wine has an optimum temperature. Does shipping via a courier service within the same country spoil the wine?
3. Any issues with water vapour when using courier services?
4. Any concerns with heat?
5. What are the practices by the current biggest online wine retailer?
6. Is there a maximum period the wine is advised to remain in transit via the courier service before beginning to change quality?
