The volume of air differs at different temperatures and altitudes. The juice is bottled at 920m above sea level at 5°C. The volume of the air at the top of the juice will therefore change if one or both of these variables change. This may impact the shape of the bottle slightly.  This is called “paneling”.

As soon as you open the bottle, the differences will equalise and the shape will be perfect! Just remember that as soon as you open the bottle, the impact of the HPP process (described above in point 3) stops so you need to use the juice within 8 days of opening. But once you open it to experience the taste and quality – you will definitely not wait 8 days to consume the rest!
