I have huge ullage (up to 2cm, or almost an inch) differences in bottles (same case) from the screwed up shipment.
yixin,
1. How do you know that the ullage differences didn't precede the screw-up with the shipment? I've had significant ullage differences within a single case that suffered no mistreatment.
2. Even if the ullage is due to the screw-up with the shipment, you're missing a link to tie ullage, instead of heat exposure, with oxidation. I've had many wonderful bottles that were seriously ullaged and I've had many bottles with no ullage whatsoever that had oxidized.
Claude,
1. I am the importer. We track the temperature and humidity from cellar to client. I go to the port to 'aid' my haulier (trucker) through the clearance process. I am present at every unstuffing of our containers at the bonded warehouse. I pay for a reefer truck even for a 15 minute delivery. So, in this instance, unless all the vignerons (11 of them in this 20 footer) conspired to have issues with their bottling line and then let those bottles through, I think it's safe to say that the ullage as well as dried residue on the bottles were caused by heat exposure.
2. I don't think I wrote that ullage caused oxidation, but perhaps my writing was unclear. What I wanted to convey was that heat damage affects bottles, even within the same case, very differently. This could show up as ullage, as colour differences, as oxidation, etc.
To be tedious - I've had heat affect adjacent bottles within the same case very differently. I don't know why, but my observations are as such.
