This may be an ocd question but... I have varying head space in my bottles after bottling...due to settling I believe. Some bottles have almost no space between the bottle and the wine. Some have an inch. I read ideally that it should be 3/4 inch space for temp fluctuations. But does a quarter inch to 1/2 inch variation each way matter that much? All of them have the wine crossing the shoulder to the neck. Some stop there and some go all the way to the cork, I would saying ranging from 1/4 space to 1 1/4 inch space. Am I obsessing too much. I need these bottles to last 18 months for a family event.
