Question for the no-sanitisers. Do you sanitise the inside of your bottles? If so, why are you happy with 99% sanitised containiers?
Good questions. First, the bacteria are on the lid, and they don't fly or crawl by themselves. So, if I ensure (by reasonably careful handling) that the beer in the bottle doesn't come into contact with the lid, it is unlikely to cause an infection. Now inevitably, between bottling and drinking, sometimes beer does come into contact with the lid, but usually not before the yeast in the bottle have had a good crack at the priming sugar, so the risk there is low.
The main risk, I guess, if from bacteria that can digest the ogliosaccharides (short chains of sugars) that the yeast cannot. I have had bottles explode, so I can't rule out the theory, but I'd back that I hadn't cleaned the bottles well enough in the first place - a much more likely scenario since I salvage most of my bottles from cafe/restaurant recycling bins.
