While we are on the subject of bottles I need to know the common practice for prepping bottles (cleaning/sterilizing) as this will be my first time using wine bottles.
You may see a common saying, "ask a question of 10 winemakers, and you'll get 11 opinions". With regard to bottle care, the 11 jumps to at least 35 ....
For commercial bottles, I soak in hot tap water and Oxyclean, which generally removes 3/4 of the labels. Some have a plastic or metallic backing, and peel off neatly when hot water softens the glue. Others require scraping, and I use Goo Gone to remove any remaining glue.
My bottles also get soaked briefly in Oxyclean, and the labels come off easily.
I air dry on a bottle rack, and put them mouth down in clean cases after visually inspecting for foreign matter. Rejected bottles go back through the cleaning cycle and may get bottle brush treatment.
Bottling day, I pull the bottles out of the cases and visually inspect before lining them up. I do not sanitize at that time -- as noted above, commercial wineries generally transfer bottles from boxes to the bottling line with no treatment. My bottles were clean, dry, and mouth down, so nothing can get in.
Most folks sanitize at bottling time, and that causes no problem. Folks get nervous about the bubbles remaining from Star San, but reliable information from the vendor says that is harmless and may be ignored.
