So, I've been having issues finding a suitable place to bottle carbonate my homebrew. Its been 65F or lower in my apartment since winter hit. However, I think I found the perfect place last night! There is a 4" gap between the top of my kitchen cabinets and the ceiling and temps up there are right around 75F. Perfect for carbonating my brew! However, is there any harm from storing the bottles on their sides while they pressurize? After they carbonate, they will be returning to their upright, locked position.
