You'll need to make sure that they are made out of the same material as Better Bottles. Most water bottles in the US are made out of a type of plastic that is not suitable as a fermentation vessel.durak said:Office spring water dispensers use 5 gallon plastic bottles. Eden springs etc. Have been meaning to contact them myself and ask if they could be purchased.
+1 on this info...Look on the bottom.KiltLifter said:Look on the bottom of the bottle you are considering. The Better Bottles are PET. Water bottles from one company around here are PET and that's what I use. I looked at one (with a molded in handle) at Home Depot and it was NOT PET, so be sure to look.
PET IS oxygen permeable, but the Better Bottle and other PET water bottles are thick enough that the permeation is negligible for the amount of time the beer is in it.
For a mead or barley wine that is in the carboy for months, I use glass, just in case.
Oxidation risk. The PET that Better Bottles are made out of has negligible gas permeability, so they're a suitable alternative to glass for medium- to long-term aging. Since water storage and dispensing doesn't have to worry about gas permeability the containers used are often made of a more permeable plastic, making them unsuitable for anything other than short-term storage of liquids where oxidation is an issue.durak said:How so? They hold the water for extended periods of time, why wouldn' they hold fermenting beer?
I have been emailing with Beertech.padair said:Back on topic - I just checked and Beertech have the 23 litre Better Bottle in stock, though they're £11.99 - shipping will depend on how many you order, but it's £9.00 to ship one and £36 to ship 2
They only have 2 in stock so if you are thinking of buying them, place 2 seperate orders.
According to xe.com £1.00 = 9.85DKK = US$1.94
