G'day Nathan,

There isnt any specific product info relating to this, but i have found the following on Google which sheds some light on it!

HDPE (Polyethelyne) is considered a low-hazard plastic and has a lower risk of leaching....This type of plastic is very hard-wearing and does not break down under exposure to sunlight or extremes of heating or freezing.

Based on this I would have thought it'd be ok, but recommend doing some more research or checking in with your local homebrew supply store before making a decision.

G'day G,

I've spoken to the supplier who has advised that these jerries are Food Grade, BPA Free plastic.  Hope that helps!

G'day Ed,

If you stack two of the Natural Water Cubes on top of each other then they would tip due to the placement of the lid. It is best to store these side by side.

G'day Gavin, 

The MB Agencies Natural Cube 25L doesn't come with a tap, it just comes with a bung and pressure relief cap.
