These new jars have a three part design, the black glass UV proof jar, a leak proof plastic insert to cap the jar and then the black plastic lid. This provides a more smell resistant and air tight jar than previously.
Being made from thick UV proof black glass these jars are the best option for day to day preservation of your concentrate and long term concentrate storage. The jars have a perfectly regular mirror finish inside, the sides and base are flat, they have no internal corners for concentrate to get stuck in, only smooth rounded surfaces.
Designed to be stable these jars have a thick, wide base giving them a low centre of gravity. Another advantage of this design is that it allows for a deeper lid which provides a better seal and improved smell resistance over similar jars with shallower lids.
