If its made before 2009 its likely not BPA free and you should consider upgrading to a modern one. I think the plastic was changed again around 2014. Mine is from that time period and doesnt have an after taste either.
As well as the glass one you can get one made of tritan, which would be my pick over the glass as its mostly the same look, a lot cheaper, and pretty much unbreakable.
