Woodforde's Norfolk Nip

I've had this bottle of 7% beer since 2014, the last of a number I bought then. I decided to keep one to see how well it aged (though I see that it has a 'Best Before' date of October 2017! What worries me is that I haven't seen any sign that the Woodforde brewery plans to produce any more of this beer; (ie I don't think it has been brewed since 2014).
