I was given this as a present by someone who perhaps did not notice the word "refill". I have no kit to refill hence this post.
BUT having had this for some time, the Best Before date has been and gone (1/23). I don't take much notice of these dates myself as my own personal BB date passed a long time ago, some say a very long time ago.
So if there are still any home brewers out there, are you feeling lucky?, make my IPA.
