How long will Comfrey Liquid Feed last?

I have some that was made last year (1/2 a water butt). It no longer smells bad, but looks just the same as when it was made. Its been outside, covered with fleece.

How long will it be good to use? and its it worth adding to it this year or starting again?

No idea if it's still good, but I can't figure why it wouldn't. I'd use it and still make a fresh batch for this year, just in case.

I made some last year also nettle tea and manure soup, (don't know correct wording but you know what I mean!) . I will be using it this year and then making fresh. I use old fertiliser buckets

Thats good news... I am going to use some in the compost pile to kick it into action.  The rest will be feeding my tomatoes and peppers  .. until a new batch is ready.
