title_body: Beer Kit - How long is it good for
upvoted_answer: If everything has been sealed tightly, it should all be good still. The grain is probably fine, check that it's dry and still hard before using it, and inspect carefully for weevils or other small bugs.
  
  Dry extract is good for at least 6 months if sealed and dry. Sift it and see how clumpy it's gotten- if it's been good and dry, it won't have many clumps, and you can still use it.
  
  Liquid extract is fine for at least a year if it's sealed. Check the top of it for mold.
  
  There are many schools of thought on hops going bad- personally, I'd buy new ones. Also buy new yeast, or at least get it started a couple days ahead of time and make sure it's nice and alive.
