Making cheese with out-of-date culture/rennet

I plan to make lots of cheese when I go 'down to the farm' and can get my 5l at the farm gate (for now, anyway... http://foodsafety.govt.nz/policy-law...ons/food-bill/)
The veg rennet's fridged and culture frozen, but they're at least a year or two out of date. Has anyone used old stuff successfully? I get the impression it's a matter of using more for the same effect, rather than the products being useless.
I'm a novice-ish cheesemaker, so 'eyeballing' worries me a bit!

Can't say as I ever have but ...WHY? Using something a day or two outdated is one thing but at least a year or more? I have made cheese and I wouldn't put in the expense, effort and time and run such a risk of having it make someone sick or be unpleasant/inedible after all. Especially if a novice cheesmaker, give yourself a break and use only the best ingredients you can,( which does NOT include ingredients "at least a year or two out of date") so as to maximize the chances of having a first class product. My opinion fwiw.

As far as I can find out, the rennet and culture won't make anyone sick, they just slowly lose potency.
I totally understand your point, but the rennet and culture are expensive and enough for waaay more cheese than I'll make, so if I buy more, I'll have the same situation again.
I'm an experienced cook, so while I haven't made much cheese, I'm ok if there's a bit of trial (and even error )
Maybe I just have get over it and buy more!

I'm more laid back than most people, but I've used out of date stuff- I just used more than was called for. You could also run a couple small test batches to see how effective they are at this point.
