Or it could be like Polyjuice, which evidently can be cooked up to a point
and then left to simmer. There's definite steps to get it "ready" for a
portion of whoever you're turning into, but it can apparently stay at the
"ready" stage for quite a while. Reasoning:
--It only lasts an hour (the effects); Crouch would need fresh batches
rather a lot.
--The real Moody was kept alive for the harvesting of hair periodically (and
it must have been periodically, or Crouch would just have killed him after
he brewed up X gallons of polyjuice, or simply kept his hair)
---Snape's office was only broken into once for boomslang skin.

So Crouch probably brewed up a cauldronful, to the "ready" point, and then
scooped some out and adds Moody hair to make the active potion every so
often.

Since it is implied that this is how Polyjuice works, I have no problem
thinking that the Wolfsbane potion can be brought to 95%, and left
simmering, until the final ingredient is added, whereupon it must be drunk
while smoking.
