There are $n$ large bottles of wine, out of which $n-1$ have been poisoned.
However, consuming a single bottle does no harm, it requires all $n-1$ bottles (or small samples of them) to be consumed by the same person to get poisoned. A person dies of poisoning only at the end of the day. The poison consumed by a person remains in his/her body forever, but does not activate until all the other poisons are also consumed.
You have $100$ people and unlimited time for performing the tests.
What is the largest value of $n$ for which you can identify the good bottle?
