I know people claim that metal spoons change the way caviar tastes, but I'm pretty sceptical. Caviar is stored and sold in metal tins. However, even if using a metal spoon affects the taste of caviar, a mother-of-pearl spoon isn't your only option. A wooden spoon will do, so your second claim is just not true.
