boiled and distilled are two different things.
boiling water to sanitize is simply that. you can use RO, DI, Spring, toilet or any other type of water as the source and boil it.
distilled has gone through the distillation process. boiled off (either with heat or vacuum) and the vapor is condensed and collected. the distillation process leaves almost all of the impurities behind. no impurities may result in the osmotic pressure on the yeast cell walls due to them trying to reach equilibrium.
