There's only a brief boil in this because it's mead. There are plenty of no-boil meads, like JAOM. Chlorine can be removed just by leaving the water uncovered over night before brewing, but chloramine can't. Chloramine is common. Not treating for it risks chlorophenol creation in the finished product.
