Better-Bottles are plastic carboys made from PET plastic as an alternative to glass. They are guaranteed to be 100% safe to use for your wine making without imparting any off flavors or aromas. In addition, they weigh about 1 pound, instead of the 12-15 for traditional glass carboys. So far, everyone that has used them has had nothing but praise for them.
By the way, since they are plastic, they do not shatter when you drop one!
