Have seen black plastic 40 l kegs. They were used for Canadian Club so i have been told as a one off keg. Does anyone have any info or feedback on them. 1 is set up as a fermenter and second one is stock and the price was $60. Did not look like it had a CUB type ball lock on it. Maybe someone out there has come across them and knows what fitting they have. Seller said they were good for wine storage in stock form, as it can be dismantled for cleaning and are very good as fermenters. Has anybody ever used them for beer storage or fermenting.
