Thank you for viewing. This is "Morgan's Brew Bottles" from Morgan's Brewing Company, an Australian homebrewing brand. These are reusable PET bottles for bottling carbonated beverages such as homemade beer. Made of high-quality PET plastic, they are lightweight and less prone to breakage, making them an easy-to-handle and safe alternative to glass bottles. They are designed to prevent beer degradation from UV light and maintain its flavor. They are designed to withstand high pressure from secondary fermentation and are suitable for storing carbonated beverages. Reason for listing: I used these once for making homemade beer, cleaned them, and stored them in a warehouse. They are reusable, which is great, but I still prefer the "pop" of opening a beer bottle with a bottle opener, so I've gone back to using beer bottles, and that's why I'm listing these. I occasionally make homemade beer, let it age, and serve it at BBQs and such. Sometimes it turns out great, sometimes not so much. I think these would be good for those who make a lot of beer and can let it age. Homemade beer is cheap, so I tend to drink too much, and my 20L tank can't keep up with production. I've become a bit lazy with the extra effort, and I often end up buying commercially available beer. I think these are good for those who are willing to put in the effort and enjoy the process. Currently, only one bottle on the left in the third photo has a dent. They show signs of use, but I think they are fine to use after cleaning. Please note that these are used items, so no claims or returns are accepted. Thank you.
