What You'll Learn
Plastic carboys are safe to use with the proper care
Plastic carboys are safe to use for wine with the proper care. Firstly, it is important to know what type of plastic you are dealing with and what was in the container before. Any plastic that comes into contact with wine for any length of time should be food-grade plastic.
There are several advantages to using plastic carboys. They are significantly lighter than glass carboys, making them easier to handle and reducing the risk of accidents. They are also less expensive and less breakable than glass. However, plastic carboys have a softer surface and are more porous, making them more susceptible to contamination. Scratches on the inside of plastic carboys can harbour substances that can ruin the wine and provide hiding places for spoilage microorganisms. Therefore, it is crucial to take extreme care when cleaning plastic carboys and avoid using brushes that can scratch the surface. Some winemakers recommend replacing plastic carboys after about 5 to 7 uses, regardless of whether they are damaged.
Another concern with plastic carboys is the potential for chemicals to leach into the wine. Bisphenol-A (BPA), a chemical found in some plastics, has been linked to adverse health effects, including cancer. However, PET fermentation carboys are specifically designed to address this issue. They do not release flavours into the wine, have low oxygen permeability, and are easier to wash than glass.
Overall, plastic carboys can be safely used for wine with proper care and attention to the type of plastic, cleaning, and replacement.

Plastic carboys are cheaper, lighter, and less breakable
Plastic carboys are a great option for wine storage if you are on a budget. They are significantly cheaper than glass carboys, which can be up to 50% more expensive. This cost difference is important to consider, especially if you are just starting out in winemaking and want to keep costs low.
Another advantage of plastic carboys is their weight. A standard 6-gallon plastic carboy weighs around 5 lbs, almost four times lighter than a glass carboy, which typically weighs 19 lbs when empty. This weight difference makes plastic carboys much easier to handle and manoeuvre, especially when full. A glass carboy filled with wine can weigh up to 60 lbs, making it challenging to lift and move without assistance.
Plastic carboys are also less breakable than their glass counterparts. Glass carboys are brittle and prone to shattering when dropped, which can result in a mess of wine and broken glass. Plastic carboys, on the other hand, are more flexible and durable. If you accidentally bump or drop a plastic carboy, it is less likely to break, reducing the risk of injury and wine wastage.
While plastic carboys offer these benefits, it is important to consider their limitations. Plastic carboys can be more challenging to clean and are more susceptible to scratching. These scratches can harbour microorganisms and contaminants that can affect the quality of your wine. Additionally, some winemakers have expressed concerns about the potential for plastic carboys to leach chemicals, such as Bisphenol A (BPA), into the wine.
Overall, plastic carboys are a cost-effective, lightweight, and durable option for wine storage. However, it is essential to weigh these advantages against the potential drawbacks related to cleanliness and chemical safety. Regular cleaning and sanitising, as well as the use of food-grade plastics, can help mitigate these concerns.

Plastic carboys may leech chemicals into wine
Plastic carboys are a popular choice for wine storage due to their lightweight, durability, and cost-effectiveness. However, one significant concern with using plastic carboys is the possibility of chemical leeching.
Plastic carboys, particularly those made from polyvinylidene chloride (PVCD), have been known to leech chemicals into the wine. Bisphenol-A (BPA) is one of the most harmful chemicals that can leech into wine from plastic carboys. BPA is a known endocrine blocker and carcinogen, and it can adversely affect the development of the fetus in pregnant women. As a result, it is crucial to ensure that any plastic coming into contact with wine for an extended period is food-grade plastic.
While PET fermentation carboys are marketed as a safer alternative to traditional plastic carboys, some winemakers still prefer glass carboys to eliminate any risk of chemical leeching. Glass carboys are heavier and more fragile, but they can be scrubbed clean without scratching and do not pose the same chemical concerns as plastic. However, glass carboys can be more expensive, and there is a risk of breakage, which can be dangerous and result in wine loss.
To mitigate the risk of chemical leeching in plastic carboys, some winemakers recommend replacing them after 5 to 7 uses, regardless of whether they are damaged. Additionally, it is essential to properly clean and sanitize plastic carboys, especially when purchasing them second-hand, as scratches and previous use may increase the likelihood of chemical leeching.
In conclusion, while plastic carboys are convenient and affordable, the possibility of chemical leeching into the wine is a valid concern. Winemakers must carefully consider the advantages and disadvantages of plastic and glass carboys and take the necessary precautions to ensure the safety and quality of their wine.
