Question: Would this item work with beer or wine bottles?
Document: There is really no explanation...there is nothing wrong with them...they work fine... I am using them as oil pourers in wine bottles.
Bought theses as pour spouts for olive oil and they work fine. Fit perfectly in wine bottles. Aerator could be better but good for the price!
These are perfect for my little project. I make wine bottles into olive oil, veg oil, hand soap and bath soap. The wine bottles work well for this and look pretty too. These Pourers  are perfect for the task.
They don't work with bottles that are larger than about 40 oz. It's a bit of a pain, but that said, it has caused me to buy smaller bottles of more quality liquors. Read into that how you will.The seal is not completely perfect, and it does leak a little bit more than I would have hoped for.
The workmanship on them were flat out poor. The seals are made of stiff plastic. I am disgusted with the quality, expecting metal pourers would be better quality. Within an hour i was in the process of returning them.Warning: Do not buy!My recommendation is to go to the store instead of here. I buy a lot of things off of amazon, but this is one item I would not buy again.
I used several old wine bottles and added these pourers to make a nice simple syrup dispenser for a party I had. They were a hit!
I use for oil and alcohol. Work great. I would recommend this product to a friend without reservation. Great buy.
Great Item !! !
I ordered this exact product item from the same seller a few months ago and since then the photo and description hasn't changed but the product has. Formerly the black seal was more flexible and rubbery and had a larger diameter. My recent purchase ended up being more of a stiffer plastic material and the diameter is actually smaller. I am making olive oil bottles out of ceramics and made them specifically to accomodate the size of the spout i purchsed previously.
They are just ok. They fit maybe 30% of my bottles and they would leak the ones that did fit.
Answer: Yup. I know they work on wine bottles because I've tried it. I believe beer bottles have a similar diameter neck, so they should fit just fine, but I'm not sure how well they work pouring carbonated beverages though.
