Question: I am having a hard time getting the bottles to close?  Any tricks?  Are they defective?
Document: There are great bottles. I got them in a timely manner, really easy to open and close. I will likely buy some more.
I ordered a dozen and one came broken -- not the seller's fault as it was packed well...I think the shipper just tossed it around. 4 Stars for the one broken bottle and the bottles caps are bit tight/hard to use, but you get used to it. Good value for price.
Nothing's perfect but these bottles seem well made and priced right (with shipping I paid just under $3 each.) The "EZ Cap" is a little hard to seal and unseal. The trick to unsealing is to place two hands on top of the bottle with both thumbs just under the mouth and index fingers behind the lower portion of the frame at the hinges and pull back with them.
They are perfect. The only problem was a mistake I made in getting blue instead of amber. I need to see the contents and the blue makes it very difficult.
I needed secure bottling for brewing my water kefir and these are just perfect. They are also fun to open and close. That is, after you connect the cap unit. That part isn't as much fun.
These bottles and caps are really nice however it took half an hour to figure out how to attach the caps so they would close properly. Maybe a diagram or instructions would help!
I purchased these swing-top bottles so I could bottle home brewed hard cider, beer, and mead. I didn't want to save beer bottles and buy a bottle-capper and caps. With these bottles, the stoppers are re-usable (and replaceable if the seal starts to go).All of the bottles arrived from Midwestern Supply intact. You have to install the swing-tops yourself.
The bottles in the picture were not the ones I received. The ones I was shippped were plain. I contacted the company and they offered to give me a partial credit. When I asked how much and if these bottles were even available to purchase I got no response. I still am trying to get the credit and am getting no response back. I would not reccomend this company to do business with.
Beer and cider always taste better out of glass to me - WOW, love this old fashion look and I absolutely love that POP sound when you pop the top of a fresh homemade brew. I will be ordering more soon, as I'm getting addicted to this home brewing thing. Been using plastic bottles, but now I want more glass, the taste is worth the investment!
Good quality bottles. Tops are not hard to put together and it's quite easy once you get the first couple done. Seal is great as well.
Answer: You are correct that it can be almost impossible to get the caps on. First of all, the caps are hard to get on just by their nature. BUT, if the cap is even slightly not perfectly positioned squarely over the bottle mouth, the cap will be VERY hard to get on. I have found that situating the cap slightly more toward the opposite side of the metal latch makes it perfectly seating when it is brought down allowing for a somewhat easy sealing of the bottle.
