12 best brewers bottle caps

Brewer's bottle caps are essential components in the world of bottling beverages, particularly in the context of beer brewing and homebrewing. These bottle caps are designed to seal bottles tightly, preserving the contents inside and preventing any contamination or oxidation. Here are some key points about brewer's bottle caps:

  1. Material: Brewer's bottle caps are typically made of metal, with the most common material being stainless steel. They can also be made of plastic, but metal caps are preferred for long-term storage of beer and wine.

  2. Closure Types: There are two primary types of bottle caps used in brewing:

    • Crown Caps: These are the classic bottle caps with a circular shape and a crimped edge. They require a bottle capper to seal the bottle. Crown caps come in various colors and may have branding or labeling on the top.

    • Flip-Top Caps: Also known as swing-top caps or Grolsch-style caps, these have a hinged design and a metal clasp that securely seals the bottle. They are reusable and are often found on certain styles of craft beer bottles.

  3. Size: Brewer's bottle caps come in standard sizes to fit common bottle types used in brewing. The most common size is 26mm for crown caps, which fits most beer bottles.

  4. Oxygen Barrier: Some bottle caps are designed with an oxygen-absorbing liner or barrier to reduce the oxygen ingress into the bottle. This is crucial for maintaining the freshness and flavor of the beer or wine over time.

  5. Sanitization: It's crucial to sanitize bottle caps before using them in the bottling process. This helps prevent contamination and ensures the quality of the final product.

  6. Sealing Process: To seal a bottle with a crown cap, a bottle capper is used.The capper crimps the edges of the cap tightly around the bottle's lip, creating an airtight seal. For flip-top caps, you simply press down on the cap's clasp to secure it in place.

  7. Bottle Conditioning: Brewer's bottle caps play a critical role in bottle conditioning, a process often used in homebrewing and craft beer production. During bottle conditioning, yeast and sugar are added to the bottle before sealing it with a cap. This allows carbonation to naturally develop inside the bottle.

  8. Customization: Some brewers choose to use custom-printed bottle caps to brand their homemade beverages or add a personalized touch to their products.

In summary, brewer's bottle caps are vital components in the bottling and preservation of beer, wine, and other homemade beverages. They come in different types, sizes, and materials, and their proper use is essential for maintaining the quality and freshness of the final product.

User questions & answers

Question: Trying to make a recirculating draft line cleaner, and I need adapt this to fit a standard garden hose thread. What is the thread pattern of this
Answer: This will not work on a garden hose. It's threaded to match a 2 litre soda bottle. I would recommend a short silicon hose with a garden house threaded Barb on one side and a quick disconnect on the other.
Question: Is this hard to screw on and off? I have a plastic one and it is hex shape. Seems like this would be difficult to get off since it is round
Answer: It hand tightens on and hand-unscrews back off. The only difficulty you'll have is that when you put it on your hand it dry, but if it gets wet through a spill on the side of the bottle or condensation you'll have a hard time getting as good a grip as you had when you put it on. Just don't tighten it that much, you'll be fine.
Question: Does this fit gas (grey) and liquid (black) ball lock connectors, or just gas
Answer: As far as I know just gas ( gray ) but it works great .. I make my own soda ( sugar free)
Question: was debating purchasing this for my PET bottle's i got with my mr.Beer kit, worth the money
Answer: The caps work great. Good seal. I have three that I use in rotation on bottles from store bought seltzer water. I'm carbonating water with pressure set at 45 PSI.

User questions & answers

Question: Why do I need different gaskets? What's the difference
Answer: I'm not completely certain but aside from being extras they are also intended for a different air tight seal. I believe the ones that come attached to the lid, seal more tightly and are intended for longer fermentations while the gaskets in the bag that come with the hole in the center, are intended for your standard medium length fermentations.
Question: Can you put these bottles and the gaskets in an autoclave
Answer: Another way to sterilize is to place them on the lowest rack of a cold oven, set the oven for 180 degrees Fahrenheit and turn it on. When the oven reaches temperature set a timer for 20 minutes. Turn the oven off when the timers goes off and allow the bottles to cool. You don’t have to remove the silicone gasket but you can if you want. Just make sure it is washed properly before you use it. Fill the bottles as soon as possible.
Question: can you use these bottles for fermentation
Answer: Yes, I use them to second ferment my kombucha.
Question: Are these bottle made in the USA
Answer: These bottles are made in China, do hope can solve your question.

Product description

144 Silver Beer Caps

  • Easy to Use
  • Helps reduce oxidation and premature staling
  • Perfect for beers that you plan to age

User questions & answers

Question: Is the shipping free like it says on this page
Answer: Yes if the listing is labeled as free shipping it is. If you are using Amazon Prime, HomeBrewStuff products are not eligible.
Question: Is there a point to using these as opposed to standard caps if they are going to be sanitized by liquid sanitizer
Answer: I have used 02 caps for a long time. I usually make ale or stout with high alcohol content (9% or more), and I always sanitize the caps. With the removal of oxygen in the airspace between beer and cap, I have been able to store my brew for 3 years or more. No such luck with standard caps.
Question: Does anybody know the measurements, in inches or millimeters, across the flat top of these caps
Answer: If there is such a thing as a "standard" bottle cap this is it. I measured it with a ruler and would say it is 1 inch across the top.
Question: I need caps for 12 oz bottles. Will all caps fit on all sizes of beer bottles
Answer: They will work for 12 oz bottles as long as they are not screw-off caps. You have to have bottles that you need an opener for.

Product description

24 - 12oz Amber Beer Bottles

User questions & answers

Question: Are these able to be cleaned/ re-sanitized and used multiple times
Answer: Yes, After use I rinse and spray with Star San, let dry until reuse. Sanitize once more with Star San just before refilling. This can be done many times.
Question: Are the bottles glass or plastic
Answer: The bottles are glass
Question: What Colors are available? Can you do a custom color
Answer: Unless you're looking for a dark color, I'd nix the color idea. Beer needs dark bottles to store in, otherwise it will spoil faster.
Question: Are these empty bottles a better deal than the reuseable ones at Costco filled with a variety of fairly decent beers for $18 to $22 per case
Answer: These bottles are standard reusable ones and should be the same as Costco's. They need a new set of caps per each use and will hold the pressure of carbonation. I think they are a good deal if you brew your own. Out of five cases I have never lost one. Costco's should be the same to reuse.
