If you enjoy mixing drinks, bottling homebrew, or just keeping your pantry stocked with resealable bottles, the small detail of choosing the right bottle cap makes a big difference. Think of caps as the unsung heroes of your home bar — they keep carbonation alive, stop spills, and can even dress up a bottle like a bow on a gift. Whether you prefer crown caps, swing-top closures, or cork stoppers, the right choice affects flavor, shelf life, and presentation.
Not all caps are created equal. You’ll meet a handful of common types in UK shops and online marketplaces: crown caps for beer, screw caps for sodas and sauces, swing-top ceramic closures for artisan brews, and corks or tapered stoppers for wine. Each has pros and cons depending on what you’re bottling and how you plan to store it.
Crown caps are the classic metal caps you pop off with a bottle opener. They’re cheap in bulk and ideal for bottling beer and carbonated soda. If you bottle in 12 fl oz or 16 fl oz sizes, crown caps are the standard — just remember you’ll need a capper to crimp them tight.
Screw caps offer convenience for everyday pantry bottles and mixers. They work great for sauces, oil, or non-carbonated beverages. Plastic seals are lightweight and reusable, which is handy if you re-bottle frequently.
Swing-top closures are both functional and stylish. They’re perfect for 16 fl oz or 25 fl oz artisan bottles and are reusable for many cycles. The rubber gasket creates a tight seal, making them ideal for keeping carbonation in craft sodas and homebrewed ales.
Corks remain a top choice for wines and certain spirits. For those who want a modern alternative, silicone or tapered rubber stoppers provide excellent reusability and are easier to insert and remove than natural corks.
Shopping for caps and bar accessories is easy if you know where to look. Major online marketplaces, department stores, specialist kitchen retailers, and homebrewing suppliers all stock closures and tools. Below are reliable places to search, each offering different strengths in price, selection, and convenience.
Amazon UK and eBay UK offer enormous selections and fast shipping for many sellers. If you need bulk crown caps, replacement gaskets, or a range of swing-top bottles in different sizes, marketplaces are a convenient one-stop shop. Compare reviews and seller ratings to avoid low-quality items.
Stores like John Lewis, Lakeland, Dunelm, and Robert Dyas often stock stylish barware, wine stoppers, and accessories. These chains are great when you want to see items in person or prefer the security of buying from a well-known retailer. Expect higher finish quality and better customer service for premium barware picks.
If you’re bottling beer, cider, or kombucha, specialist homebrew shops are your best bet. These suppliers stock capper tools, crown caps in bulk, sanitizers, and bottles sized for 12 fl oz and 16 fl oz fills. Specialist retailers also sell advice — a huge plus if you’re new to bottling.
Here’s a practical list of trusted shops that sell bottle caps and barware in the UK. I mention familiar national names and specialist categories so you can pick the best source for price, variety, or expertise.
Amazon gives unmatched range and user reviews. You’ll find crown caps, swing-top bottles, corks, capper tools, and bulk packs of 100 or more caps. Prime shipping can be handy if you suddenly run out mid-project.
eBay is great for sourcing oddball sizes, vintage caps, or bulk lots at competitive prices. Auction listings can score you a bargain, but check seller feedback and item pictures carefully.
John Lewis offers durable, stylish barware and wine accessories. Their range suits people who want attractive presentation items such as decanters, premium stoppers, and cocktail sets that pair well with quality closures.
Lakeland is a kitchen and home specialist with practical bar tools and cleaning equipment. You’re likely to find bottle brushes, funnels, and reusable silicone stoppers alongside caps and openers.
These high-street retailers stock budget-friendly barware and cookware accessories. They’re good for everyday bottle caps, resealable lids, and quick household solutions without the specialist markup.
Wine retailers like Majestic offer corks, wine stoppers, and presentation items tailored to wine bottles. They’re useful when you want closures that complement wine styles and bottle neck sizes, especially for gift or cellar bottles.
Specialist homebrew stores — both brick-and-mortar and online — supply crown caps, professional capper tools, sanitizers, and bottles specifically designed for carbonated beverages. They’re invaluable for serious brewers who bottle in larger quantities and need consistent quality.
Choosing a cap means balancing practicality, cost, and aesthetics. Start by asking what you’re bottling, whether it’s carbonated, and how long it needs to last. From there, match the closure to the bottle mouth type and think about reusability. For example, crown caps are perfect for single-use carbonated bottles, while swing-tops are ideal when you want to keep reusing the same bottle.
Always check the bottle mouth diameter and thread type before buying caps. A common practice is to measure the inner diameter in inches. If you plan to reuse bottles, measure both bottle opening and overall height; a mismatch can lead to leaky seals or wasted money.
Carbonated drinks exert pressure inside the bottle, so pick caps and gaskets designed to withstand that pressure. Crown caps and quality swing-top closures are built for carbonation, while some screw caps and cheap plastic lids aren’t as reliable for fizzy beverages.
Buying caps is only part of the story. The right tools make bottling safe and efficient. Here are essentials to keep on hand.
A good hand capper crimps crown caps onto bottles fast and evenly. There are lever-style cappers and bench cappers; choose based on batch size. Lever cappers are affordable and fine for home brewers bottling in 12 fl oz or 16 fl oz bottles.
Sanitation prevents spoilage. Pick up bottle brushes, no-rinse sanitizers, and a designated bottling bucket. A clean bottle equals a happy fermentation and a better-tasting drink.
Labels, shrink sleeves, and storage racks help you identify batches and keep bottles safe. If you’re gifting or selling, presentation elements from department stores or online marketplaces can be the finishing touch.
Bulk buying reduces price per cap and is smart if you bottle regularly. Expect bulk crown cap packs priced much lower per unit than single packs. On the other hand, buying single or small packs works if you just need a few replacement stoppers or want to test a new closure type before committing to a case.
If you bottle dozens of 12 fl oz beers or make batches of sodas weekly, bulk crown caps and multi-packs of swing-top bottles save money and trips to the store. Homebrew suppliers and marketplaces like Amazon usually offer the best bulk deals.
Singles make sense for decorative stoppers, specialty corks, or premium glass swing-tops you only need a couple of. Department stores and wine shops stock high-end options sold individually.
Concerned about waste? You can make greener choices. Reusable swing-top bottles, silicone stoppers, and stainless-steel caps cut single-use waste. Some suppliers also sell recyclable metal crown caps and biodegradable packaging.
Using reusable closures and returning to refill shops can drastically reduce waste. If you like the idea of a refillable kitchen, look for swing-top bottles and high-quality stoppers that last for many cycles.
Prices vary widely: a pack of 100 crown caps can be a budget-friendly purchase, while a premium swing-top bottle costs more per item but lasts for years. Compare unit price, material quality, and shipping costs. Sometimes paying a bit more upfront saves money in the long run because quality closures prevent leaks and spoilage.
Remember tools and sanitation supplies when budgeting. A cheap cap without a proper capper or sanitizer can lead to ruined batches. Factor in the cost of a good hand capper and no-rinse sanitizer when planning your project.
Before clicking buy, run through this quick checklist: Is the cap type appropriate for your beverage? Does it fit your bottle mouth in inches? Are you buying in a sensible quantity? Do you have the right tools to apply the cap? Will the closure hold carbonation if needed? This simple verification avoids costly mistakes down the line.
Keep a sample bottle and a ruler on hand when ordering online. Measure the opening in inches and compare to seller specs. It’s a small step that prevents returns and mismatch headaches.
Finding the right bottle caps and barware in the UK is a mix of knowing what you need and choosing the right store. From online marketplaces like Amazon and eBay to department stores such as John Lewis, Lakeland, Dunelm, and specialist homebrew suppliers, you’ve got options for every budget and level of expertise. Prioritize fit, durability, and the demands of carbonation, and don’t forget the tools and sanitizers that make bottling a breeze. With the right caps and a few helpful accessories, you can keep your drinks fresh, presentable, and perfectly sealed for whenever you want to pour.
