Why Glass Spice Jars Are a Great Choice

The key to delicious recipes is to use fresh, authentic spices that have been well-cared for and kept away from light, heat and moisture. This means thinking carefully about how you store them. If you store spices in plastic tubs, they can take on the odour of the plastic and there is also a risk that plastic chemicals will leach into the contents. If you store spices in their original cardboard packets, they tend to degrade quickly.

One of the best and most enduring ways to store spices and herbs of all kinds is to choose glass spice jars. At Wares of Knutsford, we stock a wide range of beautiful glass jars that are suitable for storing herbs and spices, and they look stunning lined up in your pantry to inspire your next cooking project.

Let's look at some of the benefits of storing spices in glass jars

Why Store Spices in Glass Jars?

Spices have been prized as a cooking ingredient for millennia for their incredible ability to add flavour, depth, aroma and powerful health benefits to dishes. However, they are naturally fragile plant-based foods that need to be carefully preserved, or these precious ingredients can easily become damaged.

Spices are often dried before being stored, and they last for the longest if they are kept in clean, dry, dark storage jars where there are no competing flavours or aromas (unless you are storing spice blends), and where the spices can be labelled for easy identification, dated and then used quickly.

Glass is the perfect storage solution because it is natural and chemical-free. Glass also has no odour that can permeate the spices, in contrast to plastic storage boxes, which can create a lingering distinctive smell that damages the fragile aroma.

Glass jars also have the benefit of being durable and yet genuinely inexpensive. They can last for years with the right care and can be easily cleaned between use. What's more, glass jars look beautiful, and they can be easily customised with labels or pretty lids to create a spice rack that's worthy of display

How to Find the Best Glass Spice Jars

The best glass spice jars tend to be small - around the 50ml - 150ml size - and have clip-top, glass stopper or screw-top lids. This keeps the jars airtight and prevents the contents from quickly degrading. We have a great range of glass jars that are suitable for herb and spice storage, and we regularly update our lines, too, so you'll easily find the perfect storage solution for your kitchen.

You'll note too that we sell spice jars with grinder tops which are great for storing ingredients such as dried peppercorns, ready to grind straight onto your cooking. Again, this maximises the flavour and aroma so that the fragile volatile oils and compounds in the spice itself are stored carefully until they are released in the grinding process.

Excellent Value at Wares of Knutsford

We stock glass jars suitable for spice storage in a wide range of volumes, including pallet-size orders. This means you can save increasing amounts on the unit cost as you build up your order. Many of our customers also order these smaller style glass jars for a variety of home, wedding, event or small business projects as they are highly versatile and can be used in many ways. We offer competitive rates on fast delivery, too, so you can always be stocked up at short notice if you are preparing for a special occasion or stocking a business.

Ideas for Using Spice Blends

Spice Blends are a great way to have ready-mixed, themed flavour mixes that can be instantly added to recipes to create a delicious flavour and fragrance. You can pre-combine spice blends in a bowl and decant them into your glass jars, or even add them to the glass spice jars directly and give them a shake.

Cajun Seasoning Recipe

Cajun seasoning is a wonderful spice blend that goes with nearly all dishes, with its bold and zesty flavours that combine perfectly with seafood, chicken, veggies and more. Simply find your measuring spoons and take equal amounts of:

Smoked paprika

Onion Powder

Cayenne Pepper

Dried Oregano



Garlic Powder


And combine everything well before storing it. If you label these jars, they also make lovely wedding favours or gifts for keen cooks. Add a pretty label and ribbon, and they'll look fantastic!
