Quick answer: To turn a wide-mouth Ball mason jar into an iced-coffee cup, add a correctly sized drinking lid and reusable straw, keep the jar upright, and avoid sudden temperature changes. The most important step is checking that the jar is truly a standard wide-mouth jar before buying the lid.

How to Turn a Ball Mason Jar into an Iced Coffee Cup
There is something satisfying about using the jar that is already in the cabinet. It is sturdy, familiar, easy to see through, and probably has a better story than a cup bought on impulse.
A drinking lid gives that jar a different job. Instead of storing oats or sitting beside the canning supplies, it can hold the iced coffee you make before work.
Morning scene: the 3.5-inch ANOTION lid sits on a standard wide-mouth jar, with a stainless steel straw passing directly through its 12 mm bamboo opening.
What you need
- A clean standard wide-mouth Ball or Kerr-style mason jar
- A wide-mouth drinking lid with a straw opening
- A reusable straw that fits the opening
- Ice and a fully cooled drink
The ANOTION bamboo replacement-lid set includes two lids, two stainless steel straws, and a brush. Mason jars are not included.
Step 1: Check the jar opening
Measure across the outside edge of the threaded opening. A standard wide-mouth closure is roughly 3.5 inches across. Do not rely on the jar capacity alone; 16 oz and 32 oz jars can share the same mouth size.
If you are using a repurposed pasta, salsa, or pickle jar, assume nothing. Commercial jars often use a different thread. Our regular-mouth vs wide-mouth guide explains how to measure without guessing.
Step 2: Start with a cool jar and cool coffee
Glass does not enjoy a sudden temperature shock. Do not pour very hot coffee into a cold jar filled with ice. Brew the coffee, let it cool, then add it to the jar with ice. Cold brew is even simpler because it starts cold.
Step 3: Add the lid without overtightening
Seat the drinking lid evenly and turn it until it feels secure. It should not wobble or sit at an angle. Do not force a lid onto threads that do not match. A stubborn fit is usually a size problem, not a cue to twist harder.
Step 4: Treat it like a cup, not a sealed bottle
A straw opening means the lid is not fully sealed. Keep the jar upright on a desk, counter, picnic table, or car cup holder that supports its shape. Do not toss it into a tote beside a laptop and hope for the best.
Step 5: Wash the pieces separately
Rinse the straw soon after milk, sweet cold foam, matcha, or smoothies. Use a narrow brush to clean the inside. Hand wash a bamboo lid with mild soap, rinse it, and dry it right away. Let it finish drying in open air before storing it.
Do not soak bamboo or run it through the dishwasher. The dishwasher is convenient for many glass jars, but the lid needs gentler care.
Three iced-coffee combinations that work well in glass
Brown sugar oat milk coffee
Add a small spoonful of brown sugar syrup, cooled coffee, oat milk, and plenty of ice. Stir before adding the lid so syrup does not settle under the straw.
Simple vanilla cold brew
Fill the jar halfway with ice, add cold brew, then a splash of milk and vanilla syrup. Glass shows the layers, which is half the pleasure.
Iced matcha with strawberry
Muddle a few strawberry pieces, add ice and milk, then pour whisked matcha over the top. Use a straw brush immediately afterward because fruit pulp likes to stay behind.
When a complete glass tumbler makes more sense
A replacement lid is a good choice when you already own standard jars and mostly drink at home or at a desk. A purpose-built tumbler makes more sense when you want a handle, a narrower base for a car cup holder, a larger 40 oz capacity, or a lid designed for a specific travel routine.

Frequently asked questions
Can I put hot coffee in a mason jar?
Use the temperature guidance provided by the jar manufacturer and avoid sudden temperature changes. For an iced drink, cool the coffee before adding it to a cold jar with ice.
Can I put a bamboo drinking lid in the dishwasher?
No. Hand wash it and dry it promptly. The glass jar may have different care instructions.
Can I carry the jar in a bag?
Not with an open straw lid. Keep it upright and use it as a drinking cup rather than a sealed bottle.
