How to Tell if Milk is Off – Try The Sniff Test

sniff test for off milk

Want to know how to tell if milk is off?  Let me share with you the very best method so you’ll never unnecessarily waste a drop again.

I’ve talked before about expiration dates on eggs, and how to check to see if you can eat them past their date.  

But what about milk?  Food waste is a huge problem.  Particularly when it comes to milk.  Here in the UK, a huge one in six pints of milk is thrown away each year.  This is problematic because, in terms of carbon emissions, land use, water use, dairy milk has the biggest impact on the planet.  Wasting less milk where we can is therefore incredibly important. 

Morrisons announced in January 2022 that they are scrapping use by dates on milk. This is great news because this will save millions of pints of milk from being thrown away unnecessarily every year. This is because, when it comes to milk, the use-by date isn’t a great indication of if your milk is usable or not. Instead, bottles of milk sold by Morrisons will still carry “best before” dates. These will give an indication of when the milk will have the best taste, but can often still be used safely for several days after that point.

So, if your milk has reached its expiry date and you’ve still got some left then how do you tell if milk is off? Or if it is still safe to drink?  Do you sniff the carton to see how it smells?  If you do, then what if I tell you then that you’ve been doing it all wrong?

Why The Carton Sniff Test Is Wrong

It’s true.  If you’ve been sniffing the carton/bottle to tell if your milk is off, then chances are unless the milk is definitely off, then you will have been getting a false picture of how the milk actually smells.  

Instead of the milk, you’ll actually have been getting a whiff of the horrible dried-up bits of milk around the rim of the carton.  This may have perhaps caused you to bin the milk unnecessarily early.

My 99-year-old grandad has scant regard for expiration dates on food.  Want to know a true story? Some time ago he found a tin of tomatoes 10 years out of date in the back of his cupboard.  A lesser person might have put the can in the bin.  But no, not my grandad. Nope, he used the tomatoes to make them into tomato soup and ate it regardless.  And you know what?  He was perfectly fine! 

His rule for how to tell if milk is off is simple but dubious.  If he puts milk in his tea or coffee and it curdles then it’s off.  If not, then the milk is fine for consumption, regardless of the date on the carton.

I personally think my grandad’s milk testing method is a bit extreme.  I mean, who wants to potentially waste a perfectly good cup of tea?

So What Is The Best Method To Tell If Milk Is Off?

I disagree with my grandad. In actual fact, the best way to tell if milk is off or not is to pour a little bit of milk into a clean glass.  Then sniff the milk in the glass. If your milk is off, you’ll smell a sour smell indicating that the milk has spoiled.

The glass method gives you a much better idea of if the milk is off or not. This way the dried-up bits of milk around the rim aren’t going to throw you off the scent of fresh milk.

Of course, if in any doubt, do look to see if your milk has curdled. This means you should look for lumps that formed in the milk. If you see any, this is a sign it should not be used.

I find this method fail-safe – you’ll never throw out perfectly good milk again!

Do also remember that milk’s life can be extended by keeping it cool in the fridge. You should also keep milk bottles closed as much as possible.

Top Ethical Soft Drinks To Quench Your Thirst Sustainably

charitea ethical soft drinks

Whether you are taking part in Dry January, are alcohol-free, or are just looking for a tasty way to quench your thirst then try these five ethical soft drinks for size – republished and updated for 2022 from its original 2016 publication date.

Have you ever considered just how ethical your favourite soft drinks are?  I’m not a big soft drinks drinker – give me tea any day, so I have to say I haven’t.  Luckily, Georgina Rawes from Ethical Consumer has put together a post for Moral Fibres readers. 

Here she sheds light on the three issues plaguing the soft drinks industry.  Mainly, sugar, plastic, and workers’ rights – and shares her top five ethical soft drinks alternatives.

An Unquenchable Thirst

We simply can’t get enough of our conveniently packaged, sweet soft drinks.  In 2016, in the UK alone, we spent over £17.4 billion on soft drinks, juices, and bottled water.  Although soft drinks are the seemingly innocent alternative to alcoholic beverages, there is a lot more going on in the bottle than you might realise.

Despite the elaborate advertising campaigns, soft drinks are simple products.  Essentially, they consist of water, sugar or sweeteners, and some fruit extracts. Often there are additives such as flavour enhancers, caffeine, and preservatives.

There are many issues associated with soft drinks.  From sugar production, packaging, and workers’ rights.  We’ll explore these issues in detail. Then we’ll reveal our best ethical soft drink brands, including the Fairtrade and organic drinks.

Floating Islands Of Plastic Waste

No one can have missed recent environmental concern to hit the headlines.  Another island of plastic waste was discovered in 2017 that was the size of Mexico floating in the Pacific Ocean. A recent Greenpeace report states that plastic bottles and bottle tops are the most common plastic packaging washed up on shorelines.  With only 57% of plastic bottles recycled in the UK, you can bet that landfill sites are being overloaded. These bottles are only going to continue to get back into our oceans.

As plastics are churned up and broken down in the ocean they former small pieces.  These are known as microplastics.  Microplastics can enter the food chains causing catastrophic issues.  This ‘invisible’ plastic is also making its way into drinking water.  With no clear policies from major soft drinks companies on how they are planning to tackle the plastic problem, it makes sense to look for ethical softs drinks that offer alternative packaging.

Glass bottle production requires half the minerals and fossil fuels needed to make plastic.  It also requires 17 times less water. And it creates five times fewer greenhouse gas emissions.  Glass can be endlessly recycled. In fact, we’re hitting rates of 68% here in the UK.  Aluminium cans are also a more appealing alternative to plastic.  Recycling an aluminium can only requires 8% of the energy to produce a new one. In comparison, plastic recycling uses 70%.

Sugar – A Sticky Problem

Sugar is quickly becoming public health enemy number one.  It is being blamed for the increase in type 2 diabetes and heart disease.  What’s more, it’s linked to tooth decay and obesity in children.  In fact, soft drinks have been labelled as the single biggest source of added sugar in children’s diets.

In an attempt to reduce our intake of sugary drinks, the government is planning to introduce a sugar tax of up to 24p/litre on drinks that contain over 8g sugar/100 ml.  It sounds like a solid plan.  These public health issues cost the NHS billions each year and it’s clear that sugar is harming our health.  However, Coca-Cola doesn’t agree. As such, they have been working against the sugar tax since its conception. This is as well as lobbying against EU regulations restricting the advertising of sugary foods to children.

Making Soft Drinks Is Thirsty Work

But it’s not just the health issues that should concern us.  It takes between 170 and 310 litres of water to make your average 500ml bottle of fizzy pop.  Alarmingly, only 5% is used in drink manufacturing.  The remaining 95% is used to grow ingredients, the largest of which is sugar.  This goes for sweeteners too. This is because sugar is often used in the production of these additives.

European sugar beet uses less water in production than sugar cane grown further afield, often in water-stressed communities.  It takes companies with robust supply chain management and environmental policies, as we see in ethical soft drinks brands, to reduce their impact on the grower communities.  Sadly, many of the supermarket’s own brands and large brands such as PepsiCo, Nestlé SA, and Coca-Cola have inadequate policies to address and manage these issues.  The brands that control the vast majority of the soft drink market.

Where Does Your Money Go?

If the plastic problem isn’t enough to turn you away from the big brands, then supply chain issues will surely sway you towards more ethical soft drinks. Consistently, we see big brands such as Coca-Cola, PepsiCo, Nestlé SA, and the supermarkets demonstrating a lack of control within their supply chains.

Unfair working conditions in developing countries. A lack of robust environmental reporting. Weak targets to address sustainability issues. These are just some of the issues that result from this.  As these companies increase their profits, we see further injustice, and farmers paid poor wages. We also see water-stressed communities put under more pressure.

For more information, see our company profiles on Coca-Cola, Nestlé, and our supermarket report.

Isn’t it time to support the companies who put ethics before profits?
