UK growers guide to the Best Nettle Tea
I'm Sarah, founder of Wild Cornish Tea in Cornwall, and I've spent the last ten years harvesting, dehydrating, packing and (often) testing nettle tea. Our range of nettle teas has grown to over 30 different varieties and flavours, from pure stinging nettle leaf to herbal tea blends. I'm usually the person who answers your enquiries, so I've heard just about every question there is about nettle tea.
Over that time we've tried almost every nettle tea brand on the UK market. We've also taken a close look at other tea companies across the UK hot beverage scene: what they offer, how they source their products, and how they treat their customers. I'm not telling you this to boast. It's because it means I can say what most suppliers won't.
So here's an honest guide to buying the best nettle tea in the UK. It covers the details that decide whether you receive a dusty old tea bag full of old dried herbs, or a magically fresh cuppa with all the right minerals.
Grab a cuppa; it's a long one, but this could save you from a cup of p****!

Why UK grown nettle tea matters
Stinging nettle (Urtica dioica) is a hungry plant. It pulls up whatever is in the soil, minerals and pollutants alike, so a nettle leaf tea is only as clean as the ground it grew in. Ask any supplier these three questions:
Where exactly were the nettles grown? "Packed in the UK" is not "grown in the UK". Many mass-market nettle tea brands pack here but source their leaf from Eastern Europe or Egypt. If the packet doesn't say, that's usually because the answer isn't flattering.
What was the growing environment? Nettles near busy roads, industrial sites or heavily sprayed fields can carry pesticide and heavy-metal residues. Our Cornish nettle tea is field-grown in a clean meadow above the Atlantic.
How long was the leaf on the road? Leaf that has been shipped, warehoused, shipped again and then packed can be a year old before it reaches your cupboard. Ours is picked, dried and blended in small batches and posted swiftly, so it hasn't sat in a store room. That means no air miles, and the freshest nettle tea we can make.
Fresh vs tired nettle leaf: what to look for
You can judge a nettle tea before you brew it:
Colour. Good dried nettle leaf is a deep, vivid green. Dull, khaki or brownish leaf is old, over-heated in drying or poorly stored.
Leaf size. Look for whole or large pieces of leaf. Fine, powdery "dust and fannings" is the lowest grade, the stuff left over after processing. It stews quickly, tastes flat and can turn bitter.
Stalk. A lot of woody stem means the leaf was bulked out.
Smell. Fresh nettle smells green, grassy and slightly sweet. Dusty, hay-like or musty means it's past its best.
When we cut open the main UK brands' nettle tea bags and compared them side by side, ours was the greenest and the least chopped. That was our own kitchen-table test rather than a lab analysis, but you can repeat it with any tea bag and a pair of scissors.
How nettle leaf is harvested and dried
Harvest timing. Nettles are best picked young and leafy, before they flower and go coarse. Cornwall's mild winters mean many of our plants can be harvested for much of the year.
Drying. Gentle dehydrating locks in the green colour and flavour. Rushed, high-heat drying scorches the leaf and leaves it brown and flat.
Storage. Light, air and damp are the enemies. Look for opaque, resealable packaging, not clear packs on a sunny shelf.
How to brew nettle tea (and test it)
To make nettle tea, put a teaspoon or two of leaf (or one tea bag) in a clear glass cup, add freshly boiled water and leave it covered for 5 to 10 minutes. A good one gives a clear, greenish-gold infusion with a rounded, earthy, slightly sweet flavour. Cloudy, murky or weak and papery means low-grade leaf. We judged each brand's intensity, colour and water clarity this way.
Loose leaf nettle tea or nettle tea bags?
Loose leaf nettle tea lets you see exactly what you're getting, so it's the easiest way to judge quality. Nettle tea bags are convenient, but they're where the dust-grade leaf hides. If you want bags, check that you can see leaf pieces through the paper, or cut one open. Ours are made with whole leaf, but any bag deserves the scissors test.
Flavoured nettle tea blends: read the ingredients
Nettle blends are lovely, and we make over 30 of them, from nettle and lemon balm to nettle and ginger, nettle and peppermint and blood orange nettle tea. All of them are naturally caffeine free herbal teas. A few things to check on any blend:
Is the nettle first on the ingredients list, or just a name on the front?
Is the flavour from real herbs, fruit and spices, or from "natural flavourings"?
Is it certified organic, or does it just use the word "organic" in the marketing?
Is the full list printed on the pack and the website?
Nettle tea benefits: what to expect (and what to be wary of)
People enjoy nettle tea as a natural, caffeine-free herbal infusion, traditionally drunk as part of a healthy routine, and it's popular as a spring tea and a gentle daily brew. Be wary of any supplier promising cures. Nettle can have a diuretic effect, so if you're pregnant, on medication (especially for blood pressure, or blood thinners and diuretics) or have a medical condition, check with your GP or pharmacist first. See our medical disclaimer for more.
How to spot a good nettle tea supplier
Quality shows in how a supplier treats you as well as in the leaf. A good one will:
Tell you where the nettles are grown and when they were harvested.
Answer awkward questions plainly, and not with marketing waffle.
Blend and dispatch in small batches rather than selling year-old stock.
Be happy for you to taste before you commit to a big order.

Nettle tea FAQs
What does nettle tea taste like?
Fresh, good-quality nettle tea tastes earthy, green and slightly sweet, a bit like a mild spinach or green tea without the bitterness. Old, dusty nettle tea tastes flat or hay-like.
Is nettle tea caffeine free?
Yes. Nettle leaf contains no caffeine, so it's a popular caffeine free herbal tea for any time of day.
Where can I buy UK grown nettle tea?
Look for a small producer who states exactly where the nettles are grown and picked. We grow, dry and blend ours in Cornwall and post it across the UK. You can shop our nettle teas here.
How do you make nettle tea?
Use a teaspoon or two of dried nettle leaf (or one tea bag) per cup, pour over freshly boiled water, cover and steep for 5 to 10 minutes, then strain.
Is loose leaf nettle tea better than tea bags?
Loose leaf lets you check the quality of the leaf yourself and generally means whole leaf rather than dust. Good tea bags can work well too, as long as they contain real leaf pieces.
Who should avoid nettle tea?
If you're pregnant or breastfeeding, take medication (particularly for blood pressure, or blood thinners and diuretics) or have a medical condition, ask your GP or pharmacist before drinking nettle tea.
Can I use nettle tea for hay fever or skin concerns?
Many people enjoy nettle tea as part of their routine in hay fever season or for their skin, and we've blended teas with those people in mind. It isn't a medicine, though, so speak to a health professional about any condition. Read more in our posts on nettle tea for hay fever and fig leaf and nettle tea for skin.
