If you want tea without caffeine, choose a herbal infusion, also called a tisane. Peppermint, chamomile, ginger, rooibos and fruit blends contain no caffeine because they don’t come from the tea plant. Decaffeinated black or green tea is a different thing: the caffeine has been removed, but a trace is left. This guide explains the difference, how to choose by situation, where mushroom tea fits, and when to check with a professional first.
TL;DR
- Only infusions that never touch the tea plant (Camellia sinensis) are naturally caffeine-free. Decaf tea is low in caffeine, not zero.
- Peppermint, chamomile, ginger, rooibos, honeybush, hibiscus and fruit infusions are the usual caffeine-free choices. Mushroom blends can join them if the base contains no tea leaf.
- Pregnant? NHS guidance is to keep caffeine to 200mg a day or less, and caffeine-free infusions are a simple way to stay under it. If you are on medication, ask your pharmacist or GP before adding a new herbal habit.
- Choose by what you want from the cup: comfort, flavour, a wind-down ritual or a coffee swap.

Why “decaf” and “caffeine-free” are not the same
The words sit side by side on supermarket shelves, so it is easy to treat them as synonyms. They aren’t.
Naturally caffeine-free drinks come from plants that never contained caffeine in the first place. Herbal and fruit infusions fall here. Nothing has been taken out, because nothing was there.
Decaffeinated tea starts as black, green, white or oolong leaf from the tea plant, which naturally contains caffeine. The caffeine is extracted after harvest. The process removes most of it, but a small residue usually remains. If you are avoiding caffeine entirely, for example because it keeps you awake or because you are pregnant and counting every milligram, a naturally caffeine-free infusion is the cleaner choice. If you simply want your builder’s-style cuppa to be gentler, decaf does the job.
One trap to watch for: a blend that is “herbal” on the front of the box but includes some green or black tea in the ingredients list. Read the ingredients, not just the name. Matcha, yerba mate and guayusa also contain caffeine, even though they are sometimes sold alongside herbal drinks.
How much caffeine are you avoiding?
For scale, the NHS estimate quoted in pregnancy guidance is about 100mg of caffeine in a mug of instant coffee and 75mg in a mug of tea. The British Heart Foundation puts the averages a little differently, at around 100mg for a cup of coffee and around 50mg for a cup of tea, and notes that it varies. Strength, leaf quantity, brewing time and mug size all move the number.
So a few cups of ordinary tea over a day adds up faster than most people think, which is why a caffeine-free option for the afternoon and evening makes sense even if you are happy with caffeine at breakfast.
The main types of caffeine-free tea
Here is a practical rundown of what you will find in a British supermarket or online, and what each is good for.
| Type | Flavour | Best for |
|---|---|---|
| Peppermint | Cool, clean, slightly sharp | After meals, a fresh palate |
| Chamomile | Soft, floral, apple-like | Evenings, winding down |
| Ginger (with or without lemon) | Warming, spicy | Cold days, a cosy mug |
| Rooibos (redbush) | Round, malty, mildly sweet | Replacing builder’s tea, takes milk well |
| Honeybush | Honeyed, gentle | A sweeter cup without sugar |
| Hibiscus and fruit infusions | Tart, fruity | Iced drinks, a bright afternoon pick |
| Fennel, lemongrass, spearmint | Light, aromatic | Mild, easy sipping |
| Mushroom botanical blends | Smooth, earthy, balanced by botanicals | A daily ritual, a coffee or tea swap |
Rooibos and honeybush: the closest to “normal” tea
If what you miss is a dark, full-bodied brew you can add milk to, rooibos is the usual answer. It is grown in South Africa and is not related to the tea plant. Honeybush, from the same region, is softer and sweeter. Both are commonly described as low in tannin, which is why people who find black tea harsh or astringent often get on with them. Tannins are the compounds behind that dry, puckering feeling in the mouth.
Mint, chamomile and ginger: the classics
These are the cupboard staples for good reason. They are cheap, easy to find, and each has a clear job: mint after dinner, chamomile before bed, ginger when you want warmth. Their strength is simplicity. If you want to know exactly what is in your mug, a single-ingredient infusion is the most transparent option.
Fruit infusions: fun but check the label
Fruit blends are naturally caffeine-free, but they vary a lot in how much real fruit they contain. Some are mostly flavouring. Hibiscus-based blends give a tart, ruby brew that works hot or cold.
Low tannin: what it means and who cares
People searching for low-tannin or tannin-free tea are usually after one of two things: a smoother taste, or a drink that is less drying and bitter. Herbal infusions tend to be gentler than strongly brewed black tea on both counts, though the picture differs between ingredients and the amounts depend on how you brew. Over-steeping makes almost any tea more bitter.
If tannin is your concern, two practical tips help. First, shorten the steep and use water just off the boil rather than rolling boiling for delicate herbs. Second, try a blend built around rooibos, honeybush or mushroom, which taste rounder than leaf teas. We don’t publish tannin measurements for our own blends, so we won’t make a number-based claim about them here. What we can say is that we blend with smoothness in mind, which we cover below.
Choosing by situation
For the evening and sleep
Chamomile, rooibos and a Reishi blend are the common wind-down choices. No tea can promise you a night of sleep, and sleep problems that persist deserve a conversation with your GP. But swapping a late caffeinated cup for something caffeine-free removes one obvious thing that can get in the way, and a warm, slow drink can be a useful cue that the day is ending.
For pregnancy and breastfeeding
This is where caution matters most. NHS guidance in a pregnancy leaflet says you don’t need to cut caffeine out completely but should keep it to no more than 200mg a day from all sources, and suggests trying decaffeinated tea and coffee or fruit juice. An NHS England infographic on caffeine in pregnancy lists herbal teas among the alternatives to caffeinated drinks.
Here is the catch: “caffeine-free” does not mean “safe in any quantity”. Some herbs have little safety data in pregnancy, and the same is true while breastfeeding. NHS Healthier Together guidance on breastfeeding explains that traces of what you eat and drink pass into breast milk and points you to a professional if you have concerns. Before you start any herbal or mushroom product while pregnant or breastfeeding, check the ingredients with your midwife, pharmacist or GP.
For people on medication
“Natural” is not the same as “interaction-free”. A review of natural products and tamoxifen found potential interactions in pre-clinical studies, while noting that the clinical evidence is still thin. If you take prescription medicines, particularly hormone therapies, ask your pharmacist or GP before adding a new herbal habit. This applies to mushroom blends as much as to any other botanical.
For a coffee swap
If you are cutting back on coffee, the loss is often not just caffeine but the ritual: something hot, a slightly bitter or earthy depth, a defined pause. Peppermint won’t replace that. Rooibos, roasted-tasting infusions and mushroom blends come closer, because they have more body.
Where mushroom tea fits
This is the part of the category that is newer to most British readers, and it prompts a very common question: does mushroom tea have caffeine?
It depends on the product. Mushrooms themselves do not contain caffeine, so a drink made from mushrooms and botanicals with no tea leaf or coffee in it is caffeine-free. But if a brand blends mushroom with black tea, green tea or coffee, the caffeine from those ingredients is still there. The same applies to “mushroom coffee”, which by definition contains coffee. Check the ingredients list every time.
Our own blends are naturally caffeine-free. They combine fruiting body mushrooms with aromatic botanicals, and there is no tea leaf or coffee in the cup.
Fruiting body, not just “mushroom powder”
The label detail that matters most on any functional mushroom product is what part of the mushroom has been used. Many products use mycelium grown on grain, which can leave a lot of starch in the powder. Fruiting body is the mushroom itself, the part you would recognise. We make our blends with fruiting body mushrooms, at 40% of each blend, with botanicals making up the rest for flavour and balance.
If you want to read more about the basics, our beginner’s guide to functional mushrooms and botanical tea goes through each species.
What the evidence does and doesn’t say
We want to be straight with you. Traditional use of mushrooms such as reishi is long, and teas and tonics are among the traditional preparations. A monograph on Ganoderma lucidum (reishi) records that history alongside modern forms such as extracts and capsules. But traditional use is not the same as proof. The National Cancer Institute’s PDQ summary on medicinal mushrooms notes that regulators have not approved medicinal mushrooms as a treatment for cancer or any other medical condition. Mushroom tea is a drink for daily wellbeing, not a treatment, and it should not replace medical advice or medicines.
Our perspective on caffeine-free tea
We started MycoBrew because we wanted a caffeine-free cup that felt like a proper ritual rather than a compromise. Most caffeine-free options are pleasant but one-note: you drink peppermint because you can’t have the other thing. We wanted a mug that you reach for because you like it.
That is why we focus on three things. First, the mushroom content: 40% fruiting body in each blend, rather than a token pinch. Second, taste: mushroom can be earthy and, in poorly made products, gritty or bitter, so we balance each blend with botanicals to give a smooth cup without a dominant mushroom flavour. Third, quality: our blends are organic, crafted in the UK, lab-tested, and packed in biodegradable pyramid tea bags.
Our honest advice is this. If you simply need zero caffeine, any plain herbal infusion will do it, and there is no shame in a good peppermint tea. If you want a daily ritual with more depth, with each blend built around a specific mushroom (Lion’s Mane, Reishi, Shiitake, Maitake or Agaricus), that is where we come in. And whichever you choose, treat it as part of a varied routine, not a cure for anything.

How to brew a good caffeine-free cup
A few habits make any caffeine-free tea taste better.
- Use fresh water. Re-boiled water tastes flat.
- Warm the mug. A rinse of hot water keeps the brew hotter for longer.
- Give it time. Herbal infusions and mushroom blends generally need longer than black tea. Follow the steeping time on the pack, and cover the mug to hold in aromatic oils.
- Don’t over-steep. Past the recommended time, bitterness and astringency creep in.
- Taste before you add anything. Many caffeine-free teas, rooibos and honeybush especially, are naturally sweet enough without sugar. That also helps with the NHS advice on cutting back on sugar in hot drinks, which appears in guidance such as this NHS leaflet for new mums.
That same leaflet reminds readers that water, lower-fat milk and sugar-free drinks, including tea and coffee, all count towards 6 to 8 drinks a day. Caffeine-free infusions are an easy way to add variety to that total.
What to look for on a label
Whether you buy from us or elsewhere, a short checklist saves disappointment.
- Ingredients list: is there any Camellia sinensis, green tea, black tea, matcha, mate or coffee? If so, it is not caffeine-free.
- Claims: be cautious about anything that promises to cure, treat or balance a medical condition. Experts note that herbal safety is not guaranteed just because a product is natural.
- Mushroom form: fruiting body, mycelium on grain, or an unspecified “mushroom powder”? Percentages are a good sign, because they show the maker is willing to be specific.
- Testing: third-party or lab testing matters more with herbal products because oversight is more limited than for medicines.
- Packaging: if you care about the environment, check what the bag is made of. Not all tea bags are plastic-free.
FAQ
Is there any tea that is completely caffeine-free?
Yes, any herbal or fruit infusion made without leaves from the tea plant, such as peppermint, chamomile, ginger, rooibos or honeybush. Decaffeinated black and green teas are low in caffeine but are not completely free of it. Always check the ingredients, as some blends add tea leaf.
Does mushroom tea have caffeine?
Mushrooms do not contain caffeine, so a mushroom tea made only from mushrooms and botanicals is caffeine-free. If the blend also includes tea leaf or coffee, it will contain caffeine from those. Our MycoBrew blends are naturally caffeine-free.
What is the best caffeine-free tea for the evening?
Chamomile, rooibos and honeybush are popular choices, as is a calming mushroom blend such as our Reishi tea. Pick the flavour you enjoy most, and brew it slowly as part of a wind-down routine. If you have ongoing sleep problems, speak to your GP rather than relying on a tea.
Is caffeine-free tea safe in pregnancy?
Caffeine-free infusions are often suggested as an alternative to caffeinated drinks, and NHS guidance recommends keeping caffeine to 200mg a day or less. However, some herbs lack safety data in pregnancy and breastfeeding. Check any herbal or mushroom product with your midwife, pharmacist or GP first.
