Café des Guerriers review
Café Parfait, from the French brand Café des Guerriers, is an organic instant mushroom coffee: 3.5 g of coffee, four mushrooms and two plants per cup, in four flavours. It is a recipe generous in mushrooms and certified organic, with the caffeine of half an espresso. Brainstoorm makes a different choice: no coffee, extracts with their ratio written down, 20 mg of caffeine, and the right to open the pouch before deciding. Here are the two recipes, line by line.
Who is writing: Mush n Go makes Brainstoorm, a direct competitor of Café des Guerriers. This page compares what each brand states on its website and, for Brainstoorm, the technical data sheet from our contract manufacturer. Figures recorded on 19 October 2026.

Brainstoorm coffee flavour
Lion's mane, cordyceps and chaga from the fruiting body, maca, ashwagandha and roasted chicory. The taste of coffee, without the jitters.

See the choc version →Our verdict in brief
An organic coffee rich in mushrooms, or a light cup with standardised extracts.
Café Parfait and Brainstoorm have a lot in common: mushrooms from the fruiting body, ashwagandha, maca, and both are made in France. Café Parfait puts in more mushrooms by weight and carries the organic label; it also keeps the coffee, and its caffeine. Brainstoorm contains no coffee: it relies on concentrated extracts, vitamin B5 dosed at 100% of the reference intake and 20 mg of caffeine.
- Brainstoorm is for you if you want to cut your caffeine right down (20 mg), know the ratio of every extract, and be able to open the pouch before deciding whether to keep it.
- Café Parfait is for you if organic is your first criterion, if you want to keep the taste and caffeine of a real coffee, and if you like choosing between four flavours.
- On price, Café Parfait is slightly cheaper: €1.30 per cup as a one-off purchase versus €1.42 for Brainstoorm, and €0.71 versus €0.78 at the best subscription price.
What is Café des Guerriers
A young Paris-based brand, specialising in mushroom coffee.
Café des Guerriers is a French company founded in 2020 and based in Paris. It presents itself as a specialist in “adaptogenic coffees” and sells a single mushroom coffee, Café Parfait, in four flavours, as well as a mushroom chocolate and a mushroom protein. The coffee is certified organic by Ecocert and packed in pouches in France.
The ingredients in detail
What is in a cup of Café Parfait.
The product page publishes a table per 5 g serving, ingredient by ingredient: that is welcome transparency. It specifies that the mushrooms come from the fruiting body. It does not, however, give the ratio or the beta-glucan content, except for the chaga, standardised to 30% polysaccharides.
| Per 5 g serving | Stated amount | Note |
|---|---|---|
| Organic instant coffee | 3,500 mg | arabica and robusta |
| Lion's mane | 500 mg | fruiting body powder |
| Cordyceps | 300 mg | fruiting body powder, species not specified |
| Chaga | 300 mg | extract, 30% polysaccharides |
| Reishi | 200 mg | fruiting body powder |
| Total mushrooms | 1,300 mg | our own total |
| Ashwagandha | 100 mg | whole plant, withanolide content not stated |
| Maca | 100 mg |
Source: “Le Café Parfait” product page, nutrition table and FAQ on cafedesguerriers.fr, recorded on 19 October 2026. The product page FAQ refers to mushroom powder; another page refers to extraction. The table is the same for all four flavours and does not mention any flavouring. Depending on where you look, the brand states 1,500 mg or 3,200 mg of adaptogens per cup: we use the table.
Extract or equivalent
Two numbers for the same mushroom: how to read them.
On a mushroom coffee label, the same ingredient can appear with two very different weights. Both are correct; they do not measure the same thing. Café Parfait mainly states powder weights; Brainstoorm states extracts, with their dried-mushroom equivalent. The two numbers cannot be compared directly: we give both for Brainstoorm.
The extract is what is in the cup
An extract is a concentrate. With a 10:1 ratio, it took 10 g of dried mushroom to obtain 1 g of powder.
The equivalent is the starting weight
“1,000 mg dry equivalent” with a 10:1 ratio means 100 mg of extract in the cup.
The part of the mushroom matters
The fruiting body is the mushroom itself; the mycelium is its network of filaments. Both are used, and a clear label says which.
The rule for comparing
Always the same column on both sides: extract against extract, equivalent against equivalent. That is what the following table does.
Dosages compared
Brainstoorm and Café des Guerriers, line by line.
For Brainstoorm, the table gives the actual weight of extract and then, in brackets, the dried-plant equivalent. For Café Parfait, the stated weight. Brainstoorm coffee flavour: 6 g serving. Café Parfait: 5 g serving.
| Per cup | Brainstoorm coffee | Café Parfait |
|---|---|---|
| Caffeine | 20 mg, microencapsulated | 48 to 60 mg depending on the page, from coffee |
| Lion's mane | 100 mg of 10:1 extract (1,000 mg) | 500 mg of powder |
| Cordyceps | 250 mg of 4:1 extract (1,000 mg) | 300 mg of powder |
| Chaga | 20 mg of 50:1 extract (1,000 mg) | 300 mg of extract, ratio not stated |
| Reishi | absent | 200 mg of powder |
| Maca | 375 mg of extract (3,000 mg) | 100 mg |
| Ashwagandha | 40 mg of extract | 100 mg |
| Vitamin B5 | 6 mg, 100% of the reference intake | absent |
| Base | roasted chicory 3,500 mg, acacia 889 mg | organic instant coffee 3,500 mg |
| Part of the mushroom | fruiting body | fruiting body |
| Organic | no | yes, certified |
| Sweetener | xylitol | none |

By weight, Café Parfait puts more mushrooms in the cup, and it adds reishi. Yet a weight of powder and a weight of extract do not measure the same thing: 375 mg of 8:1 maca extract in Brainstoorm represents 3,000 mg of root, versus 100 mg in Café Parfait. Brainstoorm writes down the ratio of each extract and provides 6 mg of vitamin B5, i.e. 100% of the reference intake: it contributes to the reduction of tiredness and fatigue and to normal mental performance.
Caffeine
Half an espresso on one side, 20 mg on the other.
Café Parfait contains 3.5 g of instant coffee per cup. Its caffeine is stated as 60 mg on the product page, around 50 mg on the label and around 48 mg in the website FAQ. That is a little over half an espresso, which contains around 80 mg according to the European Food Safety Authority.
Brainstoorm contains no coffee. Each cup provides 20 mg of NewCaff® microencapsulated caffeine, coated so that it is released gradually, and its taste comes from roasted chicory.
One cup a day
Café Parfait: 48 to 60 mg. Brainstoorm: 20 mg. The EFSA benchmark for an adult is 400 mg a day, from all sources combined.
With your usual coffees
Two espressos plus one Café Parfait: around 210 to 220 mg. The same two espressos plus one Brainstoorm: around 180 mg.
In the afternoon
At 20 mg, a cup of Brainstoorm after lunch weighs four times less on your evening than an espresso.

Price, shipping, guarantee
The price per cup, and what the guarantee really covers.
Both brands sell in France, as a one-off purchase and on subscription. A pouch of Café Parfait contains 30 servings according to the product page; so does a pouch of Brainstoorm.
| In France | Brainstoorm | Café Parfait |
|---|---|---|
| 1 pouch, no subscription | €42.71, i.e. €1.42 per cup | €39.00, i.e. €1.30 per cup |
| 3 pouches, no subscription | €99.86, i.e. €1.11 per cup | €94.00, i.e. €1.04 per cup |
| Subscription, 1 pouch | €29.90 per month, i.e. €1.00 per cup | €29.00, i.e. €0.97 per cup |
| Best listed price | €69.90 for 3 months on subscription, i.e. €0.78 per cup | €64.00 for 3 pouches every 90 days, i.e. €0.71 per cup |
| Shipping | free from €59 | free from €45 and on subscription |
| Money-back guarantee | 60 days, even once the pouch is open | 60 days, product unopened and unused |
Prices recorded on 6 October 2026 on mushngo.com and on 19 October 2026 on cafedesguerriers.fr. Café des Guerriers return conditions as per the “Retours” tab of its product page; two of its subscription plans can be cancelled after 3 months.
Café Parfait is slightly cheaper in every scenario. The clearest difference lies in the guarantee: both brands advertise 60 days, but at Café des Guerriers the product must be returned unopened; at Mush n Go, you can open the pouch, taste it, and be refunded if it does not suit you.
Which one to choose
An organic mushroom coffee, or an alternative to coffee?
If you want to keep drinking coffee, organic, with a good dose of mushrooms and a choice of flavours, Café Parfait is a serious option. If you are looking precisely to move away from coffee, without the racing heart at 10 am or the slump at 3 pm, you are the person we created Brainstoorm for.
- 20 mg of caffeine per cup, released gradually: two to three times less than Café Parfait.
- Three mushrooms from the fruiting body, 1,000 mg of equivalent each, including 250 mg of cordyceps extract.
- Concentrated extracts, ratio written down, including 375 mg of maca extract, i.e. 3,000 mg of root.
- 6 mg of vitamin B5 in a single cup, i.e. 100% of the reference intake: it contributes to the reduction of tiredness and fatigue.
- No mushroom taste: roasted chicory brings the roundness and bitterness of a coffee.
- 60-day money-back guarantee: you taste, you decide.
More than 50,000 people have already replaced one of their cups with Brainstoorm, and rate it 4.8 out of 5.
Before starting either one
- Both products contain caffeine and are not recommended for children or for pregnant and breastfeeding women.
- Brainstoorm is not recommended if you have a thyroid, liver or heart condition: ask your doctor for advice.
- A food supplement is not a substitute for a varied diet. Do not exceed the stated daily dose.
