The results table of the laboratory report: ochratoxin A 0.58 micrograms per kilo, four aflatoxins below the limit of measurement — The results table from our English summary of report B/0/09/2025/1242/F/1. The laboratory’s original follows it in the PDF.

Coffee is a crop. It is picked, dried, shipped and stored, and moulds can grow on any stored crop. Some moulds leave substances behind called mycotoxins.

The EU sets a limit for the best-known one in coffee, ochratoxin A: 3.0 micrograms per kilo of roasted coffee. We publish our number.

What the lab measured

0.58micrograms of ochratoxin A per kilo. The EU limit for roasted coffee is 3.0.

The laboratory is GBA Polska, accredited under number AB 1095. It finished the tests on 6 October 2025. It also looked for four aflatoxins, B1, B2, G1 and G2. All four were below the level the method can measure.

The Mushroom Coffee bag lying on a bed of ground coffee — Ground Arabica, Lion’s Mane extract and rhodiola extract. Nothing else.

What is in the bag

Speciality-grade Arabica from Brazil, medium roast, roasted in Poland and ground. Each 11 g cup also carries 500 mg of 10:1 Lion’s Mane fruiting-body extract and 130 mg of rhodiola extract.

That is the whole list. There is no sugar, sweetener, flavouring or creamer, and the 100 mg of caffeine in a cup is the coffee’s own.

How it drinks

Like coffee. You brew it in a cafetière, a moka pot, a filter or a pour-over: 11 g to 200 ml of water. A bag makes 30 cups at 83p each, and two bags bring that to 58p.
