Amstelzwam Mushroom cafe

will you grow a mushroom grower ? 

getting started as a mushroom farmer 

With the mushroombox you can grow oyster mushrooms at home on your own coffee grounds or old tea bags. From a full bucket you can harvest 2 to 3 times.  And then you just start it up again (with part of the old content). This way you can always serve your friends the tastiest mushroom dishes.

why an empty plastic bucket?

Because we want you to use your own coffee grounds, because then it is local. Because the bucket is made of recycled plastic, you can use it more often

healthy

Oyster mushrooms are very healthy mushrooms. They lower cholesterol and have an anti-diabetic effect. They contain fibers, vitamins, minerals and antioxidants. They contain no fats and hardly any calories.

super fresh delicious

This mushroom is, besides being super fresh, also super tasty. It has a meaty structure, contains good vegetable proteins and tastes delicious. Fry them in oil on high heat with a little pepper and salt and it tastes just like meat. That is why they also call the oyster mushroom the steak among mushrooms. But the oyster mushroom is also very suitable processed in pasta, risotto or in soup. Look at www.oesterzwammen.nl for even more recipes

wat is a mushroom?

from 'franjekelkje', to exotic 'reikhalsje'

There are a few million mushrooms in the world, and on average seven new species are discovered in the Netherlands each month. They all get a name and not a Latin name as in the past, but a newly invented name. What name would you give the mushroom?

We eat the mushroom and the mushroom eats the coffee grounds

Oyster mushrooms are edible mushrooms that naturally occur on hardwood in the forest. It is also possible to grow them in a bucket with a closed lid on coffee grounds or tea leaves.

what is food waste?

do you know.....

• Did you know that the average Amsterdammer drinks 3.2 cups of coffee per day? That is easily 6 million kilos of coffee per year. That is 550,000 buckets of coffee grounds. That is a stack of buckets 187 km high. That is 18,700 times the Adam Tower on top of each other.
• Only 0.2% of each coffee bean ends up in your cup. The other 99.8% is thrown away. Not if it is up to Amstelzwam. Why? The coffee grounds are not waste - they are perhaps even more valuable than the coffee itself! You can grow great oyster mushrooms on them!
• The big advantage is that while making a cup of coffee you pasteurize the coffee grounds, after which they are clean. This way you can start growing oyster mushrooms immediately after drinking coffee - without wasting any more energy.

mushroombox

By growing fungi in a mushroom box on the counter, you don’t need any extra water to grow oyster mushrooms if your coffee grounds are moist enough. It also doesn’t cost any fossil fuels to transport the products. Moreover, you will be amazed by the ‘enchanting cycle of the fungus’.

the coffee cycle

These Mushroom Cafés are not only intended to help you build a mushroom box for your kitchen, but also to put a stop to the waste of raw materials!

the coffee cycle

By using your coffee grounds as raw material for a new life of oyster mushrooms, you turn waste into food again. You prevent a lot of water waste, CO2 production and especially a lot of food kilometers (12,000 km per meal!). And at the end you also have fantastic fertilizer for the (school) garden. The coffee grounds are an extremely good fertilizer after the growth of the fungi. This approach is also called the circular economy.

grow your own oyster mushrooms with coffee grounds or tea leaves

1. Bring a super-clean yoghurt cup with lid (pack in a clean plastic bag)
2. Bring about 2 cups of fresh coffee grounds in a clean plastic bag (max 1 day old)

step #1

Use a punch to make 2 holes in the lid of the yoghurt cup

step #2

clean the cup and lid thoroughly with hot water. We work sterile and also ensure clean hands

step #3

dry the growkid and stick the papertape  (leucopor) on the both holes

step #4

add micelium to the grow kit and break it into small pieces

step #5

add coffee grounds to the grow kit and mix it together.

watch out because the coffee grounds should be dark brown in color. If it is too dry add water, but not too mutch. Otherwise other mushrooms will pop up. 

step #6

add coffee grounds to the grow kit and mix it together.

watch out because the coffee grounds should be dark brown in color. If it is too dry add water, but not too mutch. Otherwise other mushrooms will pop up. 

step #7

Then you wait a few days until it molds, but be careful, the mold must be white. Other colors of mold you remove hygienically with a clean spoon

step #8

keep adding the coffee grounds when a layer of white mold appears (4 days) until the grow kit is full

step #9

wait at least 2 weeks until mushrooms start growing through the holes. When they are big enough, harvest them from the grow kit and remove the legs so that more mushrooms can be formed in a few weeks

step #10

and now it's time to cook or bake them and make a delicious dish out of it. Enjoy your meal

step #11

Did you enjoy doing it? Then start over! With 20% of the substrate you can start a new growkid. You hand out the rest during a mushroom café where you ask the participants to bring a yoghurt cup with lid and coffee grounds. This way you get more supporters of a circular world

what is a food-chain?

the foodchain

• How do you think your topping got onto your sandwich?
• What does it take to get that topping onto your sandwich?
• Who/what is involved?

from farmer to supermarket

Oyster mushrooms can easily be grown in your own home, just like a farmer grows his mushrooms in his nursery. It is done in a completely different way and that is not on coffee grounds, but straw and in dark spaces

Where does your food come from?

We also eat other products such as chicken, vegetables and fruit. How do you think chocolate sprinkles can end up on your sandwich? It comes from the supermarket, but what happened for that? What is needed and who is involved?

3 food chains

which food chain is the longest?

• your oyster mushroom that you grew in your own home
• the mushroom that the farmer grows
• the kiwi that comes from New Zealand
