How to judge cannabis and hash

In the events such as the Cannabis Cup and the likes, there are many variations of cannabis strains that need testing in a short space of time. Sometimes over 30 strains in just four days, that’s a lot of smoking!

We’ll give you a quick overview of how to test for the best possible cannabis and hash so you don’t end up wasting your time and money on commercial, low quality produce when there’s so much excellent cannabis available in Amsterdam.

All Cannabis should be inspected before you buy, and certainly before it is smoked. Many coffeeshop in Amsterdam understand consumer needs and will often be able to provide you with a magnification equipment or something similar so you can do so. If they don’t, don’t be afraid to pull out your own magnifying glass or a loupe. Once you have the closest possible view of the cannabis, here’s what to look out for… Well-manicured and well-cured cannabis. Can you see a coating of sugary crystals? That’s a good sign. The mushroom shaped trichomes that contain THC should be amber in colour and well-formed, be aware of if they are smashed or seem discoloured. Also be careful in looking for mould. Mouldy cannabis is not safe and if you spot this, make sure to return the cannabis immediately and have the staff process a refund of your money.


Strains of cannabis can be smelt as soon as the bag is opened, however to get the best most accurate smell of your products to enable more accurate judging, you just first grind the bud using a hand grinder. Keep the bud remaining in the grinder and bring it to your nose to get a good whiff of the ground cannabis when you open it. Different strains have varying smells, some are spicy, some smell fruity. Haze strains have a unique pine smell to them, whereas a good blueberry haze should smell like, well, blueberries. If it smells green, it means it hasn’t been cured. If you come across uncured or wet cannabis, or if it smells mouldy or musty, don’t consume the cannabis.

The “dry toke” should consume your mouth with memorable flavours whether they are fruity, spicy or industrial and make you want to finish the joint. A well-cured spliff will be pleasant in taste and more-ish, as opposed to bad quality cannabis that will leave a harsh after-taste that nobody will want. A well-cured joint will be nice to smoke without the need to constantly relight.

All cannabis in Amsterdam will get you high, that is a given, however don’t just assume that when rating cannabis the only thing you should consider is how strong the cannabis is. Taste, smell and appearance are all equally as important, similarly to the best wine is not always that with the highest alcohol content. A good high should also not just be an instant high that is all a blur, it needs to be a memorable and soaring high that you can sit and enjoy. Although, even the good strains may have varied affects on different people and their bodies, once you find the high that feels good for you and the strain tastes great, use it to compare with others. If you then come across a strain that blows this out of the water, you then have something new to compare everything else to.


In the better coffeeshops that line the streets of Amsterdam, you will find imported hash from countries that have been making it for centuries such as Afghanistan, Morocco and India. It is the likes of these who have passed down the tradition of how to make hash. The plants are grown for a length of time dependant on how much hash they will provide and then the buds are passed off a by-product of the process and thrown away. Most Europeans – including the Dutch – tend to mix their hash with tobacco, but this can be ditched for a hash pipe, glass bowl or vaporizer. Just like everything else, once you purchase hash, it should be inspected closely to ensure what you’re paying for is of a high standard. To do this, start by rolling the hash around in your palm and warm it up, it should then start becoming softer. A decent hash should smell sweet and earthy, if there’s a pungent or mouldy smell, don’t smoke it. Two more determining factors of good hash are how it reacts when a flame is held up against it. A high quality hash should bubble and melt, whereas a bad hash will burn like coal with a strong smoke rising from it. And also streaks of white running through the hash. If these are visible it is a give away sign that your hash has been too moist for too long and therefore suffering.

Another hash you will find it bucket loads on Amsterdam coffeeshop menus is Nederhash. As you MAY have guessed from the name, Nederhash is simply hashish that has been produced in the Netherlands. The way this is made differs slightly and is typically been ice-water-extracted therefore making it really soft and basically liquid when it is warmed. Nederhash that has been made using the correct methods will bubble when it burns and gives off a tasty smoke and it will feel smooth. Nederhash when made at its best can sell anywhere between €40 and €50 per gram.
