01Beginnings
Masters of Rosin is a competition with one purpose: finding out who makes the best hash rosin. Its organizer, David Madilyan, said the event runs a single category and deals only in rosin, and he pointed to that narrow focus as what makes it different1. He said the guiding question has been the same from the start: who has the best rosin in the world1.
Less is known about how it began. The sources used for this page do not give the founding date, the founders or the original location. The only clue to timing is the organizer's comment, quoted in a December 2024 article, that the competition was in its eighth year1. Counting backwards from that would be guesswork, so this page gives no start year. This page is about the hash rosin cup only, not other events with similar names.
02The story so far
In 2024 the competition held two editions. The New York City edition came first, and a Leaf Magazines write-up described it as a strong start to the year1. A Los Angeles edition followed later that year and was the competition's first on the West Coast1. The article ran in the December 2024 issue of California Leaf and places the LA event only in "last month", so the exact month is unknown1.
The write-up says more than 50 competitors took part in Los Angeles1. The event had three stages. Competitors handed in their entries at the Cookies dispensary in Maywood, a party followed at the Astor Club, and the judges finished up in a session at a private home whose address was kept secret1.
03Culture and community
The judging panel was put together to show how international the event is. It included a judge from South Africa, named as Joe from Big Green Budha, and Lil Big Smoker from Brazil, along with JP Toro, Scott Deppe of Mothership Glass and others1.
The Alchemist played a set at the Astor Club party, and the writer described the room as full of energy1. Rare glass rigs were set out on the tables as if they were artworks on display1. The writer said the event felt less like a cutthroat contest and more like a family get-together, and called it authentic and respectful for an industry that is growing fast1. These are one writer's impressions.
04Where it stands now
The latest information available comes from the Leaf Magazines article, first published in the December 2024 issue of California Leaf1. It says the competition was in its eighth year and held editions in New York City and Los Angeles in 20241. The sources used for this page cover nothing after that. For later editions, new locations or format changes, check with the organizers.
05What's next
The organizer said there are no plans to change the single-category, rosin-only format1. No other plans have been announced, and the sources used for this page give no dates, locations or new editions.
