Best New Rosin Brand
In House
There’s no way to hide mediocre rosin in Denver, perhaps the most evolved and competitive hash market in the world. Frosty buds and purple colors won’t save you, leaving only aroma and consistency to reveal a product’s quality – and In House has been tops at both since bursting onto the scene in 2024. Over the past year, the new Denver hash maker excelled in cold cure and jam, squeezing top-tier goo out of classic strains like Sour Diesel while pushing boundaries with modern combinations such as Captain Insano and Maple Dunks. In just a short amount of time (and despite its very un-Google-friendly name), In House has become peers with a handful of Colorado’s best rosin makers and expanded into new product territories. In early 2025, the company released a more affordable mixed-micron line and a take on the elusive piatella, a form of cured rosin made from full-melt bubble hash. That level of creativity and expansion is almost impossible to keep going, but we’re excited to see what’s next for this low-key rosin lab that lets terps do the talking.
