When it comes to pressing rosin, there's a lot of talk about the temperature, time, the force used to achieve the best results. While those are all important in the process, it seems there's no talk about the amount of material we press and how that affects yield. You, me and 95% of people looking for a rosin press have saw videos of rosin rivers flowing down the parchment so beautifully. Once you have a rosin press you'll attempt to replicate what we saw by pressing an excessive amount of flowers. While it seems to work, it destroys your yield. Let's face it; most of us want the rosin rivers for the pictures and videos for social media. Well is the validation you receive worth a 5% loss on yield? For most people, it's not. So is there a sweet spot for the amount of flowers you can press? Below we go over what we experienced in pressing different amounts and how it affects our yield.
3.5 Grams of Flowers
While 3.5 grams of flower seems small the yield seems to make up for it. We tested 3.5 grams four times and had an average return of 28%+. We had the temperature of our rosin plates at 195F.
5 Grams of Flowers
With 5 grams of flower we saw a slight drop in yield. Five grams was pressed four times and had an average return of 25%+. The temperature of our rosin plates at 195F.
10 Grams of Flowers
With 10 grams of flower, we saw a significant drop in yield. Ten grams was pressed four times and had an average return of 20%. Again, the temperature of our rosin plates at 195F.
Each sample was press only once, under 4 US tons to ensure a consistent standard for the test. We slowly increased the force over two minutes, maxed out at 4tons. While this post is not a guideline, it should give those looking to maximize yield a place to start.
