Differences and Similarities for Rosin Pressing

The art of pressing rosin is constantly going through innovations as we learn more and more about the cannabis plant and what makes a high-quality rosin extraction. Traditionally, rosin press bags are filled, closed on both ends, then laid flat onto the plates of the rosin press. Nowadays, you may see some pressing flower rosin using other techniques like Bottle Tech or Chottle Tech. Both are used exclusively for pressing flower rosin. They are not suitable for pressing hash rosin. In this article, we will discuss the similarities and differences between Bottle Tech and Chottle Tech. We will also tell you how to properly use each technique!

Bottle Tech Style Pressing

Bottle tech style pressing has become a popular technique used by those who press flower rosin. When pressing Bottle Tech Style, the rosin bag is placed vertically on the rosin press plates. This differs from the traditional horizontal lay. The bag will resemble a cylindrical bottle on the press plates, hence the name Bottle Tech. 

The benefits of using a vertical rosin bag placement as opposed to the traditional horizontal placement comes down to surface area and expansion. Bottle tech style uses less surface area than traditional pressing. Not only that, but the bag will expand less. This means that as pressure is applied, a bottle tech style bag will remain at a near constant pressure throughout the bag. More control over pressure can mean higher yields. When pressing with a traditional horizontal bag, the bag expands relatively more than with bottle tech. Bag expansion means the pressure will decrease. 

To press flower rosin using Bottle Tech Style, fill your rosin bag with small to medium sized buds as you usually would. Be careful to avoid air pockets and overfilling. It can help to push in the bottom corners of the rosin bag (see the picture above).

Leave about ¼ inch of space at the top to “close” the bag. To close the bag at the top, simply fold the sides inward towards the center. Once your bag is filled and closed, place the bag onto the center of the rosin press place. Now you are ready to press flower rosin using Bottle Tech Style!

Chottle Tech Style Pressing

Chottle Tech is similar to Bottle Tech in that it utilizes a vertical placement of the rosin bag. The difference between Bottle Tech and Chottle Tech is that the ends of the rosin bag are left open when using Chottle Tech. Instead of buying individual bags like you would need to for Bottle Tech, you can purchase sleeves of nylon mesh that can be cut to any size you want when using Chottle Tech.

Because the ends of the sleeve are left open, there is less mesh material for the rosin to get stuck in when pressing. This could increase yields even more than using Bottle Tech. You, of course, run the risk of some flower material finding its way into your rosin because the flower is not fully enclosed, but with enough practice, you will be able to avoid that. 

To press flower rosin using Chottle Tech, cut the length of the nylon mesh you would like to use (usually around 4 inches will work well) and pack it with small to medium-sized buds, being careful to avoid air pockets. Do not close either end of the sleeve. Once packed, place the sleeve onto the center of your rosin press plates. Now, you are ready to press using Chottle Tech!

Summary

Bottle Tech and Chottle Tech differ from traditional rosin pressing in that the rosin bag is placed vertically on the rosin press plates rather than the traditional horizontal lay. This decreases surface area and allows for better pressure control. While Bottle Tech has 2 closed ends like with traditional rosin pressing, Chottle Tech leaves both ends open. This can help to increase yields, but you risk allowing some flower material to escape and end up in your rosin.
