Among the various techniques used to improve yield and quality, the Bottle Tech method stands out for its simplicity and efficiency in pressing flowers. This blog will guide you through the Bottle Tech technique, focusing on correctly packing a filter bag to ensure optimal results when pressed in a rosin press.

What is the Bottle Tech Method?

The Bottle Tech method is a technique used in rosin pressing where cannabis material is packed vertically into a filter bag, mimicking the shape of a bottle. This method allows for better control over pressure distribution during the pressing process, resulting in a more efficient extraction.

Why Choose Bottle Tech?

1. Maximized Yield: The vertical packing minimizes the contact area with the plates, leading to a more concentrated extraction. This translates to less pressure required for the same amount of material and a considerable increase in return.
2. Better Quality: By reducing the surface area, there is less risk of plant material contaminating the rosin.
3. Ease of Use: The Bottle Tech method simplifies the packing process, making it accessible even for beginners.

Step-by-Step Guide to Packing a Filter Bag Using Bottle Tech

Step 1: Prepare the Flowers

Start by ensuring your cannabis material is adequately prepared. If you are using flower, break it into smaller parts, but avoid grinding it too finely.

Step 2: Pre-pressing

Place the broken-down flowers inside the pre-press mold and then compress them with your hands or with the help of a mold presser.

Step 3: Packing the Filter Bag

• Turn the Bag Inside Out: This prevents the seams from trapping rosin and reduces the chances of rupture.
• Place the Block: Carefully place the compressed block inside the filter bag. Choose the appropriate bag size depending on the pre-press mold you are using.

• Fold the Corners: Fold the corners inward to create a flat and even bottom. Then, using the pre-press mold, press the block to the bottom and adjust the corners until you achieve perfect packing.\

• Trim the Excess: With the block at the bottom of the filter bag, leave approximately 25mm of free space and trim the excess bag material.

• Top Packing: Like wrapping a gift, pack the top part. Take a few moments on this step, continuously pushing the block to the bottom and carefully folding each corner until you get a perfect block.

• Adjusting the Plates: Before inserting your compact package, close the plates, leaving them the same size as the filter bag so it fits tightly and the top packing doesn’t come apart when inserted. Leave the tip of the bag pointing out of the plates.

Mastering the Bottle Tech technique simplifies the process and saves you time, making it accessible for beginners. By following these detailed steps, you can maximize your yields and obtain pure, high-quality rosin. Experiment with different temperatures and pressures to find the optimal point for your specific material, and enjoy the process of creating top-tier rosin. Happy pressing!
