Embodiments of the present disclosure include a matrix of raw materials, also referred to as a poly-grain grind matrix. In some embodiments, the matrix of raw materials may form an interlocking network of varied particle grind sizes that allows the particles to nest and interlock with one another when packed into an extraction vessel, so that most, but not all of the interstitial spacing within the matrix of raw materials is closed. Additionally, the varied particle sizes may be selected by pre-determined weight ranges and size classifications so that the particle grind sizes achieve the desired consistency uniformity. This may allow the network of particles to act as its own best filtering agent during the extraction process. Moreover, the nesting and interlocking network of the particles within the matrix of raw materials may allow the particles to be effectively packed within the extraction column, thus allowing for an efficient and high quality extraction to be performed consistently each and every time.
