As with normal filter brewing, following a specific recipe is important, if not more so because of the addition of ice. Trends toward the widespread use of electric vehicles and renewable energy sources all point to continued growth in copper demand. This demand will be met mainly by new primary copper production, with recycling expected to contribute significantly to copper supply. Significant quantities of copper ore are presently mined from porphyry deposits in which typically, near-surface copper oxides are recovered hydrometallurgically by leaching, solvent extraction and electrowinning, whereas the deeper copper sulphides are only amenable to milling followed by pyrometallurgical processing and electrolytic refining. The Chilean copper porphyries together are the largest group of operating copper mines and are likely to remain so into the future. However, several of these deposits are forecast to show increasing levels of arsenic-bearing minerals, such as enargite. As mature copper mining districts exhaust the near-surface oxides and higher-grade sulphides, individual mines will need to adjust their operations accordingly. However, it is considered that due to such changes, re-engineering efforts might be more economically coordinated across several mines, to collectively handle the evolving ore feeds.

It’s also interesting to see forward-thinking coffee professionals experimenting on this classic technique to innovate with cold coffee flavour profiles. For example, Matteo tells me that he was impressed by the work of 2019 Brewers Cup Champion Lewis Maillardet.Below you can find an example flash brew recipe using 30g of coffee, which will yield 500g (around enough for two cups): Just as with filter coffee, it’s important to experiment with your recipe and tailor all the different brewing variables Reed, S.J.B.

Saturate the coffee bed with your water (60ml to 90ml), and let the coffee bloom for 30 to 45 seconds.H. Zhang, Y. Wang, Y. He, S. Xu, B. Hu, H. Cao, J. Zhou, and G. Zheng, Miner.
