Recently ordered some Campos beans (am recovering from surgery so doing up roasts would be a bit too strenuous at the moment), and emailed them asking about what they'd recommend for rest times of their beans and also brew ratios (I ordered the Superior Blend and a washed Colombia Rodriguez Ospina). Got back an incredibly helpful response, just thought I'd share it if people were curious about their beans etc: ----------------------------- Hi Simon, Thank you for taking the time to get in touch. In our stores we typically age our coffee 10 days after roasting. Having said that, you can use coffee almost immediately, the most notable difference will be an increased level of gassiness in the crema and a slightly increased degree of brightness. The coffee will retain much of its best flavours weeks after roasting but will gradually lose some of that vibrancy. We do indeed have roast dates on all of our coffee. With regards to rations for the specific beans you have, the below info will help- For Superior we recommend: A ratio of 1:1.7@35s. More specifically, using an LM 21g basket we use Dose: 23g Yield: 40g Time: 35s For Ospina we recommend: 1:2@30s Dose: 23g Yield: 46g Time:30s You can adjust those specific numbers using that ratio to suit your basket size. Typically, the range to work with is +/-10% of the basket. So if you are using a 20g VST, you can work between 18-22g. We use a dose of 23g in a 21g basket for a full flavour, especially when splitting between two coffees and also for a greater structure and strength in the coffee puck during extraction.
