It has been really hot lately…record-breaking hot. We have had a lot of fun in the office over the past two weeks experimenting with a DIY Cold Brew Coffee Maker. This Cold Brewer is made with a mason jar, Aeropress, and a water bottle. Here is an image of the Cold Brewer and the instructions from our Prima Coffee Facebook page.
DIY cold brew for $30! You’ll need: Aeropress with 2 filters, bottle, sewing needle, sharp knife, water, ice, and coffee.
 Empty bottle and cut off bottom.
 Remove bottle’s cap and puncture w/ needle. Replace cap. Test flow by filling w/ water and watching rate, aiming for about 40 drops per minute.
 Wet filter and assemble Aeropress, filling w/ 45 g (9 tbsp) of medium-fine ground coffee.
 Moisten grounds and stir gently, subtracting water used from total water dose. Level coffee bed with finger.
 Trim second filter to fit inside of Aeropress and place atop coffee bed, pressing softly to level.
 Place Aeropress on jar and mount bottle on top.
 Fill bottle w/ 300 g (10 oz) water and 200 g (7 oz) ice.
After bottle has emptied, serve coffee over ice.
