Activated Carbon Coconut Based 12x40 Mesh

Coconut shell activated carbon for polishing spirit. This is the grade we run through the Filter Pro at Australian Home Brewing.

Why coconut

Coconut shell carbon is nearly all micropores, the tiny ones under 2 nanometres. That's the size of the compounds that make new spirit taste harsh: fusel oils, higher alcohols, aldehydes and sulphur notes. Coal-based carbon has wider pores, which suits colour removal in water more than it suits spirit.

Why 12 x 40 mesh

Every granule sits between 0.42 mm and 1.7 mm. Fine enough to give your spirit plenty of surface to touch and coarse enough that the bed won't pack down, channel or block a gravity column.

How to use it

·        Flush the carbon with about 8 litres of water before the first run. It's acid washed and pH neutral, so this is a quick rinse, not a twenty-minute dust bath.

·        The first 300 to 400 ml off the filter after the flush is water-heavy. Set it aside if you want to hold your ABV.

·        Go slow, carbon needs contact time. A slow drip gives a clean neutral spirit. A fast pour gives you back roughly what you put in.

·        Carbon fills up, then it stops. Use fresh carbon for each batch rather than pushing a second run through a spent bed.

Storing it

Carbon adsorbs whatever is around it, including shed air and moisture. Keep the bag sealed, or decant a working jar for the bench and close the rest up.
