What grind size should I use?Updated 3 days ago

For our Cold Brew Maker, we recommend a coarse grind level. However, please understand some finer grounds seeping through the filter is inevitable as the filter holes must be big enough for the best brewing. (To make sure enough flavor is extracted in the coffee within 12-18hrs) What you may try to eliminate this is using the extra coarse ground. Or before putting the filter back in the carafe and filling up your cold brew maker with water, shake and rotate the filter with the coffee grounds in it to allow for the smaller finer grinds to come out first.
