If you can put the grounds in a bag or filter, it'll save a lot of time in the future when you might want to filter it so it's not like drinking sand or silt.

Also if you choose to filter, know that filtering can take a long time because the smaller grounds can clog up the pores. So go from filtering course to fine eg. use a sieve, then cheesecloth, then paper coffee filters, etc. based on how filtered you want it or your patience
