Pick off the berries from any remaining stems.
Smash the berries in the molcajete (mortar and pestle) until the berries are in juicy chunks. You will hear a squishing sound that indicates the berries are ready to be added to the water.
Fill the smashed berries in a clean jar of the water.
Mix up the berry and water mixture with a large wooden spoon and place a cheesecloth or mesh bag over the top of the jar.
Let the berry and water mixture sit somewhere dark for 5 days. In a cupboard is ideal.
Check the berry and water mixture each day to make sure there is no mold and/or bugs getting in. Taste it once in awhile to make sure it is tasting fermented (it will be sour and bubbly).
Strain out the berries by placing a smaller glass jar underneath with a fine mesh colander on top (or cheesecloth). Pour out the berry and water mixture so only the spritzer goes into the glass and the fermented berries stay in the colander.
Mix well and add honey (if desired).
Refrigerate right away (if not doing the double fermentation) and enjoy!
