I am making rum using my great grandfathers still and recipe. I used six pounds of sugar and six pounds of molasses, as well as some fruits. The mash has been fermenting for 18 days. The yeast has been active with no sign of stopping soon. The hydrometer reading has not changed much in the past 4 days. The airlock is still in place and bubbling like crazy. Should I let it keep going? Some buddies of mine have never had fermentation go past two weeks. I live in Colorado, does the elevation effect this? Thank you in advance for any advice you can give me.
I think your original reading may have been a bit off… 6 pounds of sugar and 6 gallons of water without the fruit or the molasses would have been 1.046
can you take a picture and circle the area on the hydrometer that the original reading was?
If the hydrometer is at 1.000 it should look like this
If it does look like that- she is pretty much done fermenting.
