ok so I use the hydrometer to take the gravity of my cider and dosent sink enough to even reach the scale. I add a cup of sugar and it goes to the same spot. Am I not knowing how to use it or is it defective?
Maybe the cider is at an astronomical gravity? Try using a quart of room temp water and a half cup of sugar or so, dissolve and then test that? ...Maybe a note to self to have two hydrometers for co-witnessing!
