Maybe dental floss? Couldn't the weight of the string be calibrated out? Fill the carboy to the five gallon mark with plain old tap water. As a control, measure the tap water without the string attached. Then measure tap water with the string attached to find an offset. Or something like that.
On a side note. I've never had any luck trying to drop a hydrometer into a fermenter. Very difficult to read.
If the floss will grab and hold the hydro that would be killer! Now I will have to give it a try tonight. Could be a new way to check 1 gallon batches than use an unreliable refractometer calculation.
OP what is your recipe, OG and Yeast? Wonder if you might be ok to let it sit for 3 weeks before bottling. I definitely under stand if you do not want any bottle bombs and want the gravity readings to confirm.
