I've had a search but was unsuccessful; I know about weighing for brewing habits but what about checking purchases?
I appreciate that turning a blind eye depends on the amount of tea purchased.
I've weighed some of my smaller tea purchases and found 500mg -700mg less in some.
Do you bother contacting the vendor after finding a discrepancy?
Hopefully the poll is thorough enough and clear!
do you usually calibrate your weighing scale regularly? some times a bit of imbalance or tilt that develops over the years will result in non-linearity in weighing.
