I picked up a new-to-me Vinmetrica Pro Kit that came with several burettes - and I'm almost embarrassed to ask this but - what exactly are they used for vs. the pipettes? All the videos Vinmetrica has show testing manually without the stand etc. There's one video that shows the setup of the stand with the burette but not its operation. The instructions also mention how to set it up, clean the burettes etc but then only gives instruction for the basic manual kit. Is it simply to get a more accurate measure of wine and titrant to then release into the cup?
