Stop guessing. Hydrometer, refractometer, pH, SO2, acid — the instruments that turn a hobby into a craft.
You can make decent wine with one hydrometer and a calendar. You can make great wine with five instruments and notes. This bundle is the second path.
Buy them as you graduate, not all at once. A refractometer earns its keep on batch two. A Vinmetrica earns it on batch ten.
