9 August, 2025Identify unknown grape varieties with DNA profiling
Using 12 genetic DNA markers (microsatellites), I can identify your unknown vine by checking its profile against my extensive database composed of more than 3000 grape varieties from all over the world.
Using 50-60 genetic markers, I can discover unsuspected parentages and reconstruct unexpected genealogical trees.
