Lumassina, white wine grape native to Italy. It is also called Acerbina (due to the high acidity of its wines).
Liguria | Lumassina has always been blended with other local varieties to produce simple everyday wines called vini nostralini. It grows mainly in the Savona countryside (around the towns of Noli, Spontorno, and Finale Ligure); monovarietal versions are rare.
Viticulture | Medium-large bunches, medium-small round berries. Late-ripening.
Wines | Colline Savonesi IGT.
Wine style | Low alcohol levels, tart green apple acidity (as mentioned above). White flowers, salty yellow fruit, herbs eg. thyme.
