	Grape characteristics
Name	Arinto
Type of grape variety	White
Description	Arinto is a very versatile grape variety and, for this reason, it is grown in almost every wine region. In the Vinhos Verdes region it is known as Pedernã. However, it is in Bucelas that Arinto gains notoriety, being considered the region’s “queen” grape variety. Arinto’s bunch is big, compact and made up of small or medium-sized, yellowish berries. This grape variety is usually used in the production of blend (more than one grape variety) and sparkling wines. In the Bucelas region, Arinto produces high acidity monovarietal wines (single grape variety), which are citrine coloured and markedly floral and fruity (when young).
