Vini Flashcards
Which area starts harvesting first
Douro Superior (hotter)
What is the approach in fermentation for port
rapid extraction of colour and tannin (before addition of grape spirit which would stop this)
What is the usual amount of time for skin contact
48 hours
What are the 4 methods of extraction
Foot trading in Lagares
Autovinification
Remontagem (pumping over)
Mechanical treading
What is added to lagares
Sulphur dioxide
Tartaric avid is optional (to acidity)
Describe foot treading process
Fermentation starts soon after treading
Relies upon ambient yeasts
When fermentation is underway, the cap is pushed down
When enough e traction occurs, the partially fermented must is run off
What is an advantage of autovinifiers
Self-powered
Cheaper than lagares
How do autovinifiers work
Carbon dioxide produced powers the cycle
What is pumping over known as
Remontagem
Robotic treading machines were developed by which house
Symingtons
How do modern white port production methods vary from older ones
Old-extractive, oxidative
New- little to no skin contact. Temp controlled. Cultured yeast.
Sold unaged
Fermentation lasts longer to produce a drier style
At what point is the wine fortified
During fermentation, when the wine is at 5-8% abv
What is used to fortify port
Grape spirit (77% abv)
Where must the grape spirit for fortification come from
Any EU country
What ratio is the grape spirit added in
20% spirit to 80% must
