White wine steps
GRAPES - grape sort - crush fruit - skin contact —- PRES FRUIT - clarification - ALCOHOL FERMENT – stainless - oak - inert–RACK OFF LEES - mlf - blend - age (inert, oak, lees) — blend again - PACKAGE - WINE FOR SALE
what are wine making choices for less aromatic white grapes?
- crush vs whole bunches
- controlled exposure to oxygen to improve ability to age
- clarification–> settling method (may choose to leave matter for texture)
- fermentation - stainless, concrete, oak,
- MLF
describe the Italian style Pinot Grigio
Produced in Alto Adge, Trention, Friuli-venezia
-dry style
-premium = great flavor concentration– Northerly Alpino
VENETO -pale skin, fleshy, neutral, high yields, early harvest – high volume
describe the French style Pinot Gris
- early ripening in warm climate
- dry or off dry
- often with oily texture
- ripe, tropical fruit, ginger, honey

what is the goal in producing wine w/ less aromatic grapes?
the aim is to enhance the base material provided by the grapes
- achieved by doing relatively little, pure in form
- other wine makers may choose techniques that add complexity and texture
How to handle aromatic grapes during the wine making process
- crushed fruit or whole bunches that are loaded into the press
- little skin contact or none
- gentle clarification used
- inert vessels for fermentation
- cool temp
- see little post fermentation choices: chips/ staves, MLF avoided by adding SO2
How are sweet wines made?
1) stop fermentation add grape spirit by adding SO2 or chill wine
2) add sweet component
3) start with a concentrated sugar juice
list ways to create concentrated sugar grape juice prior to fermentation?
- noble rot
- drying on vine
- drying after picked
- freezing grapes
Where is Riesling grown
Germany- premium has balanced acidity Australia- range of sweetness Australia- Clare and Eden: dry, lime France, Alsace- Dry, late harvest, boytrytis Washington: dry NZ & NY: fruity and off dry
Characteristics of Riesling
- tolerant of cold winters: buds late in spring
- cool climate: green fruit & floral
- warm climate: citrus stone fruit
- left on vine–> accumulates sugar w/o lose acidity
- aged–> develop honey & toast and petrol
