FILTERING / FINING

CHOICES (3)?

REASONS (3)?

INFLUENCE ON STYLE / QUALITY / PRICE (2)?

A

CHOICE: 1) Sedimentation

2) Fining
3) Sterile Filtration

REASON: 1) Sedimentation (racking) = gentlest / least manipulative form of removing sediment. Filtering/Fining wants to be avoided.

2) Filtering = clear+bright wine.
3) Sterile Filtration = avoids risks of developing in bottle.

INFLUENCE: 1) Maintains quality + style

2) Additional $$$ as wine must be stored until it is cleared of sediment.

HARVEST

CHOICE (2)?

REASON (2)?

INFLUENCE ON STYLE / QUALITY / PRICE (3)?

A

CHOICE: 1) Hand Harvest

2) Harvest in coolest hours of morning/evening.

REASON: 1) Sorting in vineyard = only healthy, fully ripe bunches.

2) Coolest conditions = less oxidation + microbial spoilage.

MATURATION VESSEL

CHOICES (2)?

REASON (3)?

INFLUENCE ON STYLE / QUALITY / PRICE (4)?

A

CHOICE: 1) Small, new oak barrels.

or

2) Large barrels / Stainless Steel

REASON: 1) Oaked style is desired: Oak flavors + mild oxidation.

2) Wines begin to clarify naturally due to time of maturation
3) Neutral vessels allow flavors to integrate + fermentation esters lost.

INFLUENCE: 1) Small barrels = deeper color / fuller body / vanilla+spice notes / development of tertiary characteristics.

2) Added cost of barrels + monitoring / racking wine = $$$
3) Neutral vessels = best expression of primary fruit flavors.
4) Large vessels = winery space needed, appropriate temp + monitoring of racking.

2) Retaining solids increases complexity of aromas.

INFLUENCE: 1) Clarifying must = less post-fermentation clarification needed, retaining delicate flavors + aromas.

2) Increased complexity of aromas (not just fruity) + lower sulfur compounds = higher quality.
