Brandy Flashcards
(106 cards)
Cognac Houses
Remy, Hennessey, Martell, Courvoisier
Cognac Varietals
6 allowed, but Ugni Blanc (low sugar high acid) is dominant. Low sugar requires more concentration to produce Brandy, high acid provides microbial protection since SO2 must be avoided.
Cognac Crus
Grande Champagne, Petite Champagne, Borderies, Fins Bois, Bons Bois, Bois Ordinaires (production is concentrated around the town Cognac)
Bons Bois and Bois Ordinaires
together account for only 13% of production
Soils
Chalk and Clay provide good drainage with sufficient water retention and produce high acid grapes
Chaptalization in Cognac?
No. That would increase sugar which would mean less concentration to produce spirit which would be undesirable.
ML in Cognac?
maybe? does lower acid but increases stability
Completion of distillation for Cognac
must be completed by March 31 after vintage. In practice done as quickly as possible because wine remains vulnerable to microbial attack
Cognac: First distillation produces?
Brouillis. approx 27-30% abv
Cognac: Second distillation produces?
Final spirit max 72.4% abv. In practice most most reach about the max
Cognac: Heads and Tails
Tetes and Secondes are redistilled either with the wine or the brouillis
Heads in Cognac
Tetes

Secondes
Charentais Still
copper, directly heated, worm tub condenser
Charentais still for first distillation
max 140hl
Charentais still for second distillation
max 30hl but can be filled with no more than 25hl
Factors impacting style and quality in Champagne
Cut points and running temp. Cognac producers aim for a slow and steady boil (perhaps to avoid burning solids)
Lees in Cognac
Martell Method vs Remy Method
Martell Method
no lees, heads and tails added to the wine
Remy Method
Some lees are kept. This increases mouth-feel and complexity. Some contend that congeners from lees contact contribute to development of rancio
Cognac Heads and Tails
some redistill the heads and tails with the wine others with the brouillis. If diverted back to the wine result is lighter spirit (higher alc. and therefore less concentration). If heads and tails go into the Brouillis, deeper and richer eau-de-vie is produced (more congeners)
Hennessey Method
Heads and Tails are split between the wine and the brouillis
Cognac Maturation
at least two years, mostly 350l barrels, Limousin (Q. Robur) is more open grained, wood from Troncais (Q. Sessiliflora) is more aromatic
Barrel Rotation Cognac
new make spirit usually into new barrels for 6 months
