19
Q

rotary fermenters

A

fermentation takes place in a horizontal tank

-it keeps the juice in constant contact with skin

20
Q

rack and return

A
  • fermentating juice is drained and put into another vessel, leaving cap behind
  • juice is pumped back over the cap
  • done once or twice very extractive and heat dissipating
21
Q

pump over

A

drawing off fermenting juice from bottom of vat and pumping it up on the top
-dissipate heat and oxygenate juice

22
Q

punching down

A

1) traditionally done by hand with paddles at the end of sticks
- a person could become CO2 sick

2) mechanical paddles
- care to not over work the cap
- fermentation w/ tannin are more easily extracted

  • not to exceed 35C kill yeast zone
  • control color, flavor, tannin by control temp
  • wine maker may choose to reduce temp at end of fermentation to control tannin
25
Q

cold maceration or cold soaking

A

once fruit has been crushed

  • period of time skin is left in juice at a low temp
  • before fermentation
  • extract flavor and color
  • tannin are more soluble in alcoholic solution
26
Q

the vast majority of red wine making is de-stemmed and crushed. what techniques are limited to this?

A

1) pre fermentation - cold maceration
2) temperature control 20-32 / 35 kill
3) cap management - extraction control

27
Q

what is the key to red wine making to make it successful

A

1) extraction of color
2) tannin

  • more considerations during & after fermentation
  • pressing happens after fermentation
  • MLF standard practice no stylistic choice
28
Q

semi carbonic maceration intails?

A

1) vat filled with whole buches
2) grapes are crushed under the weight
3) ambient yeast starts fermentation
-produce CO2 which fills tank
-remaining berries under co carbonic maceration
NO CO2

29
Q

why would a winemaker choose to ferment using semi carboinc maceration?

A

better integration of aroma from intercellular fermentation

  • retains fresh fruit character
  • some notable pinot noir is done this way
30
Q

carbonic maceration intails?

A

1) placing only whole uncrushed bunches into vats
2) vat filled with CO2
3) intracellular fermentation starts
- at 2% ABV, skins split and juice released
- generally pressure at this stage

31
Q

why would a wine maker choose to ferment using carbonic maceration?

A

method of fermentation extracts color but little tannin

-soft fruit –> kirsh, banana, bubble gum, cinnamon

32
Q

styles of whole bunch fermentation

A

1- carbonic maceration
2- semi carbonic maceration
3- whole bunches w/ crushed fruit

33
Q

whole bunches w/ crushed fruit fermentation intails?

A

1) whole bunches not covered w/ CO2
- largely submerged by crushed grape
- therefore intrcellular fermentation take place
2) whole bunches progressivly crush b/c punch down

34
Q

why would a winemaker choose to use whole bunches w/ crushed fruit as a fermentation choice?

A
  • more carbonic achieved by higher percentage of whole berries
  • technique- silkier texture and brighter fresher fruit character
35
Q

describe blending rose production

A

small quantity of red wine is added to white

  • not permented in EU except Champgne
  • some fruity inexpensive NW wine made this way
36
Q

describe short maceration rose production

A

black grapes are allowed to macerate to extract flavor and cover

  • duration–> how much color and tannin
  • free run juice is drained off and fermented in cool temp
37
Q

describe direct pressing rose production

A

black grapes are crushed and pressed in the same way as in white wine production
-extracts little color and care not to extract too much tannin

38
Q

in basic terms, how is rose made?

A

1- direct press
2 short maceration
3-blending

39
