Q

What are some factors that would impact the character when growing hops?

A

The same hop variety can be grown successfully in different conditions. Factors that will influence the aroma and character;
-location, soil, slope, sunlight, temperature, and rainfall.

Q

What is important to consider about Hop essential oils?

A

They are highly volatile and will vaporise when added to the boil.

When added early (to the boil) they will add little aroma character.

When at the end or after (the boil) they will add much more aroma character.

Q

What are we referring to with Isomerisation during the boil?

A

Isomerization in the boil is when Alpha acids are converted to iso-alpha acids which will contribute bitterness to the final beer.

Q

Where do Alpha acids come from?

A

They come from the Lupulin gland in the hop cone

29
Q

How do we measure bitterness?

A

Bitterness is measured in IBUs (international bitterness units)
Beer is typically in a range of 1-100 IBUs

30
Q

What is an important consideration after harvesting Hop Cones?

A

Hop cones are dried to avoid rotting and to minimize the vaporization (loss) of Essential oils

31
Q

How are hop cones typically stored after harvest?

A

-Whole hops compressed and baled
-Milled and pressed into pellets
-As hop extracts

They are always kept in oxygen-free packs and refrigerated.

32
Q

Why were hops originally used in brewing?

A

Hops were originally used for antibacterial properties.

33
Q

What is the prize component that hops bring to brewing beer?

A

Hops are prized for the bitterness and aromas they bring.

34
Q

What are four things Yeast produces when consuming sugar during fermentation?

A

-alcohol
-aroma
-carbon dioxide
-heat

35
Q

What do we call ‘adding yeast to wort’?

A

This is referred to as pitching or inoculation

36
Q

What is attenuation?

A

the amount of sugar converted to alcohol by yeast

37
Q

What will the level of attenuation influence?

A

Attenuation will influence the sweetness level of the final beer

With high attenuation, more sugars are consumed by yeast, therefore a dryer final beer

38
Q

What yeast strain is Saccharomyces Cerevisiae

A

Ale yeast

39
Q

What yeast strain is Saccharomyces Pastorianus

A

Lager yeast

40
Q

What is the typical temperature and length of time for a Lager Yeast fermentation?

A

temp - 7-15℃
for 7-14 days

41
Q

What is the typical temperature and length of time for an Ale Yeast fermentation?

A

temp 18-24℃
for 3-5 days

42
Q

Name 6 examples of special Ale Yeasts

A
  • Abbey ale yeast
  • Saison yeast
  • Witbier yeast
  • Weizen yeast
  • British ale yeast
  • American ale yeast
43
Q

Describe the character of Abbey Ale yeast

A

Distinctive fruity aromas (banana, apple, pear, or plum) from esters and spicy aromas (peppercorn or clove) from phenols

44
Q

Describe the character of Saison yeast

A

spicy aromas (white or black pepper) from phenols and fruity aromas (citrus, stone fruit, or pome) from esters

45
Q

Describe the character of Witbier yeast

A

a range of subtle fruity aromas from esters and subtle spicy phenolic notes such as clove

46
Q

Describe the character of Weizen yeast

A

Distinctive spicy notes from phenols (clove) balanced with fruity aromas (banana) from esters

  • German
47
Q

Describe the character of British ale yeast

A

Fruity aromas (apple, pear, or dried fruits) from esters.
They do not produce Phenols.

48
Q

Describe the character of American ale yeast

A

Typical produce low levels of esters and phenols.
They tend to contribute either subtle fruity aromas or no perceptible aroma to the final beer.

49
Q

How many strains of lager yeast are there?

A

There are around 150 strains.

50
Q

What is the German word meaning “to store”

A

Lagern means to store in German.

Lagers traditionally have a long cool maturation, known as Lagering.

See the connection? 😏

51
Q

What is Brett?

A

Brett, short for Brettanomyces, is a yeast.

It can ferment more complex sugars in the wort but tends to ferment these slowly.

52
Q

What character does Brett bring to the final beer?

A

Complex aromas.

Fruity esters like tropical fruit (ripe pineapple) stone fruit (peach) and farmyard notes (hay, horse blanket, earth, leather)

Creates beers with low or imperceptible sweetness.

53
Q

What bacteria is most commonly used in brewing?

A

Lactic Acid Bacteria

54
Q

What character does Lactic Acid bacteria bring to the final beer?

A

Gives acidity to the beer and aromas reminiscent of yoghurt and sour fruits

55
Q

What character does Acetic Acid bring to the final beer?

A

A vinegar-like acidity to the beer.
(Same acid used to make vinegar)

low levels add complexity / excessive levels are undesirable.

56
Q

What does the mineral composition of water affect in beer?

A

Aroma, taste, and mouthfeel

57
Q

Moderate levels of Carbonates and Bicarbonates in the water are desirable for what type of beer production?

A

Good for beers made with dark roasted malts or highly kilned malts.

-Emphasizes malt character.

58
Q

Moderate levels of sulfate ions in the water are desirable for what type of beer production?

A

It will emphasize hop bitterness in the final beer

59
Q

What location is noted for moderately high sulfate ions in the water?

A

Burton upon Trent in the UK.

Therefore, noted for its hop-driven ales.

60
Q

What locations are known for high levels of carbonates and bicarbonates in the water?

A

in London, UK, in Munich, Germany, and in Dublin, Ireland, all have high levels of carbonates and bicarbonates.

Beer styles - Porter, Munich Dunkel, and Irish Stout.

61
Q

Why are grains important in brewing?

A

A sugar source is needed to convert it into alcohol.
Malt (malted grains) provides the sugar.

62
Q

What important components does a barley grain provide for brewing?

A
  • Starch
    to be converted to sugar
  • Enzymes
    to do the conversion
  • Proteins
    nutrients of the yeast
  • polyphenols
    involved in foam creation
63
Q

What are 3 parts of the barley grain?

A
  • Embryo
  • Husk
  • Endosperm
64
Q

What are the enzymes in the Barley Grain?

A

They are naturally occurring catalysts in the grain responsible for the conversion of starch into sugar.

(Catalysts help reactions take place without being changed or used up in the reaction)

65
Q

What 3 things does Malted wheat bring to the final beer?

A
  • Smooth texture
  • Head retention (foam stand)
  • Haziness
66
Q

What 3 things does Malted wheat bring to the final beer?

A
  • Smooth texture
  • Head retention (foam stand)
  • Haziness
67
Q

Define Adjunct

A

A non-malt source of fermentable sugar

68
Q

When a brewery decides on the grain bill, what are three considerstions for the combination?

A

-enzymatic power
-aroma character
-colour

69
Q

What does lactose do as an ingredient for beer production

A

It is an unfermentable sugar (for regular ale or lager yeast) so it will contribute residual sugar to final beer.
