Why Use Adjuncts? Flashcards
What are adjuncts traditionally used for in brewing?
Adjuncts were used as an additional source of extract to replace or supplement malt.
What are the primary reasons for using adjuncts today?
- Reduce raw material costs
- Extend brewhouse capacity
- Provide specific beer attributes
How do adjuncts help in reducing raw material costs?
The manufacturing process for many adjuncts is simpler and uses less water and energy.
What factors can increase the price disparity between malt and adjuncts?
- Limited availability of malting barley
- Availability of other cereals like maize, sorghum, and rice
What is the impact of adding adjuncts on brewhouse capacity?
Adjuncts enable an increase in output without significant additional equipment.
How can adjuncts facilitate an increased number of brews per day?
By reducing the amount of malt used, leading to less milling, mashing, and spent grains.
What is the effect of adjuncts on wort fermentability?
Adjuncts can increase the concentration of fermentable sugars in the wort.
What types of adjuncts can provide starch for improved fermentability?
- Grits
- Flour
- Purified starch powder
How do adjuncts influence beer flavour?
They can result in a lighter, cleaner flavour compared to beers brewed with only malted barley.
What is a common characteristic of beers brewed with adjuncts?
They tend to have a lighter palate and are less cloying than all-malt beers.
What role does wheat play in brewing?
Wheat contains high molecular weight proteins that increase palate fullness and haze.
True or False: All adjuncts dilute malt flavour.
False
What is the primary contribution to foam stability in beer?
Degradation products of high molecular weight proteins.
What is colloidal stability in beer?
It refers to how unlikely a filtered beer is to form haze over time.
How can reducing malt concentration affect beer clarity?
It can reduce the potential for haze formation due to lower proteins and polyphenols.
