Beer Flashcards
What is Amylase?
The enzyme that is released from germinating/malting barley that will ultimately convert carbohydrates into fermentable sugars.
The two sugar types produced are Maltose, and Dextrin.
Once this process has completed the malted barley is now called Green Malt.
What is Green Malt?
This is the result of germinated malted barley that has produced Maltose & Dextrose.
This is what is transferred into Kilns for roasting to halt the germination process.
What are the fermentable sugars of malted barley?
Maltose
.
Dextrose
What is Grist?
This is ground or cracked malted barley after roasting.
This is what gets steeped with hot water in a Mash Tun in order to derive the Wort which can then be fermented.
What is Wort?
This is the liquid that has been derived from malted grain starch being converted into to sugar.
It is the Wort that can be fermented.
What is a hopback?
A chamber the wort can be [optionally] strained to after the fermenting process where additional fresh hops are added prior to chilling and fermentation.
This process (dry-hopping?) adds the more delicate, and volitile aromas of hops to beers, and adds additional bitterness.
What is Sparging?
After Grist has been soaked in hot water to get the Wort, the Spent Grist is filtered off.
Sparging is the process some brewers will use to extract more sugar or flavor.
The spent grist is soaked with a small amount fresh water (typically about 50% of the volume of the original Wort). It must be at a lower temperature or tannin, and bitterness will be extracted from the husks.
The Sparge can then be added to the Wort and put in a brew kettle with hops.
What are the main yeast strains used in beer production?
What are their uses?
Saccharomyces Cerevisiae
- typically used in Ales
- acts at warmer temperatures
- top fermenting
Saccharomyces Pastorianus
(fka: Saccharomyces Carlsbergensis)
- typically used in Lagers
- acts at cooler temperatures
- bottom fermenting
Saccharomyces Uvarum
- typically used in Lagers
- acts at cooler temperatures
- bottom fermenting
Brettanomyces Bruxellensis & Brettanomyces Lambicus
- used in Lambics & sour ales
What yeast is used for Ales?
Saccharomyces Cerevisiae
What yeast is used for Lagers?
Saccharomyces Pastorianus
(fka: Saccharomyces Carlsbergensis)
Saccharomyces Uvarum

What is the difference between
“wet hops” & “dry hops”?
Wet hops are hops that are used immediately after the hop harvest (fall in northern hemi, and spring in southern hemi). They must be used without any processing (drying). It is basically a term of freshness…(?)
Dry hops is a practice of adding hops to beer either during, or immedeately after fermentation.
===============
Strangely enough one can use “wet hops” in the “dry hop” process.
What is a Lambic?
Ales that are spontaneously fermented over a long period of time;
aged hops provide antibacterial qualities, not bitterness
.
Main Yeast strains used:
** Brettanomyces bruxellensis
* Brettanomyces lambicus
* Saccharomyces cerevisiae
* Lactobacillus
.
* Styles of Lambic:
- Gueuze
- Mars
- Faro
- Kriek
- Framboise
- Pêche
- Muscat
- Cassis
What is Gueuze?
Name a producer.
One of the types of Lambics
.
Gueuze is a blend of one year-old and two year-old lambics, fermentation concludes in the bottle
example: Girardin “1882” Gueuze
(pic below)
==========
other types of lambics are:
Mars
-A mild lambic produced by reusing the malt from a previous lambic fermentation
Faro
-A mixture of lambic and a lighter brewed beer, Belgian candy sugar is added for sweetness
Kriek
-Lambic or Gueze with Cherries
Framboise
-Lambic or Gueze with Raspberries
Pêche
-Lambic or Gueze with Peaches
Muscat
-Lambic or Gueze with Grapes
Cassis
-Lambic or Gueze with Currants
What is Mars?
Name a producer.
One of the types of Lambics
.
Mars is a mild lambic produced by reusing the malt from a previous lambic fermentation
Example: Ommegang Biere de Mars
