Master Brewer Certification Dietary Requirements & Special Menus 2

Question 1

A customer with celiac disease asks if your craft lager is safe to drink. What is the most accurate response?

Accepted Answer

Most conventional lagers contain gluten from barley malt and are not safe for celiacs

Answer

Conventional lagers are brewed with barley malt, which contains gluten, making them unsafe for individuals with celiac disease unless specifically certified gluten-removed or gluten-free.

Question 2

Which enzyme treatment is used to break down gluten peptides in barley-based beers to achieve gluten-removed status?

Accepted Answer

Prolyl endopeptidase (Brewers Clarex)

Answer

Prolyl endopeptidase, sold commercially as Brewers Clarex, cleaves the proline-containing peptide bonds in hordein (barley gluten), reducing gluten content to below 20 ppm.

Question 3

A vegan customer is concerned about beer fining agents. Which traditional fining agent is derived from fish and should be disclosed?

Accepted Answer

Isinglass

Answer

Isinglass is derived from the dried swim bladders of fish and is a common fining agent used to clarify beer, making it unsuitable for vegans.

Question 4

What is the maximum gluten threshold (in ppm) set by the FDA for a product to be labeled 'gluten-free' in the United States?

Accepted Answer

20 ppm

Answer

The FDA requires that foods labeled 'gluten-free' contain less than 20 parts per million (ppm) of gluten, the threshold considered safe for most people with celiac disease.

Question 5

A diabetic customer asks about low-carbohydrate beer options. Which brewing approach most effectively reduces residual carbohydrates in finished beer?

Accepted Answer

Adding exogenous amyloglucosidase (glucoamylase) to convert dextrins into fermentable sugars

Answer

Adding exogenous amyloglucosidase (glucoamylase) breaks down normally unfermentable dextrins into fermentable glucose, allowing yeast to convert them to alcohol and CO2, significantly reducing residual carbohydrate content.
