Hot-Side Aeration

MEMBERS ONLY

Identifying that one problem, the thing responsible for the majority of brewing issues, is the dream of every brewer who knows that their beer is just one step away from greatness. And, for many brewers, hot-side aeration (HSA) becomes the boogeyman to conquer. Without smelling and tasting your beers, it is impossible for me to

Terminal Gravity Woes

Alpha amylase can be added to the fermenter to aid in attenuation, but it has limited efficacy in converting dextrins and starch into fermentables. The primary role of the endoenzyme alpha amylase in the mash is as a debranching enzyme that chops up amylose and amylopectin into pieces from the interior of these molecules. Although

Hop Creep Revisited

MEMBERS ONLY

I rarely answer similar questions in a single column, but this question pairs well with Greg Hutchinson’s question in this issue about over-carbonation and is a good follow-up to my “Hop Creep Explained” answer from January-February 2019 issue. This is kind of like beer and food pairing, but it is rather a topical pairing! OK,

Bottle-Condition Like A Champ

I am not sure how Affligem goes about bottling their beers, but your question generally applies to bottle-conditioned beers, especially those that have very little yeast sediment in the bottle.

Over-carbonation issues

This general phenomenon is loosely referred to as gushing and has numerous causes in beer. Typically there is a primary culprit in a case of gushing, but it is not unusual for a single case of gushing to be caused by multiple factors.

Feeling the Pressure

MEMBERS ONLY

Atmospheric pressure does affect beer carbonation and dispense, but the answer to this question is a little confusing depending on where the beer being dispensed was carbonated, and how carbonation is defined. It also depends on what is meant by the term “pressure.” In an attempt to write an answer that is not overly confusing,

Maximizing Malt Aroma and Character

Maximizing Honey Flavor and Aroma

Joe, thanks for the good two-part question about using brewing sugars like honey for special flavors and the question about how to bottle condition beers that may contain fermentable sugars.

Keg-Conditioning Beer
