Ciphering Fruit Beers

MEMBERS ONLY

Calculating the impact a fruit addition will have on a beer’s ABV is tricky — so much so that even commercial brewers have gotten in trouble for miscalculating their influence on gravity. We take a closer look at the math required to get it right.

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

Understanding & Using Refractometer

MEMBERS ONLY

Refractometers are widely used in the wine and beer industry to track the progress of fermentation, but they are less commonly used by homebrewers. However, if used properly a refractometer can be a great tool to track specific gravity in place of, or to supplement, your hydrometer. It is used primarily in brewing beer to

Understanding Specific Gravity vs. Plato

The simple hydrometer can tell us the gravity of our wort, and therefore the amount of extract we have recovered from our ingredients, and can even be used to tell us what extract we can expect from different malts. The hydrometer can also tell us how much extract the yeast has used during fermentation, and

Brewing Strong Ales

If you ask 10 different brewers to define “strong ale,” you will likely get 11 different answers. Brewers around the world have always made bigger, stronger ales for special occasions, for blending with weaker ales or to be aged before consumption. As craft brewers have begun pushing the limits of what can be brewed and

Taking original gravity readings
