Tips For a Quality Hazy IPA

MEMBERS ONLY

Welcome back to the world of homebrewing after your quarter-century hiatus! Not sure where you are in the process of brewing your current batch of New England IPA and hope this answer helps clear up a few things in your quest for unclarity. My basic advice is to give your beer a few days in

Trying to Gauge the Speed of Oxidation

This is a terrific question and is well suited for a terrifically short answer. Beer oxidation can occur shockingly fast, especially if a beer is the sort to easily show off oxidized


Measuring IBUs: Part science, practice, and opinion

MEMBERS ONLY

My view about how international bittering units or IBUs are used by the modern brewer is a blend of science, practice, and opinion. The science behind the IBU is something I have covered many times in past columns, so I will be brief. The original IBU method, and one that is still used by many

Tastes Great, Less Filling? Crafting low-carb beers

MEMBERS ONLY

The keys to clearly understanding this topic are knowing about the types of starch present in a brewery mash and how malt enzymes act upon these large carbohydrates, appreciating how exogenous enzymes can be used to step beyond the boundaries of malt enzymes alone, and considering alternative ingredients that leave little to no residual carbohydrates

On the surface, this question looks like a no-brainer. Of course the enzymes in the mash were deficient, right? 55% enzyme-free adjunct, longer than normal mash at a moderate temperature perfect for producing highly fermentable wort. And the distiller even cooked the flaked corn just to be sure that the corn starch was gelatinized before

If fermentation is truly complete, what you are seeing in your airlock is most likely the signs of carbon dioxide in the beer equilibrating with the environmental conditions of temperature and pressure. While it may seem that freshly fermented beer should already be in equilibrium with the environment, it’s probably not because carbon dioxide is

Brewing Water Tweaks

Grain bill, grist ratio (mash thickness), and salt additions all affect mash pH.

Curing Sparging Woes

The likely culprit to this problem, assuming that you have been using the same basic recipe over the last 7–8 years, is beta-glucan from the flaked oats. I am betting on this ingredient because the problem you describe is typical for how high-molecular weight beta-glucan gums associated with certain grains, most notably unmalted oats, rye,
