Brewing With Lactobacillus

Why does Brettanomyces get all of the attention when it isn’t even responsible for making sour beers sour? Lactobacillus can do in a week what takes Pediococcus a year! Lactobacillus needs a


Blending Sour Beers with the Solera Method

MEMBERS ONLY

Rather than blending to taste at bottling, a solera relies on mixing beers of multiple ages together during aging. When a portion is removed for packaging, the volume is replaced with younger beer. The younger beer can be unfermented, fermented, or even soured. In this way, the solera slowly evolves.

Brewer’s Yeast & Brett Fermentation Flavors

Yeast cultures have flavor. Ever tried one? An unfiltered beer with yeast in it therefore will have yeast flavor. But what about filtered beers? Yes, those beers have yeast-derived flavors too. Yeasts synthesize flavors during fermentation, and many of these flavors stay in the beer, even when the yeast is removed. Yeasts do this in

Fermentation Temperature Control

MEMBERS ONLY

Fermentation temperature is a critical brewing variable. Temperature directly influences the metabolic rate of the yeast and the rate of the biochemical reactions associated with fermentation. Fermentation temperature has a significant impact on the quality of the finished beer, so control of this variable is very important for the brewer. There are numerous ways for

Oxygenation of Wort

Availability of dissolved oxygen to yeast during the initial stage of fermentation is very important. Yeast use oxygen to build cell membrane components that are essential to replication. Unsaturated fatty acids, sterols (both found in wort) and oxygen are all necessary for yeast to rapidly reproduce during the initial stage of fermentation. Without enough available

High Gravity Fermentation

This is one of the questions that makes me scratch my head, and for more reasons than one. My first response actually has nothing at all to do with the question.

Wort Temperature During Fermentation

MEMBERS ONLY

An active fermentation does create an appreciable amount of heat energy. In small fermenters where the ambient air temperature is used for cooling, there is always an increase in fermentation temperature as the brew goes into active fermentation. Most brewers compensate for this by setting the room temperature a little cooler than the desired fermentation temperature.
