Using Water Profile for Brewing

MEMBERS ONLY

Rick, water chemistry can indeed be confusing. I think one of the reasons that the topic is so frustrating to read about is partly due to the number of different units that are used to express the concentration of ions in water. The analysis you sent from Ward Laboratories is typical of modern water lab

Pre-Boil vs. Post-Boil Water Ion Concentrations

MEMBERS ONLY

This is a really good question. Water chemistry is discussed in terms of pre-mash concentrations with minimal attention given to the concentration of ions following mashing (and boil). Perhaps the primary reason for this view is that water chemistry’s greatest influence on beer is through its effect on mash and wort pH. Malt enzymes, protein

Proper Racking Techniques

MEMBERS ONLY

Fortunately for homebrewers there are convenient ways to move beer around without ruining your homebrewed suds with the ill effects associated with oxygen. As you mention in your question, one handy method to help reduce oxygen pick-up during racking is by using carbon dioxide as a blanketing gas. While this method is handy, it does

Cask Ale Beer In A Bag

MEMBERS ONLY

The bag-in-box method has never really been common among homebrewers, but is a technique used by many pubs around the world. The reason your beer is not carbonating is that a rigid vessel is required to house the bag. This allows the beer to be pressurized above atmospheric pressure and to become carbonated. The challenge

Racking Question
