Maillard Reactions
Digital and Plus Members OnlyBeer contains hundreds of different compounds that interact with our human senses to create the appearance, mouthfeel, aromas and flavors that we experience and enjoy. The compounds that are contained within beer are either derived directly from the raw materials used to produce the beer, or are the result of the malting and brewing process
Homebrewing Oak Alternatives
Digital and Plus Members OnlyBack in the 1980s and 1990s brewers would often ask whether beers that spent a long time in oak casks, such as IPAs, would have an oak flavor. I would reply (accurately) that they did not, largely because the casks were treated before use, and were used over and over again. Indeed, they were often

Buffers and Brewing
FREEWhat is a buffer and why should advanced homebrewers learn about them? Put on your chemistry cap and sit back while we attempt to take the bafflement out of buffers.
Yeast Pitching Rates
Digital and Plus Members OnlyYeast do not want to make beer. They want to grow. The yeast do not care what kind of beer you want to make. They simply take stock of the food resources, and environment, and set out to grow as much as they can before the resources run out. To grow, yeast cells need oxygen
Understanding the Science behind Beer Foam
FREEBeer foam: It’s more than just a layer at the top of your glass, it’s a complex matrix of air and chemistry that is highly dependent upon the brewing process. Explore the science of the suds with John Palmer.
