Written for homebrewers By A. Colombo After reading the other reviews I was a little unsure if purchasing this book would apply to homebrewers. After reading this book extensively I believe that this is an excellent starting point for homebrewers who want to learn how to culture and store their own yeast.
The other reviews are correct, there are a few basic introduction chapters in the beginning but the vast majority of the book is an extensive guide on yeast culturing practices from start to finish. The author s do an excellent job explaining concepts and procedures in a clear way giving the reader a step-by-step guide, with some photographs.
The authors give examples of how commercial breweries grow up their yeast to pitchable rates, but the vast majority of this book is written for homebrewers who are working in 5 and 10 gallon batches. Everything is covered in detail, from washing and rinsing yeast harvested from a primary fermentation vessel, pitching rates, yeast starters, harvesting yeast, storing yeast, preparing slants and petri dishes and streak plating yeast cells to grow and isolate different colonies.
For those homebrewers who think that yeast culturing is way too much of a headache and prefer to purchase a new vial of yeast from the store for every batch, please give this book a chance and see how easy it is to culture and isolate your own yeast.
The author s do an excellent job of describing how complex a brewery laboratory can be, but they do an even better job of teaching the homebrewer to use the exact same techniques at home using nothing more than a pressure cooker, agar, dry malt extract and a wire inoculation loop. If you are a homebrewer who is just starting out and are using extract and partial mash recipes then perhaps yeast culturing is too large of a next step.
However, for all-grain brewers who are looking to take their recipes to the next level and begin culturing their own strains and producing strains that are unique to their recipes then this book will be an excellent starting point. The author s teach the reader how to streak yeast onto a petri dish and isolate individual colonies as well as how to select the healthiest colonies as well as how to step up these colonies to a pitchable size for a 5 gallon fermentation.
All of the other reviews for this book are fairly accurate and each has their own degree of truth, but by all means to not let the negative reviews for this book sway your decision.
It does not matter if you are a homebrewer or a full size commercial brewery, if you have considered culturing your own yeast to save money or to create new and unique yeast strains, please give this book a chance.
If you really want to understand brewing By kamel maude The information in this book is invaluable, whether you are just starting out as a home brewer, or have years of experience. After brewing for almost 7 years - mostly reading articles from popular brew magazines, collecting information from online forums, watching youtube videos, I would greatly urge you to pick up a copy of this book.
Whether it provides too much information or not, is up to you to determine, but even if the knowledge goes on unused, I'd imagine everyone would love to have an idea of what really goes on in brewing chemistry. A number of homebrewers have adopted the practice of transferring the beer from a fermentor at the end of fermentation and then adding a new batch of wort on top of the yeast cake. This is a bad practice. In yeast rinsing, you are using dilution of a slurry to encourage better stratification of trub and yeast, allowing you to separate the two.
In yeast washing, you are using acidification or other chemical means to reduce the number of active bacteria, while not damaging too many yeast cells. Shut windows and turn off any fans in the area, including central heating and air. Even though you have now eliminated air movement, bacteria and wild yeasts are still descending constantly. To counter this, light a flame, such as an alcohol lamp or a Bunsen burner, and work near the updraft it creates Figure 6.
This is an inexpensive and effective barrier that pushes airborne bacteria and yeast up and away from sterile cultures and media. Overall cleanliness. No or very low airflow. Minimal foot traffic, noise, and vibration. Wear appropriate clothing and keep hair back. Adequate lighting and ambient temperatures. Wipe down surfaces before starting work. Provide a microbe-free environment within the works. Any brewery, no matter how small, should run basic forced wort and forced ferment tests.
Lager yeast can ferment the carbohydrate melibiose and ale yeast cannot. Search this site. Wort high in glucose produced more estery beer Rice and corn also provide maltose but often lack nutrients needed by yeast Optimal oxygen levels for wort is ppm. Temperature control is more important to flavor than whether to use a glass carboy, stainless conical or plastic bucket Measurements in order of importance: temperature, specific gravity, pH, oxygen and carbon dioxide Through selective evolutionary pressure by brewers, brewer's yeast lost the ability to mate and form spores.
They are produced by combining and alcohol and an acid and have more flavor than each independently Higher oxygenation reduces ester levels Custer effect - Brettanomyces produces less alcohol without oxygen.
Unlike other yeast, it will produce ethanol in aerobic fermentation Brett can consume the wood sugar present in oak barrels The unsaturated fatty acids in olive oil can make up for underaerated wort. Report abuse. Page details. Page updated.
