Mad Brewer/ How To Brew Testing Kit
I received my Mad Brewer Kit today on 1/9/18 Everything was packed perfectly. Very fast shipping too. I also have a new best friend, it is my hydrometer which is a must have item if you want to brew. The kit has the right stuff you need for your beer to come out with good taste and a clear brew. This kit also has a great book on ( How To Brew) By John J. Palmer. This book has everything I mean EVERYTHING! You need to know to brew great beer every time. I don’t think John J. Palmer forgot anything, It’s all there. It even has a chapter on making your own recipe, wow its a thick book. So if you are going to brew beer you better add this to your order, you’ll be glad you did!

Excellent addition to any brew kit
I purchased this kit with the deluxe brewing system, and it was an excellent addition. It made the brew process that much easier. The book is very informative, and an excellent reference text. Plus being able to measure specific gravity and ABV is an fun way to make sure fermentation is proceeding well.

Would recommend anyone to get this with their first homebrew kit. The book is great to read and to refer to when needed. The measurement tools are essential as well!

Cool kit, but imperfect
The economy test jar had a slow leak at the base, which I fixed with a dab of superglue. The three-piece thief is also a bit leaky but works fine for transferring liquid a few inches from a carboy to the test jar. I learned by reading online reviews that Biofine Clear should not be used when priming beer for bottle conditioning because it removes the necessary yeast; so I wish that was clearly stated on the kit's instructions.
