Hey bigdavem69,
Here are, in my opinion, the 4 most common mistakes of new brewers and how to avoid them. Hope this helps!
Mistake #1 Do not underestimate the importance of sanitation! Sanitation is arguably the most important step in brewing a batch of beer. Bacteria can and will ruin beer. Unfortunately, many new brewers do not take the time to learn about proper sanitation. More importantly, they do not take the time to practice proper sanitation procedures. Invest in a good sanitizer like Star San. Follow the sanitation instructions and on your sanitizer bottle.
Mistake #2 Pay attention to temperature! This is necessary during both brewing and fermentation. Maintaining the correct temperature is vital to achieving a good result, which is great beer. When brewing, follow the temperature guidelines on your beer kit instructions. During fermentation, follow the recommended temperature for the yeast strain selected for the brew.
Mistake #3 Yeast! Use good quality yeast, and use enough for a good fermentation. DO NOT USE CHEAP OR OLD YEAST. Yeast is extremely important in achieving a great tasting beer. Check your beer kit to ensure it contains a reputable brand of yeast. As a warning, some beer kits come with a small 2.0 gram or 5.0 gram packet of generic dry yeast taped to the lid of the malt extract cans. DO NOT USE THIS YEAST. Instead, invest several dollars to purchase additional yeast, which will replace the cheap stuff. Several of the more reputable yeast companies are Wyeast, White Labs, Fermentis and Danstar. Any of the aforementioned would be a fine choice for yeast.
Mistake #4 Impatience has killed batches of beer! Take your time and read the instructions on your beer kit. Get some affordable, yet quality equipment, and find a good pre-packaged ingredient kit. Take your time brewing, and let the beer completely finish fermenting before bottling. Relax and enjoy the process and you will be brewing great beer in no time at all.
Hope that helped!
