How Did That Mould End Up in Your Beer?

By December 5, 2016Blog

For most homebrewers, the alchemy of coming up with something brand new is part of the fun. Sometimes the results are delicious, and sometimes they’re… not.

However, there are occasions where it’s pretty clear that something has gone terribly wrong with a batch of beer. A mouldy tasting beer is one example of an unpleasant brewing surprise. If you’re wondering why bad things happen to good beer, we have some ideas.

Start with Your Ingredients

Mould generally grows in organic materials. If you’re using dried ingredients, especially if they have been sitting around in a kit for a while, there’s a chance mould was able to grow. To prevent this problem in the future, start with fresh beer ingredients and take care to store your ingredients in a cool, dry place.

Review Sanitation Procedures

We’ve said it before, and we’ll say it again: contamination is the enemy of home brew. Sometimes, mouldy beer is the result of improper cleaning of your brewing equipment after the last batch of beer. Sanitation is a tedious part of the beer-making process, but it’s also arguably one of the most important.

Check the Lines

When was the last time you had a good look at your siphoning tubes and bottling equipment? If you can’t remember, now is the perfect time to go take a good, close a look. Prepared to be amazed, but not in a good way. These pieces of equipment are often forgotten about in the clean-up process, leaving them vulnerable to all sorts of funky stuff.

Can Mouldy Beer Be Saved?

Some people are of the mind that if mould appears on the surface of the beer in the fermentation process, you can scoop it off and carry on with your day. Think of it kind of like cutting the ends off an old brick of cheese. We believe that you should hold yourself to a slightly higher standard. Even if, miraculously, the taste of the beer isn’t adversely affected, you will always know it was there. Gross! You should probably throw out that cheese too.
