Bad Tastes...

I've been running into a few issues with an off flavor in my beer.  It has a terrible medicine taste and is really astringent.  Almost like a box of band aids.  This has been the downfall of many of my past few brews.  Last year I made an Oktoberfest that had this flavor.  My last two Pilsners have had this flavor and I brewed a copper ale that I am going to have to throw out as well.  Needless to say, throwing away beer makes me a sad homebrewer.

I believe this flavor is coming from the chlorine in my water.  With every beer I make I have used some amount of tap water.  I typically boil the water and add metabisulfite to break up the chloramine as well.  I thought this was getting rid of any chlorine, but I think I'm wrong.

I have been focusing on the water chemistry of my mash water and using Reverse Osmosis water with CaSO4 (gypsum)  and CaCL2 (Calcium Chloride).   I've been trying to his a 5.50 PH on my mash.  I will then use tap water or a combination of RO and tap to sparge my grains.  This is probably where the chlorine is introduced.

There maybe a few more factors going into is such as fermentation temperature or even the crush of my grains, but I'm sure it has to be the chlorine in the water.

Today I am going to make an Oktoberfest, I know it's really late in the year, and use only RO with treatment.  This should give me a chance to see if it is chlorine or if it is a different issues in my brewing process.  I want to eventually filter all my brew water, but this is be best way to insure I have no chlorine in my water.  Wish me luck.
