I brewed a Scottish ale and took a small portion of the wort and boiled it. The idea was to carmelize the wort but if you overdo it then a rubbery taste can result. If I recall correctly this is equivalent to attempting a malliard reaction but burning the subject matter.

So you may be having an issue with your wort sticking to the pot during the boil. Just a thought based on my experience.


Brewed in 2014: Rye IPA, Honey Sage Ale, Belgian Golden Strong, California Common, Bavarian Style Lager, Weizen, Coffee Stout, Gruit, Gale Ale, Isle of Skye Golden clone, Oktoberfest, Rauchbier, Alpha Male IPA & Chocolate Pepper Stout.

The inconsistent levels of chloramines or chlorine are very likely. I've read that every so often a water department may decide to flush the system with higher than normal amounts of these chemicals. And I remember one time water from the tap reeked of chlorine. I called the water department and they told me they had accidentally let too much into the system.

When I started using campden tables, I noticed my beer tasted cleaner. I don't know that I would have called the off flavor 'rubber', but there was a definite difference.

Try campden tablets or a charcoal filter and let us know how it goes!

I set out running but I take my time.
