So I just brewed up a beautiful category 5D Pilsner, doing a single step decoction mash.
A modified Zapap lautering device was set up for wort recirculation in the mash tun, using a food grade (FDA approved) plastic bucket, with holes drilled in a shower-head pattern. The manufacturer advised it has a working temp rating of 180 degrees.
I cut the recirculation short after I noted a faint odor of plastic. Finished up the brewing, pitched the yeast, and thought all is well.
Just now we heated up some water to 185 degrees, with this plastic bucket submerged in the water. I did detect a faint aroma of warm plastic.
Then my wife and I both tasted the water the bucket was in...you guessed it, tastes like plastic!
Will this taste show up in the finished beer? Will it be detectable now, after two days of vigorous fermenting?
While the bucket is actually made in China, the manufacturing company is M&M Industries, Chattanooga, TN.
This was my method for mashing, decades ago before we went all stainless. Never had an issue before.
What do you think, is this a 10 gallon toilet flusher?
