I brewed an all-grain Irish Red Ale from a kit purchased from homebrewing.org (Adventures in Homebrewing) on Sunday 1/8/2017.

I Brewed in a Bag (BIAB) with my grain mashing at 152 degrees for 60 minutes in a 10 gallon igloo round cooler. I stirred the grain initially and then every 15 minutes throughout the mash process for a total of 5 times (0, 15, 30, 45, 60 minutes).

I then placed the bag in another 10 gallon round igloo cooler with a calculated volume of water at 152 degrees for 30 minutes and stirred it initially then every 10 minutes for a total of 4 times (0, 10, 20, 30 minutes).

I then combined the first runnings and the second runnings and boiled the wort for 60 minutes adding my hops intitially, at 45, and at 5 minutes. This was done in a 10 gallon brew kettle from SsBrewtech.

I cooled quickly with a clean copper immersion chiller to ~68 degrees.

I ran the wort through a plastic funnel with plastic screen into the fermenter and pitched my yeast. I areated the wort prior to and after pitching the yeast.

The beer fermented for 2 weeks in my conical fastfermenter. I emptied the trub after 6 days and the yeast after the tenth day.

I kegged the beer after 2 weeks in a cornelius keg and unintentionally over-pressurized at 30 psi for 9 days.

I also added unflavored gelatin dissolved in a cup of hot water to the keg to clarify the beer. I added the gelatin 5 days after kegging.

For the past 2 days, I have been bleeding of the excess pressure to bring the pressure to ~11-12 psi so I can drink the beer this Saturday without the beer being over-carbonated and all foam.

Last night I tasted the beer after pouring off 2 pints that contained the gelatin etc.

The beer tasted metallic....... drinkable, but not very good. The OG, FG, and ABV all came very close to what the directions indicated. Fermentation went smoothly.

I read in John Palmer's brewing book that unprotected metals can impact a metallic taste.

I did not use any metals in my brew process except good quality stainless steel which isn't suppose to give off any tastes.

I also feel I was very clean and used StarSan when needed.

This is my first all-grain brew and am a little disappointed.

Anyone have any suggestions on what I did wrong?

Thanks very much.
