Default First AG- some thoughts so far

Started my first AG tonight. Made my equipment, and have other posts on it, suffice it to say I have a rect. cooler MLT w/ a braided stainless manifold.

Strike temp for water was 168*F-had trouble hitting the correct mash temp, but I think that my thermometers are wrong, and I overestimated the temp of the grain when calculating the strike temp. To be sure, I went a little higher on the sparge. I also added another gallon to the mash at the beginning at a higher temp to bring it up a little, and decreased the sparge by the same. Just vorlaufed and drained the first runnings. The MLT drains nice-very happy so far. The sparge is resting right now, and I am going to drain it in5 minutes and start my boil.

All right! Way to go! Yeah I had problems getting the strike temp right the first time. The last 3 has been great though. Seems you need one time to get it right you know..... Though my last AG I used a completely different method all together. Decoction. One thing that really mattered is putting very hot water in the tun first and letting it get nice and hot so the temp does not drop when you add the grain.

Yeah- I used tap hot water-don't think it was enough. Also, I am now realizing that my evaporation rate is higher than estimated. My volume might be a little short. I am thinking of accelerating my hop schedule to get what I need-IBUs might be a little off, but its that or less volume.

Definitely need to do a post mortem on this one tomorrow. Still in my boil-~15 left

I had a little trouble hitting my mash temp right too on my AG. I preheated the cooler with 170*F water, only about a gallon or so. Closed the lid and sloshed it around, then let it sit for a few minutes before draining it. Added the grain, added the strike water, and was about 5 degrees under, so I had to add more hot water. Then the temp dropped about 5 or 6 degrees over the next 45 minutes.

I gotta take better notes next time.

Well if you are come as short as I did....



In retropects I should have added water. It was 70 points and would have tasted a lot better and probably be drunk by now if it was in the 50s.

I ended up adding the water to make 5 Gallons. The airlock is already starting to go at 7:50am this morning, so that is about 8hrs, which is normal for my brews. It'll be a little weak, but I think it will be ok for my trial batch. I now know that I should probably overestimate evaporation and absorption loss initially, and work back down. Also, I need a better thermometer, as both of mine conspired against me.

All in all, I am glad that I went AG.

Sweet! I just started this morning. I have my MLT preheat water on and my 13.75 quarts of Mash In water cooking too. Time to warm up the 10 gallon Igloo Cooler.

Not sure what the weather is like down in Austin, but it would be a nice brew day up here in MA today. Nice and cool and dry.

Hope it goes well.

It's 68 degrees right now and cloudy, but dry. It will warm up later.

Mashed in perfect. Sitting at 153 degrees for another 70 minutes. Sparge water is heating up and kettle is waiting. Burner is outside with a full tank of propane. Time to get some ice for the pre-chiller.

It's going to be a good day.
