OK, made two batches of All-Grain recently. One came out clear as a bell after much effort. Then just today I did another and it was very cloudy coming through the siphon. So here are the things that I did differently
1st clear batch
Precisely measured mash water and sparge water for temp and amount.
2nd cloudy batch
Accidentally ran the numbers for my mash schedule with '5 gallons' as the target instead of 6 gallons. So, when my brew pot was about a gallon short, I added 150* water (about 1.5 gallons) as a late sparge.
I noticed that the wort was clear as a bell when it went from mash tun to brew pot. But when it went from brew pot to fermenter, it was cloudy as hell. I am beginning to think that I didn't properly hit my hot break?
I added the wort to the brew pot about a gallon at a time as it drained from the mash tun. I didn't start the 60 minute timer for the brew until all 7 gallons was in the brew pot. Could this gradual adding of wort be part of my problem?
This time I did add 1 tsp of Irish Moss with about 10 min to go. Hopefully that will help. This batch should also sit for a good month in the fermenter and should get several weeks in the keg before it gets tapped. Hopefully that will help it clear. This is my first attempt at my Surly Furious Clone and I was sooo excited. I thought I had solved my cloudy beer issues.
On a side note, how often/well do you clean out your mash tun and brew pot. I really hit them hard when I got my clear batch, but this time I just gave them the once over. I mean, they are clean but not sparkling. I figure it all goes into a 60 min boil so I don't work it too hard. Could this be part of the issue?
