Hello All,
This is my first post. I have just got started learning the BS program. I am mostly an extract brewer with 3 partial mashes under my belt. Almost all the kits are from either Northern Brewer or Midwest Brewing. I only assembled one recipe myself, a Midas Touch clone which was a partial mash. I currently do not have the traditional equipment to start all grain, that is the mash tun and such. The BIAB seems like a go for me! I do have a nice Polarware 10 gallon pot with spigot and the ability to screw in a thermometer. I unfortunately only have an electric range right now.
So first order of business, can I do BIAB?
First, I wanted to see how long and if I can boil 8 gallons of water, as this is the approximate amount needed for boil volume (it is actually a little more, but 8 is an easy number). I calibrate my stick with marks so that I can take readings along the boil.
I start the boil. On my range with lid on, I can boil the 8 gallons of water in approximately 1-1/2 hours with the lid on. The boil is not an extreme rolling boil, but the temperature is 212 degrees F.
Also will my bag be enough to hold 12-15 pounds of grain, (wet, I don't know the weight)? I have a large straining bag fine mesh 18-3/4" x 19" from Northern Brewer.
Next question, why is my boil off rate different from http://sigginet.info/brewing/tools/equipment-profile-helper?
Setting up my equipment profile boil off rate:
I start out by making my equipment profile. I used the two links as inspiration:

However, from experience with my setup, it just didn't seem the boil off rate was correct. My Pot is 14" in diameter and 16" high. From memory, it always seems like my boil off was 1/2 gallon for a 60 minute boil. So I was surprised when I plug into the profile helper that it said it is 1.12 gal/h.
I went ahead and took measurements of water boiling and here is what I got:
After 60 minutes, take a volume reading, volume is 7 -1/4 gallons (rate works out to be 0.75 gal/h).
After 90 minutes, take a volume reading, volume is 6.875 gallons (rate works out to be 0.75 gal/h).
Lets do a 120minute boil, take volume reading, volume is 6-1/2 gallons (rate works out to be 0.75 gal/h).
So it would seem that my rate should be 0.75 and not 1.12? I don't quite understand why my rate is so low compared to the predicted value. Is it because I only used water to test?
Thanks for any input you may have.
