Looking into getting a solid sided basket made from Colorado Brewing Systems and I have a couple of questions for everyone:
1. What do you guys mill your grains at? According to their
website: "
Although our systems utilize a single vessel design, this is not a Brew in a bag process. Due to our constant recirculation, it is recommended that you do not mill your grains finer than an 0.45 mill gap setting." I have no idea what 0.45 mill gap setting, is that 0.45mm, 0.045", or some other measurement I am unaware of.

I used 0.039 and have never had an issue on my CBS and I normally see around 70% efficiency.

2. In addition the same
website states:
When brewing with Oats, unmalted barley, wheat or other undermodified grains it is important to do a Beta-glucan rest between 104 and 120 degrees for approximately 20 minutes to break down the enzymes. Failure to rest at this temperature will cause the undermodified grains to become gummy and may lead to a clogged screen. Do you guys do a Beta-glucan rest? If so do you find that you have to do a Beta-glucan rest all the time only or only on beers that might be "gummy"?
<Hommel> I've never had a "gummy mash" and I have done hefeweizens at 50% wheat. then again, i'm normally in the 1.5 - 2.0 qt / lb for thickness so since my mash is on the thinner side may be why i'm not seeing any issues. I don't see how the CBS setup would be any different than any other as far as stuck mashes are concerned. if you are 1.25 with 50% wheat you should use rice hulls no matter what type of system you are running

3. What do you guys find is the correct throttle of the pump so that you are not exposing the element but still getting a good recirculation? 1/2? 1/3? 1/4?
