![]() ![]() Any 'compaction' takes place at the top plate 'false bottom', and decompresses with every periodic pump rest. Bottom-up means the grain bed is constantly being floated. As improbable as that seems, I assume it is because of the bottom-up recirculation flow path of the wort during mash. My average mash efficiencies are always at least 83% or higher, pretty much independent of grain bill size, water volume and grist:water ratio. My system is an ancient, non-trendy 'mature' Braumeister all-in-one. And I have never experienced any of them. I also got a nice bump in efficiency after I started adjusting my mash ph with a couple ounces of acid malt where its needed.Ĭlick to expand.These are all very interesting descriptions of how and why all-in-ones can be less efficient. This has been working pretty well for me. 7 * 1.5 = 10.5 - 3.5 = 7 qts that I expect to run off and I want 16 so my sparge water is 9 qts but minus that extra gallon so 5 qts. Then I calculate water loss to grain as half, so 3.5 qts loss for 7 pounds. So for example if my recipe was 7 lbs of grain, then 7 * 1.5 = 10.5 / 4 = about 2.6 + 1 gallon = mash in with about 3.6 gallons. I wait for about the first gallon to run off and then I just pour sparge water in bursts over the metal plate that sits on top of the basket, much as will fit each time and wait for it to drain. I drain in into my kettle and boil on the stove. When I calculate the sparge water, I subtract that extra gallon back out. I have their pump and I recirculate the mash. So I calculate mash water at 1.5 qts per pound and add a gallon for the space under the basket. 3.5 goes into the fermenter so that I actually get 3 gallons of finished beer after all losses when all is said and done.Īs tracer bullet said, there is just about a gallon of dead space under the basket. Collect 4 gallons out of the Foundry and boil down to 3.5. it's super true and often repeated - find a good method that works for you, get a consistent efficiency, and just roll with it. I find this to be really repeatable and I know how to scale my recipes around that. ![]() Recirculate and lift / lower and you'll probably be around 70% with a good grain crush. If you're doing more session stuff you can probably stick with the basket. I've started doing this with my "bigger beers" other wise the grain bed is quite dry, or I have to add a lot of water and spend like 2 full hours boiling it back off. Of course the process can get a little harder. You still have what's underneath and ought to recirculate but even if you don't it helps a lot. It gets rid of that 30% or so around the side. There's a false bottom mentioned around here too, fits perfectly with big open spaces. Keeps what's in the basket itself from getting somewhat saturated and not pulling any more sugar out of the grain. Recirculating combined with lifting / lowering the basket a few times is a huge benefit to get all that dead space mixed in. Well it's true for all Anvils but for us it's an even larger percentage of what we are starting with. I've detailed it elsewhere, maybe here a while back, but we are almost a full gallon under the basket and yet another 30% of the water still remaining is outside of it. ![]()
