    Basket Case

    That's an outrageous amount of residual alkalinity, which, if unchecked, will produce a very high mash pH. And it would be hard to counter it with acid and remain below the taste threshold. This could easily be responsible for your lower efficiency. I'd be surprised if it tastes good...

    Learning small scale biab

    Doug will give a solidly science-based answer to that question, but think of it this way: If you take a bath in a whirlpool tub and turn on the jets to recirculate the water, at some point all the dirt that's going to come off readily will be in the water, which just continues to move through...

    eBIAB scorching

    Any protein in that mash trub constitutes solids that are not going back in and benefiting your finished beer. If carried to the boil, protein would precipitate into hot break material. I'd reckon that the muck is primarily starches and grain solids. You are depicting exactly why I personally...

    What BIAB brewing actually is (Mythbusting for traditionalists)

    I pumped the wort out of my BIAB mash tun today into another kettle before pulling the basket. After the wort dropped below the level of the ball valve and pump, I lifted the basket and let it drain into a bucket. The wort under the basket was close to a gallon in volume. I poured it over a...

    BIAB vs 3 vessel

    There are so many threads on this general topic, or which touch on it, since it's so perennially controversial (even though it's really not :)). Here's a couple recent ones to get you started: What BIAB brewing actually is (Mythbusting for traditionalists) Has anyone ever switched from 3...

    ^Of course that would work. And it's a good way to use a spare kettle!

    Two mashes, one boil?

    I have a feeling it's to counteract what is likely to be lower efficiency with a large grain bill. It relies on the long boil to concentrate the wort and ensure a higher OG. The other stuff, perhaps not so much. Anyway, sounds like fun! Good luck on the brew day.

    Two mashes, one boil?

    I can't see a reason why this 50/50 approach won't work. But it does beg the question, why a three hour boil? Because that's the main reason for having so much water to begin with.

    Anything wrong with not adding water salts using RO water in a Cascadian Dark Ale?

    If it were me I would add CaCl and gypsum in roughly equal amounts to achieve a minimum of 50 ppm Ca. And then I would add baking soda to raise predicted mash pH to 5.4.

    What BIAB brewing actually is (Mythbusting for traditionalists)

    @Bobby_M it definitely requires recirculation, which I would ideally prefer to perform during the entire mash. At the very least, I would recirculate after mashout for a few minutes. And if that wasn't possible (i.e. no pump), I would vorlauf extensively until the wort was visibly clear. You...

    What BIAB brewing actually is (Mythbusting for traditionalists)

    The main negative about 3 vessels is really the physical space required, plus the extra tubing and pumps. All the third vessel (HLT) does is heat up water. It doesn't even need to be cleaned. So we're pretty much always talking about a 2 vs. 1 vessel cleaning situation. I like 2 vessels...

    What BIAB brewing actually is (Mythbusting for traditionalists)

    Ah, but my point is being misconstrued. Obviously the grain and hops define the recipe which defines the general style, and therefore outcome of the product. But the brewer makes wort, and yeast make beer. You can kcuf up your beer much more easily in the fermenter. It is far less easy to...

    Beer is really made in the fermenter, anyway. 🤷‍♂️

    What BIAB brewing actually is (Mythbusting for traditionalists)

    @ThenFalcon, it's a 4 gallon stainless pail. I installed an SS BrewTech rotating dip tube and run an Anvil pump. Temp "control" (kinda sorta) is provided by an Avantco induction burner, but it's not precise obviously. Inside the pail is a basket with a handle and a Wilser bag that fits inside...

    What BIAB brewing actually is (Mythbusting for traditionalists)

    What I want is a system like Bobby's that's able to brew batch sizes below 2.5 gallons in size. :) I know that's counter to the standard "bigger is better" mantra, but it's something I like to do. I bought a 10L Braumeister because it's perfect for 2.5 gallons, but the BM lacks the ability to...

    BIAB newbie with low OG

    A typical boil-off rate with a keggle (I assume that's what you mean by keg?) is 1 to 1.5 gallons per hour. Check out the spreadsheet on this BIAB Tools page to see how the volume variables interact. Check out some other software, like the recipe builder on BrewersFriend.com, to see how to...

    BIAB newbie with low OG

    Well, you may not wish to count the volume of wort that contained sediment, but unfortunately the recipe does. :) That extra volume means you either boiled off less wort than expected, or you simply started with too much water, which I think is the case here. You've listed 9.25 lbs of malt...

    BIAB newbie with low OG

    A relatively fine grind helps maximize BIAB efficiency. If you had the grains milled at a homebrew shop, they are notorious for milling in a "middle of the road" sort of way. That could be one factor. The next factor is simply the method by which you are predicting those OG values. How much...

    Best BIAB types to start with?

    Read the older, web-based version of How to Brew while you wait for the book. Don't focus so much on the equipment, because that changes, and the book doesn't cover newer electric brewing systems. Focus on the basics of how the craft is practiced. In fact, the equipment section is useful...
