The Android system. In not allowing reversion to the previous, or the factory version, is a disaster waiting to happen. After experience with various update fails over the years, I now always dismiss the update prompts. It's criminal, that you can't stop them reminding you to update daily...

Home grown, is good for late additions. But with an unknown AA, they're dodgy to use for bittering. Not sure if 'hop cones' you mention, is the same as 'leaf hop' in UK. Here, leaf hops are readily available for Fuggles and EKG, and maybe 25% of the hop types (though you have to shop around)...

My worry, is that any remaining debris can go mouldy, even if star-san etc has sterilised its surface. And that no amount of heat, at next use, can destroy all toxins produced. So I stick with just an immersion chiller. But, with living in the Scottish Highlands. The low supply water...

Did a blackcurrant sour last year. 20L batch, 6.2%. 2kg pils malt; 2kg wheat malt; 500g sugar; 10g Northdown (11 IBU). 1pack Philly sour 1kg blackcurrants in primary, +500g boiled and cooled in secondary. Was aiming for 300g Lactose. But ended up being so sour, that I put in the whole 500g...

I never use the top plate during mash, to avoid extra weight on grain bed. As I go for a fairly thin mash, the malt is always covered with a layer of wort. Which is going to evenly spread recirculation anyway. I do use it for sparging. Can't work out why people would want to stir during mash...

A minimal stir regime, has done wonders to my BZ g4 performance. After 4 hard work brews, with lots of power stirring. With the last, a Hefeweizen, ending up with a thick layer of burnt flour on the base, and an overheat shutdown (it ended smokey and undrinkable), I ordered bags. But in the...

Not sure if this thread is about Grainfather (app) or Brewfather, or if they're the same? I've had the BZ g4 for 30 brews, and use Brewfather app. Not sure where Brewfather gets the efficiency figure from. BZ efficiency is lightly to vary, depending on various factors, especially the grain...

Agree. I made a blackcurrant sour last year, which was way too acid, even after large lactose addition to balance it. And I only like very dry ciders. It's mellowed well, after 9 months. Nice for hot days, but it's still my only beer, that I couldn't manage a second pint! From (my poor) memory...

I'm prepared to put in 5 seconds of effort, where that will prevent a 5% loss on efficiency. Eg BZ full volume mash. 6kg grain,; 1 litre/kg absorbtion ratio.

I live in Scotland, but never buy marmalade as it always seems too sweet. Instead make my own, using reduced sugar recipe. Using 'Marmade' prepared Seville Oranges. One can makes about 5lb (cutting sugar to 75% of can recipe) and now costs £2.60. For wine or beer additions, you'd be much...

Methanol, can cause irreversible bilateral blindness. Not sure of amounts needed to be a health hazard. But when making biodiesel, using about 30L of methanol per batch, I had a system that vented any methanol fumed outside. Never worried much about the methanol itself, but did wory about the...

Efficiency calculations, with corrected 4.6L deadspace. This brings efficiencies down, if deadspace water not utilised (non zero deadspace values in table). Effect of deadspace outside malt pipe, on Lauter Efficiency. Brewzilla gen4 35L with maximum 31L fill Deadspace...

Updated Brewzilla void volume calculation. The deadspace volume, from above malt pipe perforations, to 31L fill, is 4.6L Brewzilla gen4 35L Void area - outside malt pipe (mm2) 12579 Water level rise (mm /L) 14 Top of malt pipe perforations...

It was good to see your workings explained, A nice method.

Thought it might be interesting, to re do the calculations for efficiency impact of 4.3L deadspace, when using a larger grain bill of 6kg. Cant work out where doug293cz got 25L collected wort volume came from. So replaced that with calculated amount, by deducting grain absorbtion. Efficiencies...

Your earlier post on the first case, and second case: You don't say, but I assume the above was for 25L of wort collected (as in second case). How did you arrive at 25L? Ran your calculations (in Excel), to help me understand them better. 2nd column uses water densities for strike at 65°C...

I knew that my Brewzilla system body was slightly elliptical at the top (though never checked if that was a regular ellipse or not), but is fairly circular at the bottom (though the fist one I'd been sent, was elliptical here, with it's long axis in a different direction). But I don't know what...

The (possibly correct) figure is that volume increases by 61.7% of the weight of maltose, but there seems to be disagreement on whether the same figure applies to sucrose. What exactly is grain absorbtion ratio? I've often wondered, but never found any concise answer. As you point out any...

Things with a distinctive smell, like pipe tobacco, are one of the best things to take into old people's (care) homes for 'remembering days'. People who are no longer responsive to sights or sounds, can often still show they enjoy certain smells.

There's a guy in Norway, who uses spruce or pine branch tips, to make a filter bed for mashing. I often do his Rongoteus (the Norwegian god of rye) recipe, for a Rye beer.
