Wow! That's so incredibly disappointing. Yes I did buy and use the pH strips. And AFAIK I've changed something for each new brew to try to isolate the problem (except for one time, where I merely took extra care in all my measurements). Pat's posts were the ones I took most seriously. More recently,...

I haven't re-read all the previous recommendations, are any of those still outstanding? Other than that, maybe water chemistry :scratch: I think I've explored every avenue (as much as my equipment will allow me), except water chemistry. My local (Sydney) water is soft, low in calcium. I've read an ...

I'm really sorry this is dragging on so long :cry: Another brew day has been done (see attached BIABacus sheet) Once again I undershot my GIB (1.032, but expecting 1.036/1) and of course that means I undershot my GAW. I took a proper pH measurement (fifteen minutes into the mash) and it was ~5.6 (ho...

Did you do any headspace measurments to compare? At which stage? The only time I did a headspace measurement was at the initial TWN (with cold water) in kettle stage, where I measured height and then measured headspace to double check (using a stainless ruler). All the rest up to and including KFL ...

So ESB5 just put into no-chill cube (it weighs in at 8.4kg filled with hot wort. Remembering from previous posts that my empty cube weighs "nothing" and that this measurement is probably flawed). I got the closest/best GIB yet of 1.032 (expecting 1.033). This may have been because I did a more exten...

(FYI I also ferment directly in the no-chill cube). I did go through the weighing on bathroom scales thing (but my bathroom scales measure all my empty containers as 0, so I'm expecting it's not the best of measurements). For what it's worth, just now I weighed the latest batch in its fermenter at "...

I think the point is that people have to join/sign up, read the site rules, make an introductory forum post and then get approved by admin before gaining access the BIABacus. That's what I did and found it all quite straight-forward. Reading the site rules etc actually leads you to where the file is...

PS - appreciate everyone's input. Sorry this has dragged out so long. I've just purchased a Grainfather (which might arrive in time for my next brew). I guess that means I won't need to BIAB, but I'd like to understand all these brewing issues before I move on. I think it's very important that I inc...

Ben, it's important that you act on any advice already given. For example... Maybe get some pH strips for the next brew and remember to measure the KFL and VIF as these are the best volume figures of all. The same results are getting posted but no procedural change has occurred such as checking pH ...

If the last result was typical I wouldn't be particularly worried, but it comes off the back of worse results in terms of low efficiencies. However I just want to point out again that this time I kept boiling the wort down (beyond 90 mins) till I reached close to my predicted VFO height. If I'd done...

Alright! So I just brewed another batch (another ESB - version 4) and my numbers were the closest they've ever been. I also made sure of every measurement. One major thing to note is that I let the boil run a little longer (ended up a 95 minute boil) because my volume was still 2cms too high when I ...

Is your pot tall and narrow or wide and short? If you reverse your current kettle diameter and heights, this would explain everything. Pot definitely more wide and short rather than tall and narrow. I measured pot again and the exact height is 25.5cm (rather than 25cm). Diameter definitely 30.7cm (...

Hop freshness

It's currently Craft Beer Week where I am in Sydney, AUS. A few nights a go I went to an event/talk about hop freshness. We were given a test: the same beer (a BrewCult "Hop Zone" IPA ) at 1 week old, 5 weeks old and 60 weeks old (we were not told which was which until we guessed the order of freshn...

So the latest ... good news and bad here: GIB (estimated) = 1.033 GIB (actual) = 1.030 Very happy with that. Not as happy with this: GAW (estimated) = 1.050 GAW (actual) = 1.042 I forgot to measure KFL or VIF (and have now squeezed the air out of my no-chill cube), but they're not going to alter my ...

The funny thing is, I am aware of how hop flavours & aromas can fade over time. It's currently Craft Beer Week where I am in Sydney, AUS. A few nights a go I went to an event about hop freshness. We were given a test: the same beer at 1 week old, 5 weeks old and 60 weeks old (we were not told which...

Oh and speaking of memories, my German relative told the Beck's tour guide that I was into home brewing, so they gave me a little test; they gave me a few beers to try and asked me to describe. One of them tasted horrible and I described it as "dishwater". They weren't particularly happy, but I cert...

Did a tour of Becks brewery whilst there, and must say at source, their local lager (not exported) is the best I have tasted. It is called Haake Beck, and uses more hops than their standard Beck's export (all Hallertau apparently). I did the tour (circa 2001) and absolutely loved Haake Beck Kräusen...

I've just bought a portable 2000W induction cooktop and read through this thread and many others on same topic. I'm yet to use it (until now I've been using the glass/ceramic radiant stovetop in my kitchen). Will be using a 19L kettle. So here are some observations, questions and maybe some answers ...

Actually, I'd say kettle volumes have been WRONG using the ruler until now, but only because: I was not measuring based on the actual kettle volume. Silly me, I used a measuring jug to put what I assumed was 12L of water into the kettle. I measured that amount with a ruler and used that to calculate...
