Dropped again to $149. Here is the CCC watch if anyone is interested, just enter your email and desired alert pricing. AFAIK it has never been lower than this. Mine should be arriving soon.

Kentucky Vintage has been growing on me as of late. I think it was around $35 and it plays well with a cube. The first time I had it after opening the bottle it didn't trip the trigger, but the last few times it has been quite good. I can probably find better at that price point, but it is a nice change of pace.

I picked up a can of Old Tankard and it really did not trip my trigger. It was quite malty with a decent bitterness, but nothing to write home about and it landed decidedly on the boring square. At $2 a can that would be $12 for a sixer and I'm not going to pay that for this beer. Of course if I see it on draft I'll try that to see the difference, but for me the can is a pass.

One is homebrew competitions (BJCP), the other is professional. If you are not going to enter a competition brew whatever suits your fancy.

Sounds like a scheme from BMC leading to a negative ad campaign against craft brews to me.

I got an anova circulator last year when they were doing their great sell off of the previous model and I love the damn thing. It's much better and more reliable than anything I could cobble together on my own.

What in particular are you looking for? I can say right now - get one and grab both the chef steps and anova apps for the phones because they give you a ton of guidance.

I was trying to snag one of these on Amazon Prime day they had the bluetooth model marked to $143 and I had a (nonworking) code to save $30. After that fiasco Amazon credited my account $30, but of course the Anova is back up to $180. I guess I'll just watch it and if it drops again snag it.

We have a brewery in NC where a business wanted to give beer to it's employees and so they setup a homebrew system in a room and thought they were good to go. The ABC said no and required them to file all the Federal and State paperwork. They are now the only brewery in the state which sells no beer, takes in no sales tax, and brews beer which is not distributed. They even were required to get a server to serve the beer instead of the self serve kegorator they began with.

If you want to sell beer go ahead and get a dedicated space for it and make your life easier. The ideal space would be one that could grow into your future brewery and taproom IMO.

I would have thought they might decrease, but after googling as suggested actually came up with this post from 2011
which discusses this research paper

For discussion here is the post linked above. Seems a bit aggressive on the decrease, but also notes the numbers are not precise. I'd credit the author of the post if I knew who mdma from Norway was.


Paraphrasing from Fundamentals of Beer and Hop Chemistry (text below), 2/3 of the hop bitterness in wort has a half-life in excess of 5 years, and the remaining 1/3 as a half-life of 1 year. From that, I've made a table showing the amount remaining over time. The total column shows the percentage of bitterness compared to the total at the start:

months  cis-    trans-  total
0   68.00%  32.00%  100.00%
3   65.68%  26.91%  92.59%
6   63.45%  22.63%  86.07%
9   61.29%  19.03%  80.31%
12  59.20%  16.00%  75.20%
15  57.18%  13.45%  70.64%
18  55.23%  11.31%  66.55%
21  53.35%  9.51%   62.87%
24  51.53%  8.00%   59.53%
30  48.08%  5.66%   53.74%
36  44.86%  4.00%   48.86%
48  39.06%  2.00%   41.06%
60  34.00%  1.00%   35.00%

So, if you leave a beer for 1 year, it's IBUs will have decreased to 75% of its original value. For example, an 80 IBU beer will have 60 IBUs after 1 year.

Here's the relevant part of the text:

The ratio of the isohumulones depends on the reaction conditions. In the wort medium it is normally 68:32 in favour of the cis-compounds. However, the cis-compounds are much more stable (half-life >> 5 years) than the trans-isomers (half-life of ca. 1 year) during the course of time. This affects, obviously, the cis:trans ratio and has significant consequences with respect to taste and flavour stability.

Of course, other variables do come into play, so these figures can't be taken as exact, But then, as we all know, that's how it is with brewing. Our malt isn't exactly the color on the label (usually a range of values), and hops aren't the bitterness on the pack since they degrade from the get go. So, although not exact, these figures should offer a good estimate.
