Re: 2011 Declarations
Are these measurements (4.05 and 4.35) of pH level, or of grams per litre? If the latter, does pH level correlate?

And does it make a difference what type of acid (tartaric / malic / citric)?

slide 19 is pretty interesting.
the perceived level of acidity can be changed with the addition of sugar.
also very interesting
http://www.chemie.fu-berlin.de/chemistr ... lu_en.html
glutamic acid (the acid component accociated with MSG) has a ph 3.22
doesn't really percieve as sour, rather it does lower the ph of a solution.

btw to your question, ph level is entirely relevant to measure the acidity of a wine.RAYC wrote:Are these measurements (4.05 and 4.35) of pH level, or of grams per litre?

the types of acid simply makes up the mixture that would potentially lower or raise pH.
Tartaric acid is the lowest of the bunch and is usually used in wine making to stabilize a wine to keep out microbial bugs.

Re: 2011 Declarations
Will have to read up!
So what kind of picture of acidity does the quote of "grams per litre" (as published for Symington 2011s) give us in the absence of also giving pH levels?

Re: 2011 Declarations
If those prices are mainstream, then they look a little ambitious (Roriz is clearly a typo)Uncorked have published their pricing on the Symington 2011
They are, roughly, last price plus RPI; but since then, the wine investment market has caught a severe cold...

I believe it gives you only the Total Acidity measured in grams per litre.RAYC wrote:Will have to read up!

I think it means in a 750ml bottle
there are say 4.3 g/l of total acids

Re: 2011 Declarations
I've never quite got my head round this one - all acids are not the same, so it must be referenced to a specific acid, or the figure won't mean much.I believe it gives you only the Total Acidity measured in grams per litre.

Whatever, I'm not really interested in acidity or sugar content, it's what it tastes like that matters...

Do any or all of these values change over time as a VP ages in bottle?

I'd be very curious to see this too,
my assumption is yes because of Adrian's response re: the Taylor Scion that due to various evaporations they were able to determine the age by just measuring the ppb of Lead.
But what about in bottle where if the bottle were properly stored there's no ullage, if the port will truly get "denser"

Good website work by the Syms and TFP, and by almost nobody else. Sigh.
No Quarles Harris. No Gould Campbell. No Martinez. No Skeffington. Is this the end of the no-terroir ports?
Any news on Noval Nacional?

Either way, enough houses declaring to call this a general declaration, which it makes it the first '1' year to be generally declared in the two centuries since the system began..

Re: 2011 Declarations
I guess 1931 had too few declaring to count as 'general' and 1991 was split 1991/2.Either way, enough houses declaring to call this a general declaration, which it makes it the first '1' year to be generally declared in the two centuries since the system began..
It is interesting looking at the number of times (or % of times) in which years ending with each digit are declared, to see if there might be any decision bias; The following is a rough count of general declarations for the last century (1901-2000, or 1900-1999, whichever you prefer) for years ending with each digit, with split declarations counted as a half - there might be argument about a few of the years as to whether they were 'general' or not, but the idea holds:
xxx0 5
xxx1 0.5
xxx2 1
xxx3 1
xxx4 2
xxx5 4
xxx6 1
xxx7 3.5
xxx8 1.5
xxx9 0
Overall therefore, it seems far more likely to declare in years ending in 5 and 0.. possible decision bias, though I'm sure the case could be argued for this being a coincidence, especially with 7 also have a decent count. Ok, so lets have a look at the 19th century instead:
xxx0 5
xxx1 2
xxx2 1
xxx3 3
xxx4 3
xxx5 2
xxx6 1
xxx7 3
xxx8 3
xxx9 0
These totals use TPF's list of declared years, as I do not know whether any of them were/were not general declarations. Again, years ending in zero are substantially ahead, though 5's do not feature so prominently. Interestingly again no years ending in 9 declared in this century either.

No immediate plans to market it though, and she hinted that the regular Noval may be late on parade.
