[Here is a wine criticism written by Susie Bayarri in 2013 about a 2008 bottle of Altos de Losada, a wine from Leon:]

altosThe cork is fantastic. Very good presentation and labelling of the bottle. The wine  color is like dark cherry, I would almost say of the color of blood. Very bright although unfiltered. The cover is d16efinitely high. The tear is very nice (at least in my glass), slow, wide, through parallel streams… but it does not dye my glass at all.

The bouquet is its best feature… it is simply voluptuous… with ripe plums as well as vanilla, some mineral tone plus a smoky hint. I cannot quite detect which wood is used… I have always loved the bouquet of this wine…

In mouth, it remains a bit closed. Next time, I will make sure I decant it (or I will use that Venturi device) but it is nonetheless excellent… the wine is truly fruity, but complex as well (nothing like grape juice). The tannins are definitely present, but tamed and assimilated (I think they will continue to mellow) and it has just a hint of acidity… Despite its alcohol content, it remains light, neither overly sweet nor heavy. The after-taste offers a pleasant bitterness… It is just delicious, an awesome wine!

O’Bayes 2015 [day #3]

vale6The third day of the meeting was a good illustration of the diversity of the themes [says a member of the scientific committee!], from “traditional” O’Bayes talks on reference priors by the father of all reference priors (!), José Bernardo, re-examinations of expected posterior priors, on properties of Bayes factors, or on new versions of the Lindley-Jeffreys paradox, to the radically different approach of Simpson et al. presented by Håvard Rue. I was obviously most interested in posterior expected priors!, with the new notion brought in by Dimitris Fouskakis, Ioannis Ntzoufras and David Draper of a lower impact of the minimal sample on the resulting prior by the trick of a lower (than one) power of the likelihood. Since this change seemed to go beyond the “minimal” in minimal sample size, I am somehow puzzled that this can be achieved, but the normal example shows this is indeed possible. The next difficulty is then in calibrating this power as I do not see any intuitive justification in a specific power. The central talk of the day was in my opinion Håvard’s as it challenged most tenets of the Objective Bayes approach, presented in a most eager tone, even though it did not generate particularly heated comments from the audience. I have already discussed here an earlier version of this paper and I keep on thinking this proposal for PC priors is a major breakthrough in the way we envision priors and their derivation. I was thus sorry to hear the paper had not been selected as a Read Paper by the Royal Statistical Society, as it would have nicely suited an open discussion, but I hope it will find another outlet that allows for a discussion! As an aside, Håvard discussed the case of a Student’s t degree of freedom as particularly challenging for prior construction, albeit I would have analysed the problem using instead a model choice perspective (on an usually continuous space of models).

montanaAs this conference day had a free evening, I took the tram with friends to the town beach and we had a fantastic [if hurried] dinner in a small bodega [away from the uninspiring beach front] called Casa Montaña, a place decorated with huge barrels, offering amazing tapas and wines, a perfect finale to my Spanish trip. Too bad we had to vacate the dinner room for the next batch of customers…
