One of the annoyances with Princess is they don't bother to list vintages for any wines, so it can make some pricing comparisons a challenge. They are probably trying to save the bother of re-printing as one vintage runs out of stock and the next is begun. One thing that ameliorates this situation is that far too many of the wines offered are grocery store level every day stuff that a particular vintage doesn't really matter much. Still, for the very expensive high-end wines, of which they carry a few, the vintage can be a very important and significant impact on pricing. I assume a more recent vintage, although one could argue with low sales volumes on these wines, they just might be older than we think.
My base reference is Total Wine because they are a large scale retailer with many locations across various states, including a store within hailing distance of Terminal 2 at Port Everglades, which is Princess' primary pier in South Florida and my typical launch point, along with thousands of others. Total doesn't carry all of the wines on the list - some would be easier found at a grocery store and others are a little more obscure. In these cases I used average retail pricing as might be found on a website like wine-searcher.com.
This updated listing is based on wine menus aboard Crown Princess as of Nov 8-13. Menus were dated June or July, 2017. I don't have anything from Vines, but do have Crown Grill and Sabatini's. Only one wine appeared on their lists that was not also on the DR main list and is identified as such.
I did not record prices for "wines by the glass", although I did make them red color in the listings. Generally, these wines are included in the AIBP or whatever you want to call it now. This spreadsheet is not the AIBP or Premium Beverage Pkg analysis - that is another thing altogether and you can find that worksheet posted here on the Princess board. Note that purchasers of the drink package can buy full bottles for 25% off the Princess price. So that may figure into your own calculations.
Princess' menu price is shown, plus total cost with the 15% gratuity added. The typical retail price is shown, plus a sales tax of 6%, plus a $15 corkage fee per bottle. Then, the net savings for each bottle is shown. In every case but XX, there is some net savings over buying from Princess. Note that for those longer trips where you would buy a case or more, you might expect to pay less at retail because of a volume purchase discount.
Note that you can change the sales tax rate in cell 1M. I used the rate for the Fort Lauderdale store. If buying elsewhere, a different rate may apply.
Some posters have asked or suggested that the attached Excel file be modified to compare or analyze against wine packages. I submit that will be difficult because there are two levels of packages and then three quantity groups in each package. Also, it is regularly reported on CC that the packages are not offered nor available on all cruises, particularly shorter length ones. If you download the wine file, you can play with it in Excel and sort them by price and group the wines that would qualify or fit into the Silver packages (max $29) versus the ones that would fit into the Gold packages (max $45). As for how much can be saved, the per bottle price varies depending on whether buying a 7, 10, or 12 bottle package.
If I were buying a wine package I would buy the Gold one, which can result in pricing as low as $28/bottle if buying 12 (I would personally need a longer cruise than a week or 10 days to get that much). NOTE: I have no package prices from the Crown and IDK if recent prices posted here on CC are accurate, especially since Princess has increased prices this year at least.
CHANGES SINCE 2013
Unfortunately, very little has changed for the good, and much has changed for the bad. First, almost no changes in inventory of wines offered - just a very few less than before and what has been lost are some more unusual wines. Princess has raised prices on almost 100% of the wines, with $3 seeming the most popular (most wines in the +/- $30 range). And then as I researched current retail prices, I found wine after wine either the same price as two years ago, or even less in some cases. Therefore, the situation is even more compelling to buy your own wine and pay the corkage.
Personally, I have no plans to buy the exact same wines as Princess offers to save money - many of them I would not be interested in ever buying. But I can tell if I select good value wines, I can get a nice selection on board for similar bottom line price that Princess offers up grocery store plonk.
I have included the original data in the second tab of the spreadsheet if you want to compare the data. It will make you want to pour a glass and take a good swallow.
Note that Princess has some new 1/2 bottle offerings - which makes NO SENSE to me since anyone can have a partially-consumed bottle held for free and it will be out for you the following evening - or take it back to your room and bring it back yourself. I left them in the listing for completeness, but it also makes NO SENSE to pay $15 corkage on a 1/2 btl. If we ignore the 1/2 bottle offerings, then almost 100% of the remainder can be purchased at retail and brought on board and consumed for less money than Princess charges.
I could not find reliable pricing for some of the obscure wines. Also, I am suspicious of some pricing as I may have found a price for a better level of same wine, or Princess got a lot of an unknown vintage at a good price. It's just when the Princess price is better or very close, it seems suspicious since most situations result in good savings.
Average savings (ignoring 1/2 btl lines and lines without valid retail price) is almost $15 per wine. Depending what you want to buy, implied savings could be more or less.
The Katnook Estate Shiraz remains the best value wine on the Princess list. If you like that and can drink it all the time pretty much, go for it.
For buying your own wine, I think plenty of decent value wines in the +/- $20 range which puts you in mid-30's on board with the corkage and you can beat up Princess all over - except for the Katnook.
I will be on the ISLAND on Dec 6 for a BVE and will get around and take snaps of all the wine lists there and see if there are any updates.
I hope you enjoy having the attached file and find it useful in your decisions over cruising with wine.
