Entry is free, but you do need to book in advance and have one or more bottles of wine that meet the selection criteria ie a red wine made by Penfolds that is 15 years or older. If the ullage (wine level) is still in the neck of the bottle ie before it starts to curve out then recorking probably isn't needed unless it's a really old bottle in which case the cork may be starting to deteriorate and replacing it may be a good idea even if the level is good.
I went a couple of years ago and it was really interesting. I had three bottles checked (all passed, thankfully), and it was interesting to get the opportunity to taste (a small amount of) the wine itself before they were topped up, resealed, a certified sticker attached, and the bottle wrapped in tissue paper.
Be aware that there is a risk - if Penfolds does not pass the wine as ok, which may happen if it's that bottle of Grange you've stored on top of the fridge for the past ten years, then they will not top it up and instead it will be re-corked with a plain, unbranded cork. It would then need to be drunk/used in cooking/tossed out pretty soon. Full Ts and Cs here: https://www.penfolds.com/en-au/events/recorking-clinics/reco…. They do warn you before they open the bottle and give you the chance to back out - and that's fine if you do. Personally I'd prefer to know if the wine is ok, and if it's not then that's sad but it's just taking up space. If you have a cellar with a number of bottles, you can also always just take one and have that tested - if it's ok then you can be fairly confident that the rest of your wine is also probably ok. If however you are one of those people who have a bottle or two as an investment and never intend to drink it (https://www.danmurphys.com.au/product/DM_453666/penfolds-gra…) then you're probably better off not taking it. :-)
It would make for interesting people-watching, much like 'Antiques Roadshow'.
The excitement, trepidation, and either relief or disappointment.
