Personally I would focus entirely on wines for drinking. Investing for financial returns requires significant capital outlay, professional storage in bond, a lot of patience to see any return and a huge dollop of luck.
If you buy a wine fridge, fill it with things you would like to drink and share with friends and family.
One option if you know the sort of wine styles you like, would be to Search TWS for wines that have aging potential. Click “Buy Wine” and then “Wines for laying down”…
Then when self selected mixed cases can be ordered again - buy a dozen different bottles from that list - try them - then pick up 6/12 bottle cases of your favourites and pop them in your new wine fridge to enjoy over the coming years.
The next step could to dabble in the EP campaigns regularly offered by TWS (Rhone, Burgundy, Bordeaux every year and a mix of smaller offers in between)
Most importantly of all - have fun.
