For my sins I had a singular EFP share from way back (it was a Christmas present!) and mostly considered it as a discount scheme. Reduced the price of a pint in their bars from eye-wateringly expensive to merely very expensive (20% discount at one point!) and the free delivery and access to some of their more experimental beers came in handy on a few Christmases.
The first sign of them going downhill was when they started messing around with the recipe for Punk IPA (reducing it from 5.6% to 5.4%). James Watt turning out to be a grade-A twat didn't help matters and finally the way they treated their staff with the recent closure of their bars was truly awful.
They did make some decent beers before the enshittification, ironically the Aldi 'anti-establishment IPA' is closer to the original Punk IPA than the dishwasher they've been peddling to supermarkets for the last decade!
