There are a couple of things at Aldi that I haven't found anywhere else
The coffee from Colombia has a citrus flavour that I wouldn't have thought I'd like, but has quickly become my go-to for a full-strength hit.I brew for my coffee for up to two minutes using an Aeropress and the water is around 80°C.
The Honduras coffee at Aldi is also good, but the pronounced flavour is better for weaker brews (using about half as much).
Another treat is the chocolate with coconut.
Normally I find the sugary flavour of white chocolate too rich, but it is incredibly moreish with the roasted coconut.
I'd like to say that both the coffee and chocolate are sometimes treats, but I've been indulging myself a bit.
