I’m not a Cava expert, but I really like the Pere Mata l’Origen. But, be warned, it is inexpensive Cava; and not even the top of their range. I like it because it doesn’t have Parellada; only Macabeu and Xarel•lo, so it’s more mineral. Maybe their Reserva Familiar (which has Parellada and some barrel-aged reserve wines) is more gastronomic.
I also had another cava from their range at a restaurant, Cupada Rosé which is a blend of 1/3 Parellada and 2/3 Garnacha (and even cheaper than the others) and went very well with food. On its own it was fine but not remarkable. Certainly good as a curiosity given the unusual blend.
There are other recommendations in this unappetizingly-named thread.
