When I first got into wine, the only wine types then considered serious in the UK were claret, Burgundy, hock, Moselle (sic), port, sherry and Madeira. Since then sherry has fallen off that pedestal, though IMO quality and variety has never been better than now. Much to blame was the social habit among elderly aunts and college tutors of offering a choice of "dry" or "medium" sherry out of dusty decanters in which the wines had rested at room temperature for several months with inevitable fading. My eyes were opened to the real quality of dry sherry in the late 60s and early 70s, when drinking it chilled on hot days in restaurants in Madrid and Barcelona. I particularly recall Fino San Patricio but I haven't seen that for many years.
Tio Pepe and La Ina are excellent finos and superb QPR but are difficult to find here in Normandy. The last I bought was during a visit to Rouen. There are producers like Lustau and Barbadillo producing a range of fine sherry all the way from Fino, though Amontillado, Palo Cortado, Oloroso seco & dulce to sweet, dark and thick textured Pedro Ximenez. Though more expensive than Tio Pepe and La Ina, they still represent great QPR compared with comparable quality in more fashionable regions. Just writing this makes me tempts me to revive my plans for making an order of Spanish wine from web sellers like Decantolo or Vinissimus.
