Quinta de Azevedo Reserva Vinho Verde 2017 - This seems good value usual 10 eur here, i think that one will grant you a superb experience very cool and with some seafood! Just never had that year in particual but i know those grapes you cant get any other place... Also a bit of arinto will grant it some extra magic!
Herdade Do Esporao Bico Amarelo - i would get this one for value sake, this place, Esporão, makes a lot of good wines with a no bs approach and good relation price vs quality. A good staple to have also cool always with some fish maybe, seafood is also a good companion.
Reguengo de Melgaço - This one is golden imo, usually the wines from Monção and melgaço are made with only one or 2 grapes unlike most Portuguese wines that get up to 4 types of grape for one wine, Anything you see with the grapes ALVARINHO and also ARINTO you are on a sure bet. I did not read all the grapes for each one, always keep in mind with this green one, Arinto will make for super fruity ends and Alvarinho is a sweet yet pungent grape that will refresh you on hot days! You cant go wrong if you buy from this DOC's and grapes!
Let me know what you get and post when you dine it!
