After walking into Vinologia's, I mentioned to the bartender that I was there on the recommendation of

Dalva's 1952 Golden White Colheita - this was amazing! and approaching the last year of bottling (300 or so left)
Krohn's 1964 White Colheita
Romariz's 1963 Colheita
Romariz's Over 40 yrs old Tawny
Sao Pedro Das Aguias' Over 40 Years Tawny
Quinta do Porto Estanho's 20 Years Old Tawny (limited edition) - tasted with the regular 20 years old and this one was noticeably different (and tastier!)
Quinta Santa Eufemia's 40 Years Old Tawny
Quinta Santa Eufemia's 30 Years Old Tawny
Just a wonderful tasting overall!
I'll be posting my tasting notes in the week to come.
Goncalo - A big thank you for the tastings and sharing your knowledge. I will be back someday!
