My husband and I (very active 74 and 64 yo) will spend 5 days in Porto with two 25 yo daughters then 2 weeks in Lisbon without the girls. We all share an interest in wine and food. We love cooking classes and I’d like to scope out some vineyard visits as well (perhaps with a local guide). Port of course but also wine. If you are familiar with the Italian Food Days tours in Italy that type of fun food/wine experience is amazing so if there is a Portuguese analogue I’d love to know. I am looking for Fodorite suggestions on these topics. One other relevant point as to food is that my husband has celiac so gluten free options are a must. We will be in Porto in late May then Lisbon from 5-31 until 6-13, Thanks in advance.
