One idea could be to arrange a cooking class for your grandpa that teaches him how to make traditional Spanish dishes enjoyed during La Tomatina such as paella and gazpacho. If that's not possible, you could also consider getting him a cookbook with Spanish recipes so he can try making them at home. Another potential gift idea would be to create a scrapbook filled with photos and memorabilia from your grandpa's past trips to Spain, including La Tomatina. Additionally, you could purchase him a set of traditional Spanish wine or an assortment of Spanish cheeses to accompany his cooking.
Or you can get him a star map with the date when he was born.
