How about a winemaking kit for your grandson? This could be a great gift that he will enjoy and appreciate. There are several varieties of winemaking kits available at different price ranges, so you can pick one that fits your budget.
Another idea could be to put together a basket of wine-making supplies, such as corks, a bottle filler, a hydrometer, and a thermometer. You could also include a personalized notebook to help him keep track of his winemaking process and tastings.
Lastly, consider getting him a book on winemaking. There are many books available, and they can be a great source of information and inspiration for your grandson. These books cover everything from the history of wine-making to the science behind the process.
Or you can get him a star map with an important date you share.
