I meant to get this posted last week sometime, but I forgot and now the tasting is over. It ended on the 24th. It does seem like they have beer and wine festivals often though so hopefully the information will be similar. This particular one was part of the World Autumn Festival at Huis ten Bosch. They offered a variety of tickets. The one we bought was only good for this St. James tasting. It cost 1000-yen for wine or 500-yen for juice. The photo above is the wine, and below is the juice.
The juice was all fizzy and very sugary. The wine was the standard fare.
We could have bought a more expensive ticket that would have allowed tastings at multiple locations as well as a food voucher.
