At Wednesday night's barbecue at the the Oakville experimental station, local sausages off the grill were the order of the day. A selection of mustards were offered too. I had the chance to try Sierra Nevada Stout Stoneground Mustard for the first time - didn't even know they made mustard! Spicy hot with a freshness of flavor that really made everything come alive. And, yes, it did have some taste of stout. One of the other guests said that that as good as this one is, he liked the Porter mustard even more.
