Rather than just (re-)introducing this beer I’m going to offer a relevant and quick lesson on reading the LCBO website. The product page for the Nostradamus Belgian strong says that it’s discontinued, but the inventory page shows 1,800 bottles (a very rough estimate) spread across 65 stores. That’s a hell of a lot of beer for a special season release. For regular listings the discontinued notice means that the LCBO no longer adds to their inventory of that product, in that packaging format. For the seasonal release beers or brewery feature beers it seems to just mean that a product is from the previous cycle. In this case, Nostradamus was part of the winter release and the spring release has started to roll out.
Beer is a fragile product, so the discontinued notice might often be a good indicator to steer clear. With its higher alcohol and low hop bitterness I’m less concerned about the Nostradamus and may pick up a few bottles myself for some cellar aging.
