I am not so fond of their "Kasteelbier" line. But I do consider Bacchus as a good choice if you want to get familiar with the Flemish Old Brown beer style.

If you want to turn that 2,75/5 into a 5/5, I would suggest you try a bottle of Rodenbach Alexander.

And you might want to buy some extra bottles to keep for a very long time, since it is not certain that they will continue the production at this point. This beer made a comeback last year after a hiatus of 16 years.

Earlier I also referred to the regular Rodenbach classic as one of the better beers you can buy in a can: https://steemit.com/beer/@davenumero6/5-excellent-canned-beers-for-a-camping-weekend
