I grabbed some of the St Stefanus, nice for the price (ordered 6 they sent 12) but would struggle to justify the full retail $20 per bottle in my opinion.
But don't take my word for it, here is a "craft beer enthusiast" review from the DM website:
"Served at 5°C in two ice cold beer glasses, the colour was murky but vibrant with a strong aroma and a slow pour. Unfortunately it wasn't as fruity and full flavoured as we anticipated, and overall we were slightly disappointed.
Nonetheless, we are both convinced that the over ageing of the product had much to do with this. If it were poured at 6 months rather than 18 months we could expect these flavours to be much more full bodied and the bitter finish would be much more subtle".
