The Society launched in Australia in Nov/Dec 2002 and I was one of the first to sign up. Being on the other side of the world, we obviously don't get to visit the members rooms in Edinburgh, etc, but our local directors have developed a programme that seems to suit our calendar and climate.
I enjoy the regular meetings - we have about 4 or 5 tasting nights a year where (in Sydney, at least) between 30 and 50 folks gather to sample 5 of the Society's latest bottlings. Most evenings will also feature a presentation or display, and it's always a good-humoured and relaxed night.
In my opinion, the general overall quality of the bottlings have been excellent. Some are just good, others are absolutely sensational. I've probably sampled over 25 different bottlings by now, and I don't recall being disappointed by any. Others were so good, I couldn't buy a bottle fast enough.
It's important to remember how and why the SMWS came into being - it was chiefly to bottle single casks and to appreciate just how individual and different a single cask from a certain distillery can differ so much from its commercial bottling.
My one and only gripe is the cost of the bottlings. Even though they are all at cask strength, even the youngest bottlings (e.g. a 9yo) sell for at least $155 (Australian dollars). By comparison, an OB 17yo Bowmore costs $120, Lagavulin OB 16yo costs $85, and an OB Macallan 18yo costs $135, so the SMWS bottlings are not cheap.
However, they are unique; good quality; non-chillfiltered, non-coloured, and offer the discerning malt drinker the chance to drink from distilleries that are otherwise not bottled as a single, or have closed, or to simply try an alternative expression of your favourite malt.
