Went here last night for the first time to get an idea of what they've been brewing up!
We sat on the patio upstairs. Very nice, if a little sterile in terms of decor and ambiance.
Our server was excellent. Very friendly, prompt and was able to answer all our questions about the various beers they were offering on tap that night. Even made his own suggestions, and was honest about his preferences. Very much appreciated. In fact, the server who greeted us when we arrived was also nice. A friendly vibe permeated throughout, that counteracted some of the iciness I've encountered at other popular west-end breweries. *cough* Bellwoods.
On to the beer...
If I recall correctly, we sampled their blueberry IPA, Pina Colada IPA, basic sour, amber saison, apricot saison, and one of the two pale ales. Would have liked to have tried their basic IPA, but they were out of stock.
Overall, the beer experience was okay. Nothing spectacular, but interesting at least. The highlight for everyone at the table was the pina colada IPA. Very nice balance of subtle pineapple and coconut flavours, with a nice mouthfeel and depth to it. Not too much carbonation and a nice creaminess, like it's namesake. The apricot saison was also very nice, capturing that apricot tartness that you don't typically find in other apricot ales on the market. The amber saison was also unique, and very drinkable.
The lowlight for me was the blueberry IPA, which was watery and devoid of hops, tasting more like a weak sour. The blueberry flavour was too subdued. I didn't taste it at all on my first sip. Their basic sour beer we tried was also too light-bodied and one-dimensional, and the pale ale had an odd muddy flavour, likely from the use of a rare type of earthy hop which I wasn't familiar with. Perhaps it just wasn't to my taste.
The beers all have overly long, complicated names that I can't imagine is helping anyone remember them. Bottle shop prices were also pretty steep ($9 for a 500ml of the pina Colada IPA, for instance) so we skipped on that.
We stuck to a liquid diet, but the food being delivered around us smelled very tasty!
In summary, I'd be happy to return to Rorschach, though it wouldn't be my first choice. Interested to see what other fascinating beers they come up with. Hopefully bottle shop prices come down in the future, although it's unlikely given the size of the space (rent must be a lot).
Give Rorschach a shot!
