AG#41 – Saison au Jasmine


This is probably the last saison I’m going to do for the rest of the year. I’ve done a fair few at this stage and while I wanted to get some value out of the two vials of yeast that went into all of these saisons, it’s now time to mix things up a bit.

I’ve always liked the aroma of jasmine – it reminds me of long holidays in Thailand. I figured a floral, fruity, spicy saison would be a great base beer to put jasmine into.

16/08/2015 – Not the best brew day I’ve ever had. It was a bit spur of the moment, and I didn’t really bother with a recipe, just winging it by using the Lemon Saison recipe as a guide. I replaced the Sorachi Ace hops in that recipe, which have a high alpha rating, with Styrian Goldings, which are a very low alpha hop. I’m going to do a hop tea of Sorachi Ace to try to bring the IBUs up from 12! I also had much higher efficiency than expected, 1.066 versus 1.055. This is because I never adjusted my brewhouse efficiency after the last time I did a BIAB brew. Plus I had lots of spills and the brew day was just a drag in general. I’m not sure how much jasmine flavour I got out of 11g of flowers added at flameout, but I might have to do a jasmine tea when I rack this to secondary.

23/08/2015 – Disaster with this, I was racking it to secondary because I need the yeast cake for another diaster of a brew, and there’s a serious bang of fusels off it. Though I’ve just realised writing this that it’s only been in the fermenter a week. However, I did notice that the fermentation was far too fast on it, with the yeast having dropped after 24-36 hours. There might be enough residual job to finish the job in secondary, but I think this might be a lost batch. I’ll leave it a week or two and then have a taste.

30/08/2015 – Dumped. Still tastes shitty. Could be the jasmine giving the off flavours or could be the hop tea I added. Whatever the cause, I’m not wasting bottles or my time on this batch. A thankfully rare occurrence for me to dump a batch.
