Having been flat out for over month between work and home projects and narrowly failing to cut my fingers off last weekend trying to finish my pergola lean-to I found myself at a bit of loose end this weekend and sufficiently healed to be able to set the grainfather up and do some one handed brewing.
This one isn't going to be to everyone's taste as its a bit of an odd one. I got the idea from
Ocean Water Blue Sour IPA, I like a sour, I like IPA and I will get a perverse delight from dropping a couple of bottles of this round to my dad and his mate who are a little conservative when it comes to beer but still find it in their hearts to drink everything I give them.
The original recipe uses Blue Spirulina and some food dye to give the beer a blue-green colour, it doesn't contribute anything else to the beer so if blue beer is too much it could be left out to create a "normal" sour IPA.
I made some changes to the original recipe, I felt it was too damn strong and having just finished a keg of Belgian Strong I felt that making it less agressive in the alcohol department would make it more enjoyable for my target audience its still going to sit between 6-7% but the original was up around 8%+ and I wanted something that people would be able to drink more than 1 of.
A note on water
The Water where I live has quite a high Sulphate to Chloride ratio, around 3:1 and the more I brew with it the more I notice it is great for IPA and Bitter but rubbish for anything else,
For this beer I wanted a more balanced water for a silkier mouth feel and no sharp edges. So starting with 25L of Ashbeck and 2 Litres of Tap Water, I added some AMS and a couple of grams of Calcium Chloride to the mash and ended up with around 1:1 but I think I needed a lot more Calcium Chloride to make a difference potentially 10-15 grams to get the 0.5-6 I was originally aiming for. That said I was quite happy with the mouthfeel of the post boil sample so fingers crossed I've done enough.
Brew Day
I heated 15L of Ashbeck and mashed in at 65°c, in hindsight I could have gone 66-67 for a bit more body and depending on my results with this brew I will try mashing at a higher temp next time I brew a beer like this. As usual I stirred in until there were no dough balls and stirred it again halfway through the mash and then after mashing out I sparged with 10 Litres of Ashbeck and 2 Litres of Tap water treated with the rest of the AMS and a Campden tablet. Once all the Sparge water had been added I left it to drain through for another 20 or so and started the Boil.
Its the first time I ventured away from the 60 minute boil but I will try and be more dynamic with my boil times going forward, I added 5g of Magnum at 30 mins. At 10 minutes I scooped out 2 litres of wort and and added this to a saucepan on the stove and brought this back to the boil before adding the Lactose and Corn Sugar to the pan. At 5 minutes I returned the contents of the pan to the Kettle and gave it all a good stir.
I put the hop spider in 5 mins from the end and started running the hot wort through the chiller into the kettle to sanitise it. I've found with the counterflow chiller its best to point it in the spent grain until you see wort coming through I've noticed it spits and splutters a bit when it starts so I like to wait until I have steady flow of wort before I point it back into the kettle just in case there is old water or sanitiser in it.
Once the boil was complete I chilled it down to about 78°c and put the Hopstand addition into the hop spider and recirculated the wort through the chiller into the hop spider, I don't know if it makes a difference but in my head it does so thats how I do it. After 20 mins I removed the hop spider having done a few dunk and shakes before I the contents in the spent grain trug. I gave it a good stir and left it for 15 mins or so to settle before chilling and transferring to the FV at around 21-22°c. It looked like Pineapple juice at this point.
The gravity at this point was 1.058 and having had a quick taste it was the smoothest wort I've tasted so I am hopeful that I'll get a good smooth sour beer at the end of it all.
The Yeast was pitched dry and I put the FV in a Fermentation chamber set at 22°c.
Fermentation Activity
Once a Krausen has formed I am going to hit it with the first of two dry hops which will stay in contact with the beer for 3-4 days. The beer will stay in primary until the krausen drops at which point I will add the fruit to a fresh fermenter and transfer the beer on top it it. I'll leave it in secondary for a week or so before purging it and adding the 2nd dry hop for another 2 days or so.
At this point I will adjust the colour using the Spirulina and some blue food colouring if necessary. The original brewer adjusted the flavour using some fruit extracts at this point as well but I am not 100% sure that will be necessary for me as I am using slightly safer (in my opinion) fruit flavours then he did.
