Citra & Raspberry Kettle Sour

[Mrobson]

Citra & Raspberry Kettle Sour using Swanson Probiotics L.Plantarum capsules.

2.1kg Pale Malt
1.4kg Wheat Malt
175g Porridge Oats

Mashed at 66c for an hour.

I brought 22l up to 100c then cooled to 40c and added 17ml of lactic acid along with 7 Swanson capsules. Next I covered the top of the wort with cling film then covered the boil kettle and held it in my brew fridge @ 35c for approximately 50 hours. I don’t have a Ph meter so just tasted it until I was happy with the souring.

Once the soured wort was back up to a boil I added 3.5g of Citra for 30mins then cooled to 68c and did a hop stand with 40g of Citra for 20mins. I cooled to 20c and pitched a packet of S-04 and fermented.

Once the main fermentation appeared to be over, 3kg of rasbperry purée was added (the type that restaurants use on desserts) Once the sugars had been fermented and the gravity was stable I dry hopped with 30g of Citra for three days then bottled. I didn’t bother cold crashing.

I’ve held back a gallon in a Demi John with 3 bottles of Oude Geuze Boon dregs. This will be hidden to mature for as long as I can resist.

Approx Abv (including the sugars from the raspberry purée) - 7%

This is my first sour and overall I’m very happy with the results. The process was very simple and easy!

Is this a method safe from introducing unwanted yeast strains to your system?
I'm just getting into sours having tried a few recently. The colour is amazing!

 

[Mrobson]

Yes. I left the wort in my boil kettle whilst the lactobacillus was doing it’s thing. Once it had, the kettle went strait onto the stove to boil and kill off the lacto.

Everything post boil was treated as normal.

Just to be on the safe side I gave the kettle (and fermenter, once I’d bottled) a quick wash with a bleach solution, a good rinse and then some starsan. Both have been used again.

I like the sound of that. Where do you get the capsules from

Really like the look of this, right up my street. Not sure I'd be happy keeping my burco going for a couple of days to maintain temp. I've seen on the next some transfer to a FV then back to the kettle, would this make a big difference do you think?

I got them from Amazon, think they were about £7 delivered. There’s enough for five/six batches to so overall not very expensive at all, next day delivery too.

I can’t see it making a difference as long as everything is clean. From some research, apparently you can pitch the capsules 40c and leave to cool to room temperature and the wort still sours.

This looks fantastic!! What a colour
