Kettle sour - pH not changing

[AnimatedGIF]

Hi everyone,
I am brewing Greg Hughes peach and green tea kettle sour, and have added lactic acid and yoghurt and left for 24 hours, but the pH hasn't changed since I measured after adding the acid (4.7).
Is it just a case that yogurt takes longer to sour, or is there anything I can do to get it going? It's at 35°C.
May thanks!

What type of yoghurt did you use, did you check the ingredients? If you used a muller fruit corner you might be waiting a long time

Maybe, but next time just buy the Samsons Probiotics for 4 quid a tub of 30 and be done with it.

5 pills drops the pH down to 3.5 in 24 hours.

Leave it for another day and hopefully it will start to drop.

You mean Swanson?

Thank you both. I put two pots of these in: Waitrose & Partners
I gather live 0% fat is the way to go.
Good shout on the probiotic - I might just do that next time

Ah ok you should in theory be good with that. Might be a question of quantity, not sure.

I use the 'juice' from asda greek style yogurt with dregs of gueze boon and it take a couple of days to drop.

Ingredients
Greek Style Natural Yogurt (Milk), Live Bacterial Cultures (Bifidobacterium, Lactobacillus Bulgaricus, Streptococcus Thermophilus)
