Does anyone have any experience with high temp tolerant yeasts and summer brewing.
I've been brewing throughout winter and spring, using electric blanket to maintain 18c to 26c, and have had some awesome results with fruit/sugar washes, I was getting a 75% average for neutral, and 70% for the fruit wash, with one run using a little single marble type reflux condenser without the marble on a 5 liter cooker.
I've done much research, was extra cautious with measurements, sterilizing, dissolving down the dextrose and starting temps.
It bubbled vigorously for 2 or so days, yeast instructions say 2-3 days to finish, possibly up to 5, to make sure, I agitated it once or twice, left it for total 6-7 days.
The SGM read good, it tasted right, no sweetness and a wine like taste (as before), should have been an approx 14% wash, yielding around 3.7 to 4.2 liters at around 75% for a 25 liter wash, but got barely 1 liter and was rank with tails.
I polished it through a filter with 120mg carbon, 1 drip per second around 7 times, but it was still very aromatic and flavored, which it should not have been being a neutral sugar wash.
I checked for vapor leaks and temp control was a bit higher than usual at 86-87c fluctuating, air temp was 38c average.
My only theories are lack of condensation causing vapor loss due to high ambient temp, even though vapor temps were within limits, the cooling water was coming out considerably warmer than usual, and/or excess sugar causing yeast to bog down before finishing, as I understand yeast will tend to dislike high temps once minimum alcohol content is reached (around 14%), and excess sugar will not be processed, which was evident as it was frothing in the pot.
I now have a batch of strawberry mash, due in about 3-4 days, I'll be trying out my new 30 liter cooker with the new tall stainless column pot scrubber type reflux condenser.
Without actual brand naming, it's the Keg type O, which is the Max I'm willing to say

Do you think I should leave the wash for much longer than specified? I know traditionally you can leave a mash mix for a couple of weeks to make sure it's done, but I can't find any confirmation of this with the turbo temp tolerant and 48hr type yeasts, any info on these would be much appreciated, thanks for reading.
