Yet more wash issues

Post by Jennysgin » Sat Jul 06, 2019 1:25 pm

Ok, so I'm still struggling to get a decent ferment :roll:

The first (turbo that came with the still) got infected due to my impatience.
I tried a kale after that. It went pink and smelled a bit funky.
Reckon I hadn't erased all traces of infection from the first one so have now started a 3rd attempt.
Kale again, after bleaching the life out of everything!

It's been going a week and seemed to have slowed down to not much activity so I've just checked it. It's still at 1050 (SG maybe a bit high - 1082). It's not pink this time which is an improvement but hasn't gone down as much as I'd have hoped.
It's at a fairly steady 29-30oC with a brew mat and a camp mat wrapped around it so that should be ok for the allinsons yeast.

Am I just expecting it to move more quickly than it is? We have fairly soft water here so I also wondered if that's affecting it.

Any thoughts?

Current plan is wrap it back up again and leave it another week or 3! At least I've got some funky pink stuff to try and salvage! :lol:

*Edit: Mr eBay just delivered a pH meter! :D 2.3ish this may be part of the problem

Three things that will slow a wash down. Temperature, PH and lack of nutrient.

You have the temp covered and now the PH. Stick some bicarb in there and take it back up to 5.0. Also add another teaspoon of nutrient per 25 litres. It should take off again and you will see improvement within a few hours.

I started a corn wash and added the yeast starter at 10pm on Thursday night. Its down to sg 1030 as of this morning. If you use the 7 day ferment recipe as a guide that I have previously posted, you shouldn't have any problems. The extra nutrient addition on day four gives it a boost to help the vitamin and epsom salts already added.

Thanks SB

When I realised how low it was I added a huge whack of bicarb and got it up to 4.9

I don't have any vitamins or nutrient at the mo as I'd used kale for nutrient. Maybe see what's around the house and look into getting some, probably online.

Any CO2 cap I had is now well gone so let's hope I've not infected yet another one! :lol:

Guess I'm in this learning process for the long haul! :roll:
Maybe try your one next time. Epson salts, Citric acid, bicarb, nutrient and multi-vits? Is the citric and bicarb acting as a buffer?
I've also got a box of cornflakes waiting to go! :lol:

Anyway, hope your corn mash continues well. I'll keep an eye on pH.

It has to be Ph Jenny.
Here in London hard water never have a sticky one (careful Mash),
Have done 100's of Kale washes as per recipe. The Kale juice is
all the nutrient I need , Allinsons at 30c 5kg 25ltrs down below 1000
and cleared in 18 days.
So it must be your water Jenny.
Ours normally reads 7 or near, given up testing it now.

Hi Jen

I had similar problems my water is very soft and comes from the lake District.

A pH 2.3 is causing your wash to stall as stillbrewing says.

What works for me now is I add some lime powder bought from animal feed stores it acts quickly similar to bicarb. I use a similar recipe to the 7 day ferment recipe

Per 25 litres
I add one level tbsp of gypsum
One level tbsp of citric acid.
One level tbsp of lime powder (similar to bicarb)

You still need to add nutrients of your choice the above is only to buffer ph
Check your pH before you start

I adjust the pH to 5 before pitching the yeast (use citric acid to lower bicarb to raise) it gets the pH to a better starting point for the yeast they don't try and reduce as much.

Check the pH after 12/24 hours you want it to be around 4.4 add your bicarb accordingly to get to this range it should stay at that for the rest of the ferment.

Since I adopted this approach I have no problems usually finished in 4/5 days and I do 100 litre batches

Hope this helps if you are struggling with infections can I suggest using more yeast I use 2 full tins of Allison's per 100l batch.

Deja pooh. I've seen this shit before :chart_with_downwards_trend:

It's probably not relevant, but starsan or vwp steriliser or similar would be a worthwhile small investment instead of using bleach.
Slowly slowly, catchy funky

Don't stress the yeast

When I used to make wine everything was sterilized as a matter of course. It used to take me ages to get prepped but nowadays I don't sterilize at all. I might have been lucky with about the 50 or so washes I have created but never had a problem with infection whilst using bread yeast. A good wash with hot, soapy water and a good rinse is the way I do it nowadays.

Have sterilizers like Starsan been discontinued. Was reading something about the lack of availability of it on a homebrew Facebook group yesterday.

Lots of good thoughts, thanks folks.
I used bleach because the wee tub of no-rinse stuff was running out but reckon I maybe needed something stronger anyway.
VWP is on the shopping list! ;)
