5kg sugar is good. I find any more and you need a turbo or
vodka star yeast and I think bread yeast is better and cheaper.
(snippage)
Not sure about bread yeast being "better". Cheaper, likely.
Generally, turbo's like vodka star etc, are tolerant to 14% ABV. People often wonder/worry about using bread yeast as it's not like it's been tested and details published.
From the mead world, the times when you see mentions of bread yeast is with the JAOM recipe. Now it's not strictly a good method/technique, but it seems like it was developed for nOOb's, so that they can pretty much get all the ingredients from a grocery place/supermarket.
If you looked it up, you'd see Joes admonishing comments in the recipe about no need to take gravity readings etc, but also about using bread yeast (specifically Fleischmans - but that's not available here, it's a US brand). There's plenty of people who have done just that.
While it's a make and forget method, many have actually taken gravity readings - using all the basic number it's IRO 1.125 before yeast pitch and finishes at about 1.035-1.025 so that's sort of 12 to 13.5% ABV - from bread yeast (I've done this recipe with Allinsons, Hovis and Co-Op own brand).
Hence I'm thinking that there should be no reason why it shouldn't work fine with 5kg of sugar per batch of wash.
I'm also very lazy when it comes to being original about this sort of stuff, so I just get my vodka star in bulk quantities (free shipping or money off list sort of thing). Plus it's been a long time since I meddled with TPW, Kale, etc which is why I'm typing this (and not trolling Gaza's comment). It's "thinking aloud" so I can remember..........
Oh and for those who didn't know, when bread production changed from being all "sour dough" to yeast based in the mid-19th century, the yeast used was from a brewery source (I'm sure it's been more tweaked/refined for better CO2 production for rising/proving the bread before it's baked). Just that the very fact that it was brewers yeast that was used suggests a little of why it can be used successfully to make wort/wash without hideous flavour issues..........
