Can you have a blue mash but still hit your target SG?

When I bottled my stout the other day, I used about 1.5g of caster sugar per 330ml bottle, 1/3 tsp. When using carb drops I have found 1 is enough for a 750ml or 500ml bottle but I only use half of one for a 330ml and I get the right carbonation for me.BKBrews said:Thanks mate - I thought so but a bit paranoid being my first attempt. Never even done an extract brew, just threw myself in the deep end with all grain.
In regards to bottle conditioning, I used a calculator to work out the dextrose required to carbonate my IPA and it spat out 2.1g per 330ml bottle. Does this sound right? Any chance of bottle bombs with this level?
What would cause that to happen if my temps were all correct? Could that be caused by temps being a little high? Or low? I was very fastidious in checking the temps regularly - I didn't just get it to heat, add the grain and then leave it for an hour. This was my first time using wheat as well, but I got a really good hot break, so I thought everything was going well.manticle said:Iodine test will show unconverted starch as dark blue or purple.
Potentially you could get expected og without converting everything but unconverted starch should not add gravity points.
I think I've definitely determined that there is a shit load of cold break in the fermenter. That's a given at this point.You have nearly 40% unmalted wheat in the recipe, you haven't done a Glucanase or Protease rest which could contribute to a lot of haze.
As Wes said if your conversion wasn't really finished (blue mash) that to could be adding its own collection of problems.
As could stirring late, I think you have a lot of Hot break in the fermenter, see pick post #71, what you are seeing in the next picture post #72, that mutated jellyfish looking thing is cold break.
On the theme of measuring the temperature, what are you using and how confidant are you that it is telling the truth?
