A question about Supplier Instructions

[The Cat]

So - I did a pre packed ingredient all grain kit from here recently.

As I always do I put everything through Brewfather to get the mash and sparge water amounts as The Malt Miller instructions don't suggest them which is fair enough as they don't know what we all use.

Brewfather came to this conclusion compared to the instructions from the supplier.




Even taking it roughly that's a drop of a whole 1% from the instructions - that can't be right can it? I totally accept I am pretty new to this hobby but I've made some nice stuff and most of the abv has come out at between 4 and 5 % of the ones I've done so far and this 7% sounds ambitious to me from the supplier instructions with that weight of grain bill as a noob?

Anyone got any viewpoints on it? I might be missing something stupid admittedly.

Thanks as always for any input.

You haven't input your yeast yet. If it's a highly-attenuating Belgian strain, you should be close. Also you need to check if your efficiency matches their assumed efficiency.

That's the Leffe clone isn't it?
If so mine came out at 1.068 and finished at 1.008, so well over 7% even before the priming sugar.
I always hit, or exceed, the numbers with MM kits.

You've put candi syrup in your recipe, rather than candi rocks. The rocks will be more concentrated than the syrup so that will affect your OG.

Same weight of rocks v sugar. They had an OG of 1.087 in the rocks batch, and 1.078 in the syrup batch.

Thanks all I will have another look.
