Hey guys, its probably a massive noob question but i'm struggling to get my head around something i thought i have understood for years!
For the most part, final gravity is determined by the mash temperature, where high temps = more unfermentables and higher FG. Low temps = more fermentables and lower FG.
Crystals have some undermentable sugars due to roasting process and add different flavour depending on roasting temp including sweetness. My understanding is you don't want to use much more than 10-15% as you'll end up with too much sweetness?
If you compare a beer A which is for example 100% base malt OG 1.050 FG 1.010 to beer B which is 90% base malt and 10% crystal OG 1.050 - will the FG be the same as beer A if mashed at the same temperature/same yeast attenuation?
If yes, do crystals add perceived sweetness which isn't measured by FG?
If no, crystals increase FG, how does beersmith work out the FG when using crystal?
Thanks
