10 litre kit

[DCLavs]

Does anyone know where I could get an all grain kit to make 10 litres? Looking to make this on the stove using a pot. I know 5 litre kits are available and I could half a 20/23 but looking for 10. Two 5 litre kits are too expensive.

Why not get a 20l kit and split it?

Was looking to try a few different kits at 10l. 5l is too small and 20l too large for me might just have to go with the split. How long would grain keep after opening? I'd be buying crushed. And would opened yeast keep?
