Take the 2-minute tour ×  I want to try my hand at making
sourdough starter but live in high altitude and cold weather.
I'm not sure if the altitude is an issue but I don't think my
house is warm enough on its own to allow a starter to properly
rise and ferment. Aside from I'm wondering if there are any
other ways to create a warm, moist environment in which a
starter could be successful.  share|improve this question If
your house is warm enough for a person to live in, it will be
warm enough for yeasts and bacteria. Maybe not in their optimal
temperature, but they will survive and reproduce. –  J.A.I.L.

water heater? The room or the closet that houses it should be
warm enough. That's where I grow my starter. (That's also where
I bulk ferment and proof my loaves).  The altitude is not an
issue. There are yeasts and bacteria on top of Mt. Everest.

add 190 g water @ 78 F (26 C), 94 g brea
