I just get a leaven (levain) identify as from San francisco and supply by somebody in england.
I am worry because the shipping took 9 days.
1-i feed it with 250 gr of water and same of flour.
2-after 20 hours it was bubbling but no volume increase.
3-now 28 hours, about 10% increase of volume.
my sources are not availables and i can't find any specific answer to my situation.
