I have a question regarding my primary fermentations. Ive been home brewing since 1987 and more specifically all-grain since about 1996. I used to brew using city water and now I brew (since 2002) using well water. My well water goes through a water (salt based) softener which reduces my calcium and magnesium and I guess some iron, in exchange for sodium. I have noticed that since using this newer well water source that my fermentations happen slowly. The wort still ferments out to the correct final gravity, its just that it takes about 7 10 days, whereas before it took about 3 4 days. Ive never have really done any PH testing and I know the real difference is obviously related to the change in water chemistry. I have experimented slightly with using a portion of the water for the mash straight from the well, therefore bypassing the water softener, but I have noticed any significant change. I figure that my water softener works on the principle of ion-exchange, which will take the 'hardening' ions and replace them with sodium, so the resulting water is maybe too high in sodium to brew with.
The beer taste good, its just that sometimes I like to brew in successive weekends in order to use the yeast from my prior batch, and most times now the primary from the previous batch is not done fermenting. Right now I have a batch (1.080 OG) from last Saturday's brew day in my primary with a big foamy (3.5 inches), meringue-like head, but not much activity in my airlock. I'd like to brew this weekend again but I hate to disturb it too.
I had my well water tested a couple of times since 2002, but I would love to know what I may be able to try to see a change in the fermentation time. Maybe next time Ill buy a 5 gallon bottle of water for my next mash and see what happens. If Im high on sodium and low on calcium and magnesium, what would I need to add to my water? Please respond with any thoughts and thanks in advance. Sorry for the book!
