Vernsgal----Nope, don't do a thing to it. Just leave it alone. Have a safe trip. See ya when you return.
Tomm----No, we don't even measure TA on our fruit wines. We strictly work with PH because we came to the realization, thru some experiments, how critical PH is to the flavor. Some people may disagree with this, but it is what we discovered.
Here's what we do. Once the fruit is thawed we take a PH reading and adjust as needed--then we set the brix.
Yes, we DO shoot for a certain PH. After 24 years, and many experiments, we have found the PH level we desire for each wine we make. Typically on red style wines--even when made from fruit--we shoot for a 3.4 PH On some whites, like a pear or apple, we shoot for 3.3 to 3.4 On Niagara, which is a white grape--we shoot for 3.2 Higher than that, it's like dishwater.
Strawberry, we like to get above 3.4 or else it's too tart and you have to use more sugar to get it balanced to the acid.
You know, this also depends on HOW you make your wines. We are usually using no water---so the acids are very concentrated and PH control is real important. But if you're making a wine with water addition and the resulting delicate flavor, you might shoot for a bit higher PH because the water dilutes and lowers the acids. So you see, one size doesn't fit all. You have to consider HOW you're gonna make this wine. Your whole goal is to have balance between the acids and the sweetness. Tasting the juice as you set the PH does help you to find a range that YOU like. Keep good records on the PH level you like for each of your wines once you decide the style in which you like making them. Makes it much easier when you're standing at the primary, trying to duplicate that great wine you made 2 years ago.
Don't forget that you can also use malic metabolizing cultures like 71B to help manage the harsh bite of malic fruits. Makes the wine --especially blackberry and pear--nice and smooth.
