Here are some health comparisons between Green and Black olives:
From this comparison, it looks like black olives are healthier in general, but neither should be considered unhealthy.
Green olives are a little unripe, but still ready to eat. Black olives are the same olives, but much riper. Green olives turn black as they mature.
You can add black olives to your salad if you'd like, but a common green salad does not usually have them.
Black olives are actually green olives that are ripe. There are many types of olives and many of them are already dark in color. But the basic green olive (neé spanish olive or manzinilla olive) ripen over time into black olives ;)
In most cases, yes for black olives. However, green olives are packed in a brine that is heavy with salt, so, no for green olives.
Olives grow on olive trees in Spain, Italy, Greece, and the US. The black (ripe) olives have a stronger, more pungent taste than green olives. The reason that we don't taste the bitterness of the black olives (when we buy them in a can) is because most of the oil and flavor is taken out, when marinated in water with a slight bit of vinegar and just a very small amount of salt. The green olives that we buy in the jar are marinated in water with a bit of vinegar and lots of brine salt, and often stuffed with pimentos. The brine salt and vinegar kills the bitterness of the olives; this is why in the US when you taste green or black olives , you usually can't taste the original authentic flavor. Another difference is the curing. Olives are cured in brine (salt and water). A green olive is picked early so it remains green after curing. A black olive stays on the tree longer and is black. It is black when cured, too.
Green or black. Some are also grey or purple.
I would say it's probably more of an esthetic thing. Black olives wouldn't look appetizing in a jar with all the black liquid in it.Many green olives are either naturally fermented or acidified and do not require a metal can. Most black olives are a low-acid food and require a higher heat canning process - which is more easily accomplished in a metal can.
Green and brown.
Black Olives are ripened Green Olives, so any Country mainly around the Mediterranean would have Black Olives, Including and not limited to Italy, Greece, Spain, France among others. All Olives start out Green then turn Black....
Many people young and old enjoy eating olives. There are several different kinds of olives, including green, black, oil cured, and stuffed.
Yes, black olives are grown on olive trees. The black and green olive comes off the same tree. It is when they are picked and processed that makes them black or green. One of the biggest olive tree areas in the states is in CA and southern Italy in the world.
Rainbow colored olives are found here. They are several shades of green, some are black, and others are almost purple.
