Heirloom tomatoes

Most of the tomatoes we grow are of the Big Boy, Better Boy hybrid variety, fast growing fast producing. These hybrids usually produce fruit at 72 days from planting in the ground. We started growing a few heirloom tomatoes several years ago and now we have a whole raised bed dedicated to them.  We grow the Brandywine variety of heirloom tomato. The difference between the hybrids and the heirloom? The maturation date is longer, around 82 days instead of 72. The color is more of a reddish purple instead of bright red. Lastly, the Brandywine are the largest and best tasting of all the ones we grow.
Check out the picture. This could be 5 sandwiches from one tomato but will probably be 2 very, very juicy ones instead.
