Nicoviotis Orange (mid-sized orange "beefsteak" slicer)
Black Pepper (large, elongated "black" paste *)
Gogosha (large pink slicer, potato-leaf)
Czechoslovakian (large red plum-type paste)
Elfin (OP red grape)
San Marzano Redorta (large, elongated red paste)
Gilbert Italian Plum (very large red paste)
Possibly a couple others, if I can find space elsewhere (friends or family):
Cherry Roma (red cherry)
Snickers ("black" sauce/paste *)
Quebec 1121 (early red paste)
* The "black" tomatoes really ripen on the shelf to somewhere between brick red & chocolate brown. Both are Russian heirlooms. Snickers is a little too juicy for paste, but dissolves quickly into a rich sauce when cooked. One of the most prolific tomatoes I've grown... and what you would expect an heirloom to look like.
Elfin is DW's favorite snacking tomato, and the only tomato I grow every year. More compact plants than most cherry types, and really loaded... I think the plants use hundreds of green tomatoes in lieu of foliage. Tiny seeds, and very meaty - they don't explode when you bite them.
I'm trying to grow fewer varieties than the 12-13 tomatoes I've usually grown, to give them greater separation & concentrate on keeping them pure. There will be more plants of each paste type to make up for that. A couple promiscuous varieties (such as Federle) consistently showed too much crossing, and had to be dropped. I restored one crossed variety (Roughwood Golden Plum) because sources were few; but it took several years, and I don't have time or space to make a habit of doing that.
