So many points to touch upon. First, I'm a lover of heirlooms. I had 256 tomato plants in my garden this year and only 3 were hybrids. Second, I love brandywines, many varieties, some better than others, few that are great producers, although there are a couple that produce fantasticly. Third, Mortgage lifters have never done well in my gardens, for the last three years.
When you say put up for the winter, are you canning, freezing, dehydrating?
If canning or dehydrating I would recommend Tomatoes like Opalka, San Marzano, Super Marzano or other paste types. I never had a lot of luck with Roma's, as they seem prevalant to blossom end rot, and their taste can vary tremendously.
Our best tasting sauces that we canned were those made from Cherokee purple's. Also a mixture of "Cowlick" Brandywine, Caspian Pink, and Cherokee Purple. I found Black Brandywine and Red Brandywine mix to be pretty good also. Usually, those that taste best in the garden, taste best as sauce. I just posted a tomato year in review on another forum a day or two ago that you might find interesting, as I did all the varieties that I planted this year.
Check under Heirloom Gardening at IDIG. It will list taste, production, and comments.
I don't think hybrids produce better than heirlooms, and I certainly don't think they taste better. Perhaps, the better term to use is open pollinaters or OP's instead of heirlooms. OP's also seem to be more disease resistant for me, especially the potato-leaf varieties. Good luck with your choices!

We've always canned Mortgage Lifters with no problems. But for paste, etc. have you considered some of the oxheart tomatoes? We grow a yellow oxheart every year that is very meaty, and I know there are several red varieties available. Just a thought...

I grew New Yorker, Cambells 1327, and Heinz 1429 this year. They are all determinate plants that produce a high yield(per leaf area) of nice medium-sized red tomatoes. The ripening was concentrated mostly over a 2-3 week period.
Sioux produced quite well for me on indeterminate plants.

Hi Camo,

Would you please provide a link to your tomato review?

Drloyd,
I'm not sure if this will work, my computer experience doesn't equal my tomato growing experience.

be sure to check the 4 pages of additional comments in the addendums on pgs. 4-5
I also had much more detailed accounts of taste tests throughout the growing season. Hope you find it useful. I have no typing skills so I peck with one finger and it takes time! Happy Gardening!

I grew Brandy Boy and Cherokee Purple this year and BOTH were delicious... Brandy Boy had a better yield for me, and didn't crack quite so much, but both were good choices overall. I haven't tried many heirlooms yet though, so I don't really know how Brandy Boy compares to them.

To me Mortgage Lifter is an average-good beefsteak heirloom that can easily be substituted out for other reds or pinks that would be as good or better. For me Prudens Purple produces earlier, puts out as much fruit and tastes comparable. Giant Syrian produced more and tasted better to me, and some others (Coustralee, Neve's Azorean Red, Brandywine red potatoleaf were comparable to ML). What about golds, bicolors, or greens just for fun, rather than ML?

ccaggiano,
You don't say where your located, but going by the tomatoes that you listed as doing well I would guess zone 6a or 6b or very close to them.
I wanted to add that as far as a cherry tomato goes, I find Sun-gold, which is a hybrid, to be the best tasting and most productive. It is the only hybrid that can be found in my gardens year after year. Everything else is usually heirlooms and most of them potato-leafed varieties. Good Luck with your choices!
