Reddit reviews Epic Tomatoes: How to Select and Grow the Best Varieties of All Time

If you have the time, have a read through the book "Epic Tomatoes". It covers everything you need to know about growing heirloom tomatoes.

Epic Tomatoes is a pretty good book about that.

Edit to add:

This Is The Perfect Tomato, But Supermarkets Refuse To Sell It.

That article is about the Garden Gem, but the same people have one called Garden Treasure which is a Brandywine hybrid. This is my first year growing it - tried last year, but growing tomatoes from seeds is a little harder than I thought. I think they really like consistency in temperature and I wasn't giving them that last year. The Gem is kind of a small plant, but the Treasure is a monster. Hopefully we have enough sunshine for it to ripen, summer got off to a slow start here.
