Reviews of the variety Doyle's Thornless
Doyle berries are very good. For a long time we thought they were slightly smaller than the TC that I also grow (and of course later-setting berries are smaller), but last season they seemed just as large when picked in the same part of the season.
I am not one for hair-splitting on the subject of "flavor", which is mostly in the mouth of the consumer. If it looks like a blackberry and tastes like a blackberry, I call it a blackberry. If you close your eyes, you won't be able to tell the difference between a fully ripe Doyle and and an equally ripe Triple Crown. Having said that, I don't think a climate like San Diego is ideal for growing any blackberry.
I can't comment on taste of fresh berries, both are kind of sour to my taste. I use both varieties to prepare home preserves. Doyle's (and TC) both make wonderful Jams w/o pectin, just berries and sugar. Tastes absolutely delicious on ice cream or home cheese (like Fromagina Quark, tvorog, etc).
