It always annoys me when you go to buy cucumber seedlings to find that most are labelled as 'Burpless'. I immediately translate that as boring and tasteless cucumbers. A good cucumber deserves a good burp; if it is any good ;)
Years ago when vegetables tasted better there no option of a burpless variety.
And, I don't recall back then that people burped more.
In some cultures, a good after dinner belch is a sign of appreciation for the meal.
A belch just, well, happens. Most can be politely suppressed.
So avoid those tasteless and burpless cucumbers (you know the type that come wrapped in cling wrap plastic; for your convenience) and look for the heirloom varieties and enjoy the taste.
When buying cucumber seedlings, look for the old traditional types with a Diggers label.
