'Red Topaz' boasts the same qualities as its parent 'Topaz' - resistance to diseases, easy growing, delicious taste. Its attractive bright red fruit colour that develops about 10 days earlier gives 'Red Topaz' an advantage in warm, dry areas where the over colour in 'Topaz' can be weaker. These two varieties have become perhaps the most cultivated scab-resistant apple varieties in organic conditions in Europe over the last two decades.
