Crabapples, in the astringent group, provide tannin - a 

 constituent difficult to obtain in making a high-grade cider. 

 The juices of this astringent group also are highly acidic. 

 Only a small quantity of these apples should be used in the 

 blend. 



Use of the following list as a guide in selecting the right 

 blend of varieties. 



Sweet subacid group: Baldwin, Delicious, Cortland, Spartan,

POMOLOGICAL PARAGRAPH 



What are genetic dwarfs ? This question is common now that genetic 

 dwarf varieties of peach, apricot, nectarine and apple are avail- 

 able to commercial orchardists. Genetic dwarfs are selections of 

 natural mutants or mutants induced by radiation that produce trees 

 smaller than typical. Thus, the dwarfing is induced by the scion 

 variety rather than the rootstock. Trees of Starkspur Compact Mac 

 and peach and nectarine varieties are very small and could be grown 

 in a tub on a patio. The internodes on these trees are so short 

 that the wood is flat and thickened. In contrast, trees of the 

 genetic dwarf Compact Red Delicious (Cascade strain) has "normal" 

 appearing wood because of greater internodal spacing and may be 

 10-12 feet in height when on a seedling rootstock. We are currently 

 testing the Compact Red Delicious , Starkspur Compact Mac and some 

 dwarf nectarine varieties at our Horticultural Research Center in 

 Belchertown.
