WSET DIPLOMA D1 ACTUAL EXAM SOLVED
QUESTIONS COMPLETE PREPARATION
RESOURCE
●● Rootstocks resistant to root-knot nematodes
Answer: Ramsey and Dog Ridge (both vitis champini)
●● Rootstocks resistant to draught
Answer: 110 R(ichter), 140 R(uggeri)
hybrids of v. rupestris and v. berlandieri
they root deeply and quickly
●● Rootstocks tolerant to waterlogged soils (high rainfall/soils retaining
water)
Answer: v. riparia (Riparia Gloire)
●● Rootstocks tolerant to salinity in soils
Answer: 1103 Paulsen
●● Rootstocks tolerant to acidic soils
Answer: 99 Richter
110 Richter
,hybrids of v. rupetris and v. berlandieri
●● Main grape varieties
Answer: vitis vinifera (native to Eurasia)
Vitis Riparia
v. Berlandieri
v. rupestris
above mainly used for rootstocks
●● Anatomy of the vine: main elements
Answer: roots
permanent wood (trunk)
one year old wood
main shoots
●● Structure of the shoots
Answer: Main shoots
the stem
nodes
canes - lignified green shoots
buds
petiole (leaf stalk)
,●● kinds of buds
Answer: Compound buds (latent buds) - break open in the following
season
Prompt buds - form and break in the same growing season, produce
lateral shoots
●● canopy elements
Answer: lateral shoots
tendrils
leaves
inflorences
bunches
grapes (pulp, skin seeds)
●● Vine propagation
Answer: 1. Cutting - allows usage of rootstocks, can be treated for
disease
2. Layering - burying a cane and cutting it off once it establishes root;
cannot be grafted
●● Why use different clones?
Answer: yields
, berry size
resistance to disease
skin thickness
●● Mass selection (Selection Massale)
Answer: growers cultivate their own cuttings
expensive and labor intensive, takes a long time
●● What is a cross?
Answer: when parents of the variety are of the same species (Pinot
Noir+Cinsault=Pinotage)
●● What is a hybrid?
Answer: When parents are of different species (Ugni
Blanc+Seibel=Vidal Blanc)
●● Vine growth cycle
Answer: Dormancy (jan-march/may-sept)
Budburst (march-april/sept-oct)
Shoot and leaf growth (march-julysept-jan)
Flowering and fruit set (may-june/nov-dec)
Véraison and berry ripening (june-october/dec-april)
Harvest (sept-october/march-may)
