    25 year old bio-dynamic vines planted in a limestone and sandstone-clay soil give this delicious wine, whose ripe citrus fruits (hints of mandarin and ripe grapefruit) are cosseted by good acidity with a saline hint on the long finish. For drinking now to 2021.

Further details
Matthieu Boesch, Domaine Léon Boesch
Rouffach, lieu-dit Ruestgass. Soultzmatt, lieux-dits Clos Zwingel and Breitenberg.
Size of domaine
15 hectares (of which Riesling “Grandes Lignes” is 1.7ha)
100% Riesling (20 yrs old) massale selection on 3309 rootstock. 4500 vines per hectare trained double guyot.
Limestone and sandstone soil 30cm to 1m above the mother rocks. South and East facing hillside. 20% and 40% slopes. 220mtrs and 350mtrs above sea-level.
Certified organic with Ecocert© and bio-dynamic with Demeter©. Debud but never carry out vendanges en vert. Plough 1 row in 2 April to June. Allow grass to grow in the other row until it seeds, then lightly roll it and cut back grass before the harvest in all the rows. Think that it is vital to respect the nitrogen cycle of the vine and so the soils are never ploughed after July 14 in order to allow the vine to ripen the grapes in optimal conditions. Stimulate the vine’s natural defences by silica. Use homeopathic dose of horsetail, nettle and sulphur and very low levels of copper against oidium and mildew. Manual harvest, carefully sorted in the vineyards. 50 hectos per hectare yield.
Pneumatic press. Long slow pressing (8 to 10 hours) of the whole bunch, not followed by a settling period. Vinified in ancient foudres at 12- 24°C. The foudres are not temperature controlled. The wine is allowed to follow its natural course at its own rhythm using its own natural indigenous yeasts. Left on total lees from fermentation, with just one racking in April, but no separation from the lees. Malolactics are permitted (do not add sulphur after alcoholic fermentation) as Matthieu believes this allows a better exchange between the wine and the lees. Aged in the same foudres as for the fermentation for 11 months. No batonnage, no fining, just filtered lightly by cellulose plaque. Bottled in August using their own equipment. 11000 bottles produced on average.
