LBV's are ideal restaurant wines and can be found under the name of the shipper or individual Quinta. LBV offers the consumer a comparable taste experience, is less expensive and easier to handle. Since there is less sediment, it can be put on a Cruvinet. LBV is made in top vintages and in vintages not widely declared. Select on quality of the wine, not on some mindless vintage rating.
Some older vintages are still available at reasonable prices.
Lesser known vintages can be superb. Keep a few bottles standing upright so they can be poured carefully without disturbing the sediment. If you intend to sell full bottles of old vintages by all means invest in decanters and proper staff training. Older vintages take a great deal of care to serve by the glass. If you use a Cruvinet the wines have to be decanted and put back into the bottle.
