Christopher Merrett

Christopher Merret FRS
FRCP
(16 February 1614/1615 – 19 August 1695), also spelt Merrett, was an English physician and scientist. He was the first to document the deliberate addition of sugar for the production of sparkling wine, and produced the first lists of British birds and butterflies.

Life

Merret was born in Winchcombe, Gloucestershire on 16 February; Hunter gives the year of his birth as 1615, which may be 1614 Old Style. In 1632 he went up to Gloucester Hall, Oxford (which later became Worcester College); he received his BA from Oriel in 1635, and his BMed and DMed from Gloucester Hall in 1636 and 1643 respectively.

Merret then practised medicine in London, becoming
Fellow
of the Royal College of Physicians in 1651. Three years later he moved to the RCP's premises at Amen Corner near St Paul's Cathedral, as the first Harveian Librarian, for which he received room and board and a small stipend. But disaster struck in 1666 with the Great Fire of London, which destroyed many of the rooms and most of the books. The college felt that he was no longer needed, but he felt that he had been appointed for life and fought them before the King's Bench twice, losing both times. He was expelled from his rooms and lost his Fellowship.
He was a founding Fellow of the Royal Society, joining May 20, 1663. He became the chairman of the Royal Society's committee concerned with the history of trade and commerce,Koinm, AJ (2000

He died at his home near the chapel in Hatton Garden, on 19 August 1695, and was buried at St Andrew's, Holborn.

Naturalist

Merret collected new plants, maintained a herb garden and compiled one of the first lists of the flora, fauna and minerals of England, the ''Pinax Rerum Naturalium Britannicarum''. The ''Pinax'' was published in 1666 and is an alphabetical catalogue with no explanatory commentary. However it represents the first lists of British birds and butterflies, and contains one of the first statements by an Englishman on the organic origin of fossils:

Metallurgy and glass making

Merret had a particular interest in industrial uses of minerals, publishing papers on smelting and tin mining. In 1662 he translated Antonio Neri’s ''The Art of Glass'' (1611) and added 147 pages of his own, from other authors and his own observations. His descriptions of glassmaking indicate an intimate familiarity with the process, but his modern claim to fame lies in a passing mention to a different field altogether. On 17 December 1662 he presented ''Some Observations concerning the Ordering of Wines'' to the Royal Society. In this paper, unearthed by wine writer Tom Stevenson, Merret describes winemakers adding quantities of sugar and molasses to make the wines drink brisk and sparkling.Mountain, Donna (2005
Sounds of Summer: English wine, a quiet revolution
Transcript of ABC radio programme. Today this would be called the méthode champenoise, the addition of liqueur de tirage in order to stimulate a secondary fermentation that produces the bubbles in sparkling wine.

Spontaneous secondary fermentation had occurred in still wines since antiquity; most glass bottles of the time were not strong enough to contain the high pressures thus generated and so exploding bottles were an occupational hazard of winemaking. Sir Robert Mansell obtained a monopoly on glass production in England in the early 17th century and industrialised the process; his coal-powered factories in Newcastle upon Tyne produced much stronger bottles than were available in France. As a result, the English could deliberately induce a secondary fermentation in wine without the risk of blowing up the bottle, long before Dom Pérignon is traditionally considered to have invented sparkling wine in Champagne around 1697.

Although Merret appears to have been more interested in making glass than in making wine, producers of English sparkling wine such as Ridgeview have been quick to use his name as a generic term to describe their wines.
