The brewer, based in Cladoch on the Isle of Arran, developed cashflow
problems as a result of what administrator Pricewaterhouse Coopers called "operational difficulties in getting product to market in sufficient volumes".
The company employs 11 people and has a turnover of around ú1 million.
Since the brewery was founded in 2000 by Richard and Elisabeth Roberts,
its Arran Blonde had become a stock line in the portfolio of many
specialist independent beer retailers and has won multiple listings.
Graham Martin, joint administrator at Pricewaterhouse Coopers, said: "The beer produced by Arran has been very well-received in its markets.
"We expect interest from parties who will have the ability to take the business to the next stage of its development in continuing to expand its brand presence and its channel to market.
"The business will be of interest to an existing brewer seeking to add brands to its portfolio, or an individual seeking
to take advantage of the lifestyle afforded by operating such a business on
Martin said there had been interest from "more than one party".
The future of Belgium's Liefmans brewery, also in administration, still hangs in the balance, with a decision on its future due to be made by early next week.
Duvel Moortgat is still the favourite to succeed with an acquisition bid and has been granted an interim licence to brew at the Liefmans site.
But Ian Clay, managing director of Liefmans' UK partner James Clay, said Duvel had not yet exercised this right, and that leaves customers to mop up remaining pre-crash stocks - though listings had been lost.
