Description

Spindasol SB1

Spindasol SB1 is a specific fining agent for wort and it is made of amorphous silicon dioxide at a
concentration of 30%. Technical characteristics such as surface area, particle size and charge are
specifically adjusted in order to achieve the highest possible absorption of coarse break (coarse trub).
After the absorption has occurred through specific weight, an immediate sedimentation takes place.
The technical properties of Spindasol SB1 lead to a difference in performance compared to ordinary
silica sols that have been used up to now. In practice, this leads to a quicker and more efficient
sedimentation. In this way, you limit the pause in the whirlpool and thus reduce the risk of formation of
DMS (Dimethylsulphide). Shorter pauses bring less colour and improve taste stability of the beer.

 

The break from the cast wort, also called coarse trub, consists of large particles (30-80 um in size) which
are slightly heavier than the wort and therefore normally settle down well to form a compact mass. The
initial amount of coarse break is about 6000-8000 mg/L after casting out. After the reduction of coarse
break in the whirlpool it should have decreased to a maximum of 100 mg/L. In some cases, however, not
all breweries achieve this value. The reason can be the design of the lauter tun, whirlpool or centrifuge.
Other obstacles to meet this end are turbid mash separation as a result of malt quality, defective mash
separation, and hop addition containing little or no polyphenols. Insufficient coarse break removal causes
the following problems in beer production:
• coating of the yeast,
• negative influence on final beer stability,
• negative influence on final beer filtration,
• the break also contains the fatty acids of the malt.
In this situation, the addition of Spindasol SB1 definitely helps to improve the quality of the wort.
Compared to other traditional finings, Spindasol SB1 is a pure mineral product and it complies with the
German law for beer purity (Deutsches Reinheitsgebot).

The charging of Spindasol SB1 and its absorption effect do not have a negative influence the taste and
head retention. As far as desirable substances in the fermentation phase are concerned, no absorption
takes place whatsoever. The result of the treatment with Spindasol SB1 is measured by:
• reduction mg/L of coarse break;
• clearer wort;
• more compact sedimentation;
• less waste;
• improved filterability;
• in some cases, improved stability.
Unlike many other silica sols, SiO
2 particles of Spindasol SB1 are not treated with AlO
2. The composition
of Spindasol SB1 allows a relatively low dosage (15-30 g/hL), compared to other silica sols.

DOSAGE
15-30 g/hL.
Higher rates can be necessary in wort composed of large quantities of unmalted components (maize, rice,
syrups). Laboratory testing at different dosages is recommended in order to achieve optimal results.
